SplitMenuButton and Linux Ubuntu
I am using a split menu button (on Linux Ubuntu). I click on the drop-down arrow, and when I move the mouse over a selection, it will sporadically on and off select the button item. The cursor also changes to a text edit cursor, since it drops over a text field. Is this a bug? Is this just on Ubuntu? If this is a known problem - is there a work-around? It seems as if it needs to be over the text characters themselves for the button to work... which makes it very difficult to select.
Thanks,
joe

Hi,
are there any drivers or something else to use alle the Hotkeys in Linux?Welcome to the forums
None of the distos have out of the box support for hotkeys.Try this link

My OS X 10.9 corrupted and i cleaned everything and installed ubuntu linux. I need clean install OSX again and i cant able to reach OS utility now. Please advise
You cannot use a Windows machine.
No idea if this will work because you have/had Ubuntu installed - hit Command + Option + R keys while restarting/booting up. Once in the Utilities, make sure the drive is formatted correctly and erase it, then reinstall the OS. -

Oracle 11gR2 Express Edition on Linux Ubuntu 11.10 howto
h2. Purpose
This document outlines instructions how to install Oracle XE under Ubuntu 11.10.
Ubuntu or Debian based Linux is not on the list of supported operation systems according to the Oracle documentation at http://download.oracle.com/docs/cd/E17781_01/install.112/e18802/toc.htm. You may want to consider virtualization software like Oracle Virtualbox and install Oracle Enterprise Linux as a free and professional alternative to installing XE under Ubuntu. You can also download pre-build virtual machines that include Oracle XE. You can browse http://otn.oracle.com/community/developer-vm for more information.

