How to confirm Linux distribution is 32 bit or 64 bit ?

I installed vm ware work station 6.5 on my laptop. Afterr that i install redhat 5.5 on this vm workstation.
Now i am not sure that this Linux distribution is 32 bit or 64 bit.
PLease tell me how i can confirm that .
PLease reply

Herb is right, but let me elaborate, the command returns quite a lot of information.
Here is a typical 32-bit system:
$ uname -a
Linux localhost.localdomain 2.6.18-238.5.1.0.1.el5 #1 SMP Tue Mar 1 20:34:56 EST 2011 i686 i686 i386 GNU/LinuxHere is a typical 64-bit system:
$ uname -a
Linux localhost.localdomain 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/LinuxIt is also possible to run a 32-bit kernel on a 64-bit machine, but I don't have one of those handy.

Building new Linux distribution.. where to go?

Hey guys. I am looking forward to building a Linux distribution that is made extremely custom to my ideas of how an OS should run. (I have some previous history of writing up Operating Systems in assembly language in both 16 and 32 bit.)
I have gained a bit of knowledge around how Linux operates and used Arch Linux for some time to familiar myself with some of the controls and directories in Linux. I tried using LFS (Linux from Scratch), and found that what it accomplishes is essentially a very slow way of doing the same as Arch Linux's package manager.
However I don't understand how to do a few specific things, which I think are central to building a new distribution:
1. What is the very most base required for Linux to run? With both LFS and Arch Linux, if you want to install the kernel, you have to install a whole bunch of other things, like bash, init, readline, kernel-headers, etc. as dependencies.
From what I understand however, the Linux kernel can run without most of these packages.
For example, I may want to have Linux boot up to turn on only one program (lets say a mysql server) and that's it. No bash or shell of any kind, no man pages, no utility commands like "rm" or "cd"
So, what is the very base minimum requirement for a Linux kernel? How do I isolate it from everything else? In theory if I have only the very base, it should take up less than a megabyte. (ie, I should be able to fit it on a floppy disk.)
2. How do I choose exactly what type of features I want from a Linux kernel? Slackware seems to give these general "hughsmp", "generic", "hugh", etc. versions of Linux. How do I choose any options available for Linux? ie being able to read ext2 or fat, or both.. Being able to execute ELF or a.out, or both.
To be able to include some features in Linux, for example handling TCP connections.. I might want to remove these if I am not using a network.
3. This might be a bit more advanced, but I didn't see how to do this anywhere: How do I detect which devices are connected to the computer? For example, if I want to detect what type of network card you have so that I can install the appropriate driver, what do I do? Is it just scanning "lspci" and "lsusb"? Or is there a way to do it without those programs?

i too have been investigating building a new distro (however, my ambitions are geared toward socializing/distributing both the entire development process, and the community itself. see here: http://bbs.archlinux.org/viewtopic.php?id=90970)
1) as far a i understand, the kernel requires next to nothing to "run". the kernel when finished initializing itself and the devices will launch a program called "/sbin/init" on the root device, unless otherwise specified on the kernel boot line. if the root device is not available (its on an encrypted device for example), then the kernel decompresses a temporary filesystem into ram (initramfs/ramfs), and launches "/init". that process than takes over from there; the kernel itself pretty much does nothing concerning booting the system.
the rm/cd/etc. commands are part of the GNU coreutils package... the bottom most basic tools on and GNU derived system. you can set up any kind of system you like with any mixture of apps. to make it fit in a megabyte you would need a heavily stripped kernel and no initramfs i would think.
2) all the features for the kernel are determined at compile time by the ".config" file. it's basically a tremendous list of key value pairs, in a kind of hierarchy. try "make menuconfig" or "make xconfig" with no existing .config file to see everything. you can compile many things directly into the kernel (y), or as loadable modules (m).
3) current way of device detection is thru a system called uevents/udev. i wont get into it too heavily, but uevent datagrams are fired off by the kernel containing information about devices/etc. and a userspace daemon (udevd) collects these datagrams and does appropriate things (create device nodes, whatever). im not sure as much here, but i think sysfs is created by running drivers, and has nothing/little to do with udev.

Which Linux distributions conform the linux-x86 port?