h4. 11) History
h4. 12) References
h2. 1) Install Linux Ubuntu
The following assumes you have installed Ubuntu 11.10 Desktop Edition for AMD 64-bit, or upgraded from a previous version. Keep in mind that Oracle 11gR2 Express Edition is only available for 64-bit architecture. It is not necessarily a requirement, but I would not bother to install Oracle 11gR2 XE on a system with less than 2 GB of RAM installed. You can download Ubuntu for free at: http://www.ubuntu.com/download/ubuntu and install it using the default settings provided.
You can apply the latest OS patch-sets by clicking the power button icon in the upper right hand corner of the screen and selecting "Updates available..."
h2. 2) Remote Terminal
You will need command line access to perform the installation tasks. Select the top "Dash Home" button of the Unity toolbar and enter the word "terminal", or use CTRL-ALT-t. If you prefer to open a remote terminal session use SSH. Ubuntu does not come with a secure shell login by default. To install it, use the following command:
sudo apt-get install openssh-serverYou cannot login as root unless you set a root password using the "sudo passwd root" command. However, you can get root user access using the "sudo" command, which requires only to re-enter the password of your personal account. Access to "sudo" is controlled by the /etc/sudoers file.
The best way to establish a remote command line session as root is to login with your personal account, e.g.: ssh [email protected], and then type "sudo su -" to become root, or use "sudo <command>" to execute individual commands. If your account does not have "sudo" access you can login as root using "su - root", but will need to know the root password.
h2. 3) Install Additional Software
Oracle 11g Express Edition requires additional software that is not installed by default:
sudo apt-get install alien libaio1 unixodbch2. 4) Managing Swap Space
Oracle demands that the minimum swap space for Oracle Database XE is 2 GB (2095100 KB) or twice the size of RAM, whichever is lesser. Enter the following shell command to verify your swap space:
cat /proc/meminfo | grep -i swap
SwapCached: 0 kB
SwapTotal: 2095100 kB
SwapFree: 2095100 kBYou can increase available swap space by using a swap file as long as disk space permits. The advantage of a swap file versus a swap partition is flexible space management because you can add or delete swap space on demand as necessary. The following will create and enable an additional 1 GB swap file at system startup, located in the /home directory:
Login as root:
sudo su -Enter the following commands:
dd if=/dev/zero of=/home/swapfile bs=1024 count=1048576
mkswap /home/swapfile
swapon /home/swapfile
swapon -aCreate a backup of the original "fstab" file and add the new swap file:
cp /etc/fstab /etc/fstab.backup_`date +%N`
echo '/home/swapfile swap swap defaults 0 0' >> /etc/fstabExit from root and verify the new swap space:
exit
swapon -s
Filename Type Size Used Priority
/dev/sda5 partition 2095100 0 -1
/home/swapfile file 1048572 0 -2Swap space is not a substitute for installed RAM. Swap space is a safeguard that allows the system to move idle processes to disk before the OOM killer will begin to terminate processes in order to free up enough real memory to keep the system operational. The general rule for sizing the swap space depends on the size of installed RAM. If your system has less then 4 GB of RAM the swap space should usually be at least twice this size. If you have more than 8 GB of RAM installed you may consider to use an equal size as swap space. The more RAM you have installed, the less likely you are going to run into memory starvation, and the less likely you are going to need swap space, unless you have a bad process.
h2. 5) Modify Kernel Parameters
Oracle 11gR2 Express Edition requires the following Kernel parameters. Enter the commands exactly as shown:
Login as root:
sudo su -Cut & paste the following directly into a command shell (not a text editor):
cat > /etc/sysctl.d/60-oracle.conf <<-EOF
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65500
kernel.sem=250 32000 100 128
# kernel.shmmax=429496729
kernel.shmmax=107374183
EOFLoad and verify the new kernel parameters:
service procps start
sudo sysctl -q fs.file-max
sudo sysctl -q kernel.shmmax
sudo sysctl -q net.ipv4.ip_local_port_range
sudo sysctl -q kernel.sem The SHMMAX kernel parameter defines the upper memory limit of a process. It is a safeguard to stop a bad process from using all memory and causing RAM starvation. The Linux default is 32 MB. The official Oracle XE installation documentation suggests a value of 4 GB -1 bytes (429496729). Since Oracle 11g XE has a 1 GB memory limit, a smaller footprint will be a better safeguard for the complete system. Setting the SHMMAX parameter to 107374183 will be sufficient.
h2. 6) Oracle Home Directory
At the time of this writing, Enterprise Linux 6 is not supported for Oracle database yet. It is therefore not possible to confirm Oracle ext4 filesystem compatibility, which is default in Ubuntu 11. According to various information, ext4 may cause a performance problem for Oracle 11g database. The following will show you how to add a ext3 partition to your existing setup.
h3. 6.a) Resize the Root Partition
Provided you have sufficient free disk space, you should be able to resize the root partition to create an extra ext3 filesystem. Considering the 11 GB user datafile limit of the Express Edition, 18 GB should be more than enough.
You can use the free Gparted Live CD to shrink your startup volume. Gparted downloads are available at http://sourceforge.net/projects/gparted/files/gparted-live-stable. When burning the CD, pay attention to burn the raw .iso image and not the possibly "mounted" image. If you are using a virtual machine like Oracle Virtualbox, you can mount the .iso image directly. There are going to be a few prompts when the system starts from the CD, but you can press Return to accept the defaults.
When the Gparted window appears:
- Select your ext4 root partition, usually /dev/sda1
- Select the "Resize/Move" button from the toolbar.
- Enter 18000 into the "Free space following" field and press the Return key.
Be careful not not change the start of the partition!
- Click the "Resize/Move" of the dialog and then then the "Apply" toolbar button.
The process may take several minutes - do not abandon it!
- Select the new unallocated free space of ~ 18 GB and push the "New" button.
- Set the file system to "ext3" and label it "oraclexe" and click the "Add" button.
Be sure to label it oraclexe, otherwise the follow-up instructions will fail.
- Finally select "Apply from the toolbar to apply the changes.
- Quit "Gparted", select "Exit" from the desktop and choose "Reboot" to restart the system.
{code}
After the system has restarted, open a terminal command shell.
Login as root:
{code}
sudo su -
{code}
Backup "fstab" and add the UUID of the partition. The "tr" command remove the quotes:
{code}
cp /etc/fstab /etc/fstab_`date +%N`
uuid=`blkid | grep oraclexe | awk '{print $3}'`
uuid=`echo $uuid | tr -d '\042'`
echo $uuid
echo "$uuid /u01 ext3 errors=remount-ro 0 1" >> /etc/fstab
{code}
The UUID is a unique number and should look similar to:
{code}
UUID=d1db753e-b5dd-4a4c-a61e-259c69867b58
{code}
Restart the system:
{code}
reboot
{code}
Verify the success:
{code}
df -h /u01
{code}
h3. 6.b) Setup External Storage
If you prefer to setup an external drive to install Oracle XE, beware that it can be a fatal mistake to make an entry in /etc/fstab to automount your external storage device. An unavailable device in /etc/fstab will prevent a system startup and prompt for appropriate actions at the console.
The following is an example of how to prepare an external storage device to be used for Oracle 11g, including a script to automatically mount an external drive at system startup without the disadvantages of /etc/fstab. The script will also take into consideration that a device name might shift if you attach additional devices.
To find out which USB devices are connected:
{code}
sudo parted -l
{code}
Look for the device that matches your USB storage. For example: /dev/sdb1
{code}
Model: USB 2.0 Flash Disk (scsi)
Disk /dev/sdb: 2064MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 20.5kB 1929MB 1929MB hfs+ mystick
{code}
Initialize the device using ext3 filesystem - this will erase all data. The "-c" option will check for bad blocks (read-only), "-L" is the volume label:
{code}
sudo umount /dev/sdb1
sudo mkfs.ext3 -c -L oraclexe /dev/sdb1
{code}
Install the pmount distribution package:
{code}
sudo apt-get install pmount
{code}
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}
cat > /etc/init.d/oracle-mount <<-EOF
#! /bin/sh
# /etc/init.d/oracle-mount
VOL_UUID=alphanumeric

if [ "\`/usr/bin/pmount | /bin/grep \$VOL_DEVICE\`" ]; then
echo "Error unmounting \$VOL_DEVICE"
else

fi
echo "Usage: /etc/init.d/oracle-u01 {start|stop}"
exit 1

{code}
UUID="3f5e9963-b328-49f3-b3e8-a3561ae34106"
{code}
Logout of root and test the init script:
{code}

{code}
h2. 7) ORA-00845: MEMORY_TARGET
Oracle 11gR2 XE under Ubuntu 11.10 will result in "ORA-00845: MEMORY_TARGET not support on this system" either at Oracle database startup or during the initial installation. Ubuntu 11.10 uses a new version of the "systemd" system and session manager and has migrated away from /dev/shm and other common directories in favor of /run.
There are several ways how to address the problem. You can either enable /dev/shm shared memory, or change the default memory management of Oracle 11g from AMM (Automatic Memory Management) to ASMM (Automatic Shared Memory Management) as it was in used the previous 10g version. Since AMM is one of the new features of 11g, the following will show you how to make to make AMM work.
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}

Install the oracle-shm init script:
{code}
chmod 755 /etc/init.d/oracle-shm
update-rc.d oracle-shm defaults 01 99
{code}
Restart the system:
{code}
reboot
{code}

/run/shm /dev/shm none rw,bind 0 0
{code}
The upper limit of shared memory under Linux is set to 50 % of the installed RAM by default. If your system has less than 2 GB of RAM installed, there is still a chance to run into ORA-00845 error if your shared memory is used by other software.
The verify available shared memory, type the following commands:
{code}
sudo df -h /run/shm
{code}
h2. 8) Installing Oracle 11gR2 Express Edition
The final release version of Oracle 11gR2 Express Edition can be downloaded for free at http://otn.oracle.com/database/express-edition/downloads. The software should automatically downloaded into the "Downloads" folder of your home directory.
Enter the following commands to unpack the installer:
{code}
cd ~/Downloads
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
rm oracle-xe-11.2.0-1.0.x86_64.rpm.zip
{code}
The Debian Linux based package management of Ubuntu is not compatible with the Red Hat package manager. The Oracle installer needs to be converted using the following commands:
{code}
cd ~/Downloads/Disk1
sudo alien --to-deb --scripts oracle-xe-11.2.0-1.0.x86_64.rpm
(This may take a few minutes)
rm oracle-xe-11.2.0-1.0.x86_64.rpm
{code}
The following needs to be set for compatibility:
{code}
sudo ln -s /usr/bin/awk /bin/awk
sudo mkdir /var/lock/subsys
{code}
Ubuntu uses different tools to manage services and system startup scripts. The "chkconfig" tool required by the Oracle installer is not available in Ubuntu. The following will create a file to simulate the "chkconfig" tool.
Login as root:
{code}
sudo su -
{code}
Copy & paste the following *directly* into the command prompt to create a file:
{code}
cat > /sbin/chkconfig <<-EOF
#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Debian based Linux (by dude)
# Only run once.
echo "Simulating /sbin/chkconfig..."
if [[ ! \`tail -n1 /etc/init.d/oracle-xe | grep INIT\` ]]; then
cat >> /etc/init.d/oracle-xe <<-EOM