Hi,
I want to install an Oracle 10gr2 linux-x86 port to my 32 bit x86. Which linux distributions can i use? Which ones do you suggest?
Besides, Oracle doesn't have a port to use on a Solaris 10-x86 32 bit, does it?
Thank you, best regards.

http://fedora.redhat.com/ is probably the easiest distro to use for Oracle. There is a lot of documentation for it, and everything seems to work very nicely (on Fedora Core 4 at least -- I've only used XE on FC5).
Another distro that a lot of people have been happy with is SuSE linux (http://en.opensuse.org/Welcome_to_openSUSE.org). This seems to work well also, and has moderate resources in terms of documentation for Oracle.
Yet another common distro is Ubuntu / Kubuntu (http://www.kubuntu.org/). I'm not sure how much tweaking you have to do to get it to work, but it also has a fairly active community and documentation.
In terms of getting things to work the first time without hitches, use Fedora. If you want to have a little bit more control over your systems, use SuSE or Kubuntu. They each have their advantages.
Also, when first using Linux, choose your desktop environment wisely (unless this is a server). I like KDE and I hate using Gnome, but a few of my closest friends would disagree. It all depends on what you like and what you're used to. Tweak it to your liking.

Install Oracle 11gR2 Express Edition on Ubuntu Linux 11.04 (64-bit) Howto

h2. Install Oracle 11gR2 Express Edition on Ubuntu Linux 11.04 (64-bit) Howto
Version: B
Author: Dude, 24. May 2011
The following are step by step instructions how to install Oracle 11gR2 Express Edition (Beta) under Linux Ubuntu 11.04, 64-bit.
Access to the Internet is required.
The instructions cover the following additional topics:
- Converting Red Hat based Oracle XE installer to Ubuntu.
- Work-around for missing /sbin/chkconfig tool.
- Install Oracle XE into a different directory or disk volume.
- Relocate and configure the Oracle user and default login directory.
- Uninstall, reconfigure and perform first database backup.
- Notes and web links.
- Troubleshooting
h3. A) System Setup and Prerequisites
h4. A.1. System Access
You will need terminal command line, root and system console access to perform the setup tasks.
To open a Terminal at the system console:
Menu Applications > Accessories > TerminalThe following commands will enable remote ssh login with root access:
sudo apt-get install openssh-server
sudo passwd root
Verify:
ssh root@xe_server_host_nameh4. A.2. Software Prerequisites
The following is required in order to install Oracle 11gR2 XE:
sudo apt-get install alien libaio1 unixodbcThe following is not required, but it will fix backspace and arrow keys in case you prefer using the vi-editor:
sudo apt-get install vimh4. A.3. System Swap space
Minimum swap space required is 2 GB. You can increase swap space if necessary using a swap file:
To analyze current swap space and memory configuration:
sudo cat /proc/meminfo
To install a 1 GB swapfile named swapfile in /, for example:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
(this may take a while)
sudo mkswap /swapfile
sudo swapon /swapfile
sudo cp /etc/fstab /etc/fstab.orig
sudo echo '/swapfile swap swap defaults 0 0' >> /etc/fstab
Verify:
sudo swapon -a
sudo swapon -sh4. A.4. Kernel Parameters
Oracle 11g XE requires the following additional kernel parameters:
sudo nano /etc/sysctl.d/60-oracle.conf
(Enter the following)
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65000
kernel.sem=250 32000 100 128
kernel.shmmax=536870912
(Save the file)
Note: kernel.shmmax = max possible value, e.g. size of physical RAM.
Verify: sudo cat /etc/sysctl.d/60-oracle.conf
Load new kernel parameters:
sudo service procps start
Verify:
sudo sysctl -q fs.file-max
-> fs.file-max = 6815744h4. A.5. Oracle Installation Directory
The current Oracle Installation Guide uses the same directory like in previous versions: /usr/lib/oracle/xe/app/oracle/product/11.2.0/server. However, the current Beta installation uses Oracle Flexible Architecture (OFA) and installs into /u01/app/oracle/product/11.2.0/xe. Due to size limitations of Oracle XE it may not be necessary to store the installation to a specific directory or separate volume, but it is possible:
Install Oracle XE to separate disk volume:
From the system console menu: System > Administration > Disk Utility
Select "ext3" filesystem for Oracle compatibility and specify a Volume label, e.g. Oracle.
Notice the device name e.g. /dev/sdb
Get the drive UUID:
sudo blkid
e.g. /dev/sdb: UUID="d19a2d8f-da43-4802-8bdb-0703c855e23a"
Modify /etc/fstab to automatically mount the volume at system startup:
sudo cp /etc/fstab /etc/fstab.original
sudo nano /etc/fstab
(Add the following, using determined UUID, for exmple)
UUID=d19a2d8f-da43-4802-8bdb-0703c855e23a /u01 ext3 defaults,errors=remount-ro 0 1
(Save the file)
Create the mount-point, mount the new volume and set ownership and privileges:
sudo mkdir /u01
sudo mount -a
sudo chown root:root /u01
sudo chmod 755 /u01
Verify:
df -h
or restart the systemYou can also install Oracle XE into a specific directory:
Create a symbolic link to store the installation into an existing directory, for instance:
sudo mkdir /home/oracle-xe
sudo ln -s /home/oracle-xe /u01h3. C) Oracle 11g XE Download and Installation
h4. C.1. Download and convert the Installer from Red Hat to Ubuntu
Please see section E.3. to download the Oracle 11gR2 XE installer.
Select the version listed for Linux x64.
sudo unzip linux.x64_11gR2_OracleXE.zip
sudo alien --to-deb --scripts oracle-xe-11.2.0-0.5.x86_64.rpm
(This may take a while)h4. C.2. Create a special chkconfig script
The Red Hat based installer of Oracle XE 11gR2 beta relies on +/sbin/chkconfig+, which is not used in Ubuntu. The chkconfig package available for the current version of Ubuntu produces errors and my not be safe to use. Below is a simple trick to get around the problem and install Oracle XE successfully:
Create /sbin/chconfig:
sudo nano /sbin/chkconfig
(Cut and paste the following)
#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Debian by Dude
file=/etc/init.d/oracle-xe
if [[ ! `tail -n1 $file | grep INIT` ]]; then
   echo >> $file
   echo '### BEGIN INIT INFO' >> $file
   echo '# Provides:             OracleXE' >> $file
   echo '# Required-Start:       $remote_fs $syslog' >> $file
   echo '# Required-Stop:        $remote_fs $syslog' >> $file
   echo '# Default-Start:        2 3 4 5' >> $file
   echo '# Default-Stop:         0 1 6' >> $file
   echo '# Short-Description:    Oracle 11g Express Edition' >> $file
   echo '### END INIT INFO' >> $file
fi
update-rc.d oracle-xe defaults 80 01
(Save the file)
Set appropriate execute privileges:
chmod 755 /sbin/chkconfig
Note: You should remove the /sbin/chkconfig file after successful installation of Oracle XE.
h4. C.3. Install and configure Oracle XE
sudo dpkg --install ./oracle-xe_11.2.0-1.5_amd64.deb
/etc/init.d/oracle-xe configure
(This will take a while)
Remove the /sbin/chkconfig script, which is no longer needed.
sudo rm /sbin/chkconfigh4. C.4. Relocate and Configure the Oracle user login
The Oracle XE installer specifies /u01/app/oracle as the login directory for the Oracle user. Although not really necessary, the following will relocate the Oracle user $HOME to a standard location and create standard /etc/skel login files:
Exit all Oracle user sessions:
sudo /etc/init.d/oracle-xe stop
sudo kill -9 `ps -ef | grep oracle | grep -v grep | awk '{print $2}'`
sudo userdel oracle
sudo useradd -s /bin/bash -G dba -g dba -m oracle
sudo passwd oracle
Verify:
sudo id oracle
-> uid=1001(oracle) gid=1001(dba) groups=1001(dba)h4. C.5. Setup Oracle environment variables
In order to use sqlplus and other tools, the Oracle account requires certain environment variables. The following will set these variables automatically at every interactive Oracle login:
sudo echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >> /home/oracle/.bashrch4. C.6. Oracle sudo root access
It is not essential to allow the Oracle user to use sudo, but it is convenient:
usermod -G admin oracle
Verify:
id oracle
-> uid=1001(oracle) gid=1001(dba) groups=1001(dba),120(admin)
sudo su -
-> Enter Oracle account passwordh4. C.7. Oracle 11g XE Post-installation
After you install Oracle Database XE, its graphical user interface is only available from the local server, but not remotely.
The following will correct the problem if necessary:
Login as user Oracle or use:
su - oracle
sqlplus / as sysdba
At the SQL prompt, enter the following command:
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exith3. D) Unintstall, Reconfigure and Troubleshooting
h4. D.1. Uninstall Oracle 11g XE
The following will completely uninstall and remove Oracle 11g XE:
Login as user root:
sudo su -
/etc/init.d/oracle-xe stop
dpkg --purge oracle-xe
rm -r /u01/app
rm /etc/default/oracle-xe
update-rc.d -f oracle-xe removeh4. D.2. Reconfigure Oracle 11g XE
Type the following in a terminal window:
/etc/init.d/oracle-xe stop
sudo rm /etc/default/oracle-xe
/etc/init.d/oracle-xe configureh4. D.3. Enable Archivelog mode and perform a database backup
Login as user Oracle:
su - oracle