EOF
{code}
Exit root:
{code}
exit
{code}
Set execute privileges:
{code}
sudo chmod 755 /sbin/chkconfig
{code}
Install Oracle 11gR2 Express Edition entering the following commands:
{code}
cd ~/Downloads/Disk1
sudo dpkg --install ./oracle-xe_11.2.0-2_amd64.deb
(This may take a couple of minutes)
{code}
Run the configuration script to create (clone) the database and follow the screen. Accept the default answers, including "y" to startup the database automatically, or modify as required.
{code}
sudo /etc/init.d/oracle-xe configure
(This can take a few minutes - the installation completed successfully.)
{code}
To verify success, the procedure should end showing:
{code}
Starting Oracle Net Listener...Done
Configuring database...Done
Starting Oracle Database 11g Express Edition instance...Done
Installation completed successfully.
{code}
Set a password for the Oracle account:
{code}
sudo passwd oracle
{code}
h2. 9) Post-Installation
In order to use sqlplus and other tools, the Oracle account requires specific environment variables. The following will set these variables automatically at every Oracle login:
Login as the Oracle user:
{code}
su - oracle
{code}
Copy the default account skeleton files and add the Oracle env script to .profile:
{code}
cp /etc/skel/.bash_logout ./
cp /etc/skel/.bashrc ./
cp /etc/skel/.profile ./
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
By default, the Oracle Database XE graphical user interface is only available at the local server, but not remotely. The following will enable remote logins:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and execute the following:
{code}
sqlplus / as sysdba
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exit
{code}
See http://download.oracle.com/docs/cd/E17781_01/admin.112/e18585/toc.htm for more information.
h3. a) Unity desktop configurations
The Oracle XE menu under the previous Gnome Classic desktop shows several useful scripts to backup the database, start and stop the database, etc. Under the Unity based desktop this menu is not available. You can either switch to the Gnome Classic desktop as outlined in chapter 2, or perform the following steps to modify and copy the scripts as outlined below. The start and stop database scripts will also be modified to perform a progress feedback.
Login as user root:
{code}
sudo su -
{code}
Convert desktop files:
{code}
cd /usr/share/applications
sed -i 's/Categories.*/Categories=Database;Office;Development;/g' oraclexe*
sed -i 's/MultipleArgs/X-MultipleArgs/g' oraclexe*
sed -i 's/MimeType.*/MimeType=application\/x-database/g' oraclexe*
sed -i 's/.png//g' oraclexe*
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-startdb.desktop
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-stopdb.desktop
{code}
Exit root:
{code}
exit
{code}
Login as user Oracle:
{code}
su - oracle
{code}
Modify database start and stop scripts:
{code}
cd /u01/app/oracle/product/11.2.0/xe/config/scripts
cp startdb.sh start.sh_orig
cp stopdb.sh stopdb.sh_orig
sed -i 's/>.*//g' startdb.sh
sed -i 's/>.*//g' stopdb.sh
{code}
You will need SYSDBA privileges and set Oracle environment variables in order to use your regular user account.
Login to your regular user account:
{code}
su - dude
{code}
Enter the folowing command:
{code}
sudo usermod -a -G dba dude
{code}
Then update your profile to automatically set the necessary Oracle environment variables:
{code}
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
Update your Desktop folder to contain useful Oracle XE scripts:
{code}
cp /usr/share/applications/oraclexe* ~/Desktop
chmod 750 ~/Desktop/oraclexe*
{code}
To verify success re-login and try "sqlplus":
{code}
su - oracle
sqlplus / as sysdba
{code}
h2. 10) Tips and Troubleshooting
h3. 10. a) Port 1521 appears to be in use by another application
Error: Port 1521 appears to be in use by another application. Specify a different port.This error happens after a previously unsuccessful configuration attempt using /etc/init.d/oracle-xe configure script. The script was able to start the Listener process, but most likely failed to continue to clone the database, e.g. ORA-00845. The following should correct the problem:
Determine the oracle listener process that is already running:
{code}
$ ps -ef | grep oracle
{code}
Your output should be similar to:
{code}
oracle 19789 1 0 19:46 ? 00:00:00 /u01/app/oracle/product/11.2.0/xe/bin/tnslsnr
{code}
Then kill the process, using the appropriate process id, for instance:
{code}
$ sudo kill -9 19789
{code}
h3. 10.b) cannot touch `/var/lock/subsys/listener': No such file or directory
Starting Oracle Net Listener...touch: cannot touch `/var/lock/subsys/listener': No such file or directoryThis error occurs when you run /etc/init.d/oracle-xe configure, but failed the preinstallation step to create the /var//lock/subsys directory as outlined in chapter 8.
h3. 10.c) ORA-00845: MEMORY_TARGET
ORA-00845: MEMORY_TARGET not supported on this system See chapter 7 to enable /dev/shm and verify free space available in /run/shm
h3. 10.d) Apex ADMIN password
According to the Oracle documentation, the password for the INTERNAL and ADMIN Oracle Application Express user accounts is initially the same as the SYS and SYSTEM administrative user accounts. Well, I tried several times without success. To reset the Apex Admin password:
Login as user oracle:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
{code}
At the SQL prompt, type the following to be prompted to change the password:
{code}
SQL> @?/apex/apxxepwd.sql
exit
{code}
When done, open your browser and go to http://127.0.0.1:8080/apex
Workspace: Internal
Username: ADMIN
Password: password you set with apxxepwd.sql
I will prompt you to reset the password:
old password: password you set with apxxepwd.sql
new password: final_password
You can also login as the Apex Admin using http://127.0.0.1:8080/apex/apex_admin
h3. 10.e) SYS and SYSTEM password
Use the following commands to reset the SYS and SYSTEM passwords if necessary:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following at the SQL prompt:

Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

Nokia E90 and Linux... how compatible are they?
I am hoping to soon upgrade my current mobile phone (Nokia 6822) and separate PDA (a Palm Tungsten T3) to a Nokia E90. However, I have reservations...
Does anyone have any knowledge or experience about how the Nokia E90 syncs with Linux Ubuntu? I know it doesn't come "out the box" with Linux support, unfortunately, but what about after-market solutions and work-arounds?
I don't mind if I sync through a USB cable or Bluetooth, as long as it works. (I really want to avoid running WINE or something similar though...)
Any thoughts and suggestions appreciated...!
(And the day Nokia issues Linux support I, for one, will be a happy bunny!)
Message Edited by prodromoi on 11-Jan-2008 02:30 PMBefore you get your E90 you MUST think about support , I got 2 BRAND NEW and I have been a NOKIA costumer for more than 10 years (yes , I own 2 communicators of each model ever built and A LOT of accessories and other models as well...) The paint job started peeling off in about 2 weeks , wrote NOT COMPLAINING but looking for any advise , they replied that there is no support for E90 in Taiwan... but they still working good and I decided to cover them with plastic skin , later on they released an "upgrade" that does NOTHING and I did not check asuming that NOKIA of course will do things always thinking in functionality... to make it short ... 2000USD turned into garbage ...
After the upgrade none of them would recognize the backups I LOST ALL MY CONTACTS LITERALLY JOBLESS!!!!!!!!!!!
I wrote to "costumer care" that really doesn't care and they tried to convince me that a hardware reset will fix it , of course using NOKIAs for more than 10 years I KNOW THIS BUT IT JUST DOESNT WORKED.
So finally they say that I had to ship my units to Finland for them to check...
THEY DID NOT NEED MY PHONES TO BE SHIPPED TO FINLAND TO BE SPOILED RIGHT?
THEY SPOILED ONLINE , SO SAME AS THE "UPGRADE" WAS SENT , I SEE NO REASON TO SEND THEM BECAUSE A BIT OF LOGIC THEY JUST NEED TO RELEASE THE DOWNGRADE ...
After the OS "Upgrade"
-Not recognizing backups
-Browser not working or poorly performing and phone OVERHEATS to the point of hurt your hand
-takes about 22 minutes to reboot
-A brand new NOKIA battery will last for about 4 hours if you don't use the device (20 minutes in use)
-It turns EXTREMELY SLOW
-Battery meter shows full everytime , but after reboot it shows empty.
So ... just for you to know and consider , I do not know the new communicator N** might be good but for now I just don't feel like risking my money on them , and due to this I am probably getting another two smartphones from a brand that AT LEAST CARE A BIT FOR THE COSTUMER.
Wrote this because someone said there is no UBUNTU support ... the truth is that there is no support at all.
Sorry to step on your excitement about the E90
You can have the one that I still have if you want. -
Need some help about Win 8.1 and linux with a dual boot
Hi!
I have a Lenovo z50-70 notebook and I have a Windows 8.1 on it. (The one which was shipped with this notebook...)
My concerns are Intalling Linux as a dual boot and loosing Windows 8.1.
As I am not familiar to Win 8.1, the product key is in the ?BIOS? and there's a lot of partitions...
If I install Linux Ubuntu (latest version) as a dual boot by manually making the partitions, etc. and then if I lose my Windows 8.1 system, how can I get it back?
I've made a backup of the system to the portable hdd but I don't know can I restore it, as I have no win installation disc and I am not sure if i can restore win 8.1 from the backup by using random win 8 installation disc that I've made from the downloaded ISO (for e.g. Win 8.1 pro iso from internet)...
I need a Linux distro for developing my Android ROM but I don't want to lose that Win 8.1 OS from my notebook. So.. What should I do?Did you do a full disc backup of the C: Drive using a backup tool other than windows? If you did, then the recover of that partition will be up to your backup software.
If worse comes to worse, you can use the novo button to restore your computer to what it was like when it came from the factory. But there really is nothing to worry about. Create your new partition and just make sure that you install Linux to that partition. Make sure it is not the same size as any other partition, that way even if the Linux installer does not show the volume labels, you can tell which partition you want to install Linux in just by the size.