At the SQL prompt, enter the following commands:
shutdown immediate
startup mount
alter database archivelog;
alter database open;
exit
Login to system console of the Oracle user account:
Select Applications > Oracle Database 11g Express Edition > Backup Databaseh3. E) Notes
h4. E.1. Oracle 11g XE limitiations overview

Regards and best of luck!
Edited by: Dude on May 25, Version B: various corrections. chkconfig package (A.2.) not required.

even though I am admin user.Admin user is a MS Windows term, that does not apply to Linux or Unix in the same fashion.
The configuration script tells you "You must be root user to run the configure script. Login as root user and
then run the configure script."
This is most likely correct because your account is not root and does not have UID 0. What you can do is to login as root e.g. sudo su -, as the message suggest, or use "sudo /etc/init.d/oracle-xe configure", provided your account is defined in the /etc/sudoers file to perform root/admin actions.
Btw, do not modify /etc/passwd and /etc/group to give you admin privileges or try to create a another root account under a different name. That's not the way it works and usually leads to nasty problems.

How to use Linux legally for business in the US

Hello.
I am doing some research on software patents and how they inhibit businesses in the US from using FOSS.
My question is, basically, what would a business have to do in the US to use Linux in place of Windows/Mac and make sure they are not violating software patents? Violating these patents (for example, including an illegal H.264 codec in a company's system image so that video can be played by employees) present a serious liability to US businesses and could potentially discourage them from abandoning a proprietary OS for a free one.
One portion (of many) of this discussion I do not understand is how does one guarantee their system is clean of illegal codecs? For example, assume if one used his/her package manager to delete any codec-related packages he/she could find. If this person used a web browser to navigate to a website that included in-page H.264 videos or sound effects encoded using MP3, would this content merely not function (meaning, the person would be legally safe but unable to play the content)? Or do web browsers have these illegal codecs built in? I don't understand how website programming works enough to know the answer to this particular question.
I would appreciate any insight on this issue (and/or any thoughts you might have on this subject).
Thank you for your time.

See distro's to avoid here if you are in the US:
http://www.gnu.org/distros/common-distros.html
And, linked from that page, see ones that should be safer:
http://www.gnu.org/distros/free-distros.html
With Parbola:
https://parabolagnulinux.org/
Being Free and based on Arch.
Now, the problem, completely free is very picky about the hardware it will run on so you will want to procure hardware specifically built to run under a Free system without issues. Licensed distributables you can get away with using, for example: Adobe Flash Player. Just accept the license agreement and you should be good to go. The minefield is that somewhere in even the Free code there could be a patent lying in wait. Something that someone in the US patented and the Free systems programmers were not aware of it. This is an issue in the US because commercial Operating Systems such as Windows will indemnify their users against patent infringement. On Free systems however you, the business using them, could end up being on the hook for significant damages.
The reason a completely Free system is very picky about what hardware it will run on is because all those binary blobs in common Linux distributions contain code that just makes stuff work. Without that you have to make absolutely sure that what you have will work with just Free software.

Attention! About problems with Oracle 8.1.6 on newer Linux distributions!!

Hello all, I've just got some feedback from a helful person at http://www.crunge.com/ about the problems concerning RedHat Linux 7.0 and Oracle 8.1.6, this MAY apply to other newer linux distributions.
I've tried, without luck, to install Oracle on RedHat 7.0 and Slackware 7 (the newest one), and it would not install properly, kept stopping right about when the database initialization started at 80% finished install procedure. Sp i wrote them a mail, not expecting an answer really, but I did got an answer, and below is what the person said;
Thanks for the feedback.
Oracle 8.1.6 does not work under Red Hat Linux 7. Yes, that's the problem
that I mentioned in the doc--you get to 80% and the DBCA crashes and the
Oracle executables die.
I've heard, but I haven't tried it myself, that if you install the latest
glibc errata (2.1.94) then the DBCA completes but the Oracle executables
still die. The DBCA problem was apparently a Java issue that is fixed in
the errata. But you're still out of luck since the exes won't work.
It might appear that this is a problem with Red Hat Linux 7. But it appears
that it is a problem with some assumptions that Oracle made, assumptions
that worked with glibc 2.1.3 (the C library included with RHL 6.2) but which
prove false with later glibc versions. As other Linux distributions adopt
the new glibc Oracle will fail to work on them as well.
The best advice I can give at this point is to install and run Oracle on
Red Hat Linux 6.2. Hopefully Oracle will address the glibc issues with the
8.1.7 release.
Chris
p.s. Do not construe this
as an official Red Hat response; I merely forwarded your e-mail from my
home account. This response and the web pages I put up are mine.
So i guess one sollution to the problem is to try a bit older version of the linux you are having problems with (i tried it on RH 6.1 and it worked like a dream).
Another solution can be to wait it out to check and see if Oracle put a fix out here on technet...?
Hope this helps people bogged down in fustration.