DUAL BOOT windows 7 and linux HELP
MASTERS
im planing to have windows 7 and linux at the same time (DUAL BOOT)
but i dont know if one key recovery still works after installation
ihave lenovo g560
i3 @ 2.53
4gb ram
any advice guys?hi botards01,
If you're planning to use linux occasionally (Ubuntu for example) and you don't want to risk losing the One Key Recovery functionality, try to install Ubuntu via Wubi as this doesn't repartition your HDD but creates a virtual disk on your current OS.
Check it out - Install Ubuntu in Windows With Wubi
Hope this helps

Dual booting pre-installed Windows 8 and Linux?
I just bought a G780 with Windows 8 pre-installed. Ideally, I would also like to install some flavor of Linux. I've been searching but not finding much info on how difficult or time-consuming this would be, or if there are any special considerations or anything. I've found some guides on dual-booting Windows 8 and Linux but they were all for installing Windows straight from a disk, not anything where it's already pre-installed, and some indicated they thought it might be problematic to use a pre-installed version of Windows. Anyway I was hoping that if anybody has done this on the G780 or even a similar laptop that you could share how it went and any difficulties you encountered. I'm open to using any Linux distro if it'll be easy to install. I would appreciate any info you could share. Thanks.
I had issues with Windows 8 as pre-installed on my G580, my employer at the time was using Windows 7 only and would not allow upgrades for security purposes. I deleted the entire drive (including hidden) knowing at some point I would re-install Windows 8 or later from retail disk when needed.
Linux can resize partitions during the install process, but be careful not to disturb the hidden partition or the windows boot loader in the process. Linux Mint is the best yet for this purpose, OpenSUSE and Fedora failed, CentOS failed and Ubuntu was not able to boot, but did not "hurt" the windows partitions.
Good luck. -

Word wrapping incorrect inside JTextPane on MAC 0.5/10.4 and Linux OS
Hello java-dev team,
In my application, I am using JTextPane as a text editor to create RTF text. The problem I observed with the JTextPane on MAC OS and Linux OS flavors (I tested on Ubuntu 8.04) is: whenever I am changing any of the text property (font color, font name, font style like bold, italic or underline) and then enter the characters without providing space, the whole word gets wrapped to the next line from the point where exactly the property change starts i.e. the new formatted text is jumped to the next line from the starting point of formatting.
My requirement is, as I am not adding any space character while changing the property, the characters should be entered in the sequence and should come to new line as per normal word-wrap rule.
Can anybody help me out in this regards with some solution as its a very urgent requirement?
Below I am also providing the sample code to check the behavior. There is no dynamic facility to change the property in the below code but I am providing the text with multiple formatting settings through code itself. To reproduce the above issue, just type the characters using keyboard in between characters with changed text properties and you can see the whole word jumping to new line.

}The same functionality works fine on Windows XP and problem is observed on MAC OS 10.4/10.5, Ubuntu 8.04. I am using jdk1.5 on both the platforms. I tested using jdk 6.0 on Ubuntu 8.04, and the problem is easily reproducible. I placed a query in the respective OS forums also but did not receive any replies. I also searched the suns bug database, but could not find any bug addressing the mentioned problem correctly. I also logged issue at bugs.sun.com and was assigned internal review ID of 1480019 for this problem.
If you need any additional information, please let me know.
Thanks in advance.

Hi All,
Just want to update that when I checked this issue with JDK1.6 on Ubuntu 8.04, I am unable to reproduce the issue. Everything works as expected. But problem continues on MAC 10.5. So can anybody help me out in coming out of this issue on MAC 10.5.
Thanks in advance.The only thing I can suggest is that you open a bug (radar) with apple ( developer.apple.com ), and then wait at least 12 months for Apple to get around to fixing it :s -
Creating network between Mac and Linux
Hello guys! I need to set up network between my iMac and Ubuntu linux. iMac is connected in internet by Airport and Fon Wifi Router witch is connected in router which is connected to adsl -modem. My pc is connected directly to router. Both computers have access to internet. Is there any easy solutions to share files with mac and linux? I don't need any webservers etc, I just want to share files.
Other question related to this, why is my mac's ip address like 192.168... and linux ip addrress is 84.250...?
Thanks allready!Though I'm not newbie with computers, I'm really confused becouse I haven't set up network like this never before.
Not a problem, no worry... we all know something somebody else doesn't and vice versa.
My linux says that my DHCP -IP is 193.210.18.18, is that related to this in any way?
Yes, if the Mac had an IP of 193.210.18.x, (but not 18 for x), then connection would be simple, but I think we must have two devices passing out IPs. What is the Mac's IP again?
http://www.helpdesk.umd.edu/topics/communication/ethernet/office/winxp/2882/
Do you have any advice where I could start looking from the right IP of my linux?

I'm not sure if its even configurable.

I'm trying to get Linux to install on my new MacMini but the monitor driver doesn't not appear to be correct. I've tried Edubuntu and Mint so far. Each time the installation will proceed until the monitor stops and goes into sleep mode because the Mini isn't sending a signal. I've tried both the analog and digital (HDMI) monitor outputs.
I know the new Mini is very new and is significantly upgraded. Has Linux not caught up yet?
The graphics card is a NVidia GeForce 320M
Does anyone have this kind of setup working?Thanks for the suggestion. The issue is that I can't get Ubuntu or Mint installed (the screen goes dark long before the install is completed) so updating the nvidia driver for Linux isn't possible. nVidia doesn't post Mac drivers so that's not an option either.
I'm trying to set this up as a triple-boot (Mac, Windows 7, and Linux). I've done this many times on other Macs but am stuck on this Mac Mini. This is a training lab and I need all of these operating systems in their native environment (not through Parallels or similar).
Thanks for your help! -
J2SE v 1.4.2_04 SDK on Linux (ubuntu) install problem
I've seen this question posted on this forum a number of times but no-one seems to know the answer. I would love an answer to this as have already spent far too much time trying to sort it out.
I am trying to install the j2me mobile development kit: J2SE v 1.4.2_04 SDK with NetBeans 3.6 Bundle, on Linux ubuntu ...
I download the file from this site ....
I follow the instructions on the site:
I do the chmod and this works ok
I type ./j2sdk-1_4_2_04-nb-3_6-bin-linux.bin ( this is the instruction from Sun)
and then get the error message:
bash: j2sdk-1_4_2_04-nb-3_6-bin-linux.bin: command not found
What's the solution? Any ideas?
thankstry :
sh jdkblahblhabl.bin

Solaris Express on Linux Ubuntu (Gutsy)
I am trying to install SDXE on my VAIO laptop. It passed the compatibility tests, so there should be no problem.
But, despite I have a 12 GB primary partition available, the installer tells that there is a problem with Linux FDisk partitions, which can not coexist with Solaris FDisk partitions.
I have read that it is possible to have a multiboot computer with Solaris/Linux(Ubuntu 7.10 in my case) and Windows.
But the installer does not go further.
Or should I get rid of my Ubuntu Linux?
thanks in advance for any advice on this.Finally, after three shots, I got Solaris in my notebook.
Now, I am struggling with WPA for my wireless network. Where does Solaris store WPA keys?
After a couple of hours, I decided to move to my router and wire my notebook :(
But it is ok. May be somebody could help me with this.
Also, is there a stand-by / hibernate option?
best regards from Lima, Peru