OK, so i followed your instructions to the letter (several times), sure I get past the 80% bug but now I have new erros coming up , -"Error in invoking target install of makefile /usr/oracle/sqlplus/lib/ins_sqlplus.mk". I get a whole series of these errors for various mk files. These errors apear during the link phase of the install, prior to the glibc workaround I was not getting this. I am a newbie to Linux and trying to give it a serious go but so far I have had little luck
Any help appreciated.

How can use linux in my macbook?

how can use linux in my macbook?

You can use various distributions of Linux either by running them under Boot Camp, or in a virtualized environment such as Parallels or VMWare's Fusion. Note that you may have to try several different distros until you find one that works. I settled on Ubuntu running under Parallels.
Best of luck.

SCN scheme 2but i have crosschecked the same in oracle metalink 151496.1
and i got to know that
The error is reported by Oracle during allocation of the SGA and will happen
in cases where the kernel parameter SHMMAX/SHM_MAX is not set high enough.
The SHMMAX kernel parameter decides the maximum size of a shared memory segment
that can be allocated in the system. Since Oracle implements SGA using shared
memory, this parameter should be set appropriately. The value of the SHMMAX
kernel parameter should be higher than the maximum of SGA sizes of the Oracle
instances used in the server. In cases where the SHMMAX is smaller than the SGA
size, Oracle tries to fit the entire SGA into a single shared memory segment,
which will fail, and you will see the warning message in the alert.log.
The recommended value for this parameter is 4294967295 (4 GB), or the size of
physical memory, or half the size of physical memory, depending on platform.
Setting the SHMMAX to recommended value in the kernel parameter configuration
file and rebooting the server will get rid of the warning messages. See the
platform specific Oracle installation guide for detailed information on how to
modify the SHMMAX/SHM_MAX kernel parameter.but i had also set the value half of physical memory i.e 4gb but still i am getting the same error

How do you open Firefox in 32 bit?

Hi
I'm using Win7 64 bit & I need to open Firefox in 32 bit. A plugin I need doesn't like 64 bit.
Everything I have found so far pertains to Mac.
How can I open Firefox in 32 bit?
Thanks

Thanks for responding! I am trying to use Sibelius Scorch plugin which is a 32 bit plugin. Every post I have seen on this says that I have to run Firefox in 32 bit for it to work.
I have another pc that is XP 32 bit & it works fine in Firefox, which would confirm what I had read. Any ideas as to how I can use this plugin on my 64 bit OS with Firefox?
Thanks again!

How to install Linux on Sun Blade 2000

hi,all.
There is a sun blade 2000 workstation in our lab.And my teacher ask me to install a Linux OS instead of the Solaris8 which is preinstalled in this machine.This thing is very difficult to me,for I am not only a new to Linux,but also a totally freshman to Sun OS and its Hardware.
I have only installed a Fedora 11 in my x86 machine.But i dont know how the sparc architecture working and how to start my installation,even include how and where to boot from installation CD.
Please tell me what the step of installation and how to do.Furthemore,please recommend a Linux distribution suitable for the blade 2000.
Thank you very much.

If you never ever worked with Linux then Debian is not really the OS you want to choice first, don't get me wrong its very good, but i think Ubuntu which is based on it is more user friendly
Ubuntu has also a Sparc version and a forum for Sun Sparc users.
http://ubuntuforums.org/forumdisplay.php?f=146
some issues related to the type of server you have : http://ubuntuforums.org/showthread.php?t=588088
Then you have also the question if you want to install the server edition or the desktop version?
for example dapper server is available here: http://cdimage.ubuntu.com/ubuntu-server/dapper/daily/current/dapper-server-sparc.iso

How to make linux bootable off a usb stick on mac

Guys i was wondering how to make linux bootable off a usb stick on mac, since i dont have a optical drive in my mac, plus i need it for university

I have the same question, but parsed differently. What people have tried answering here is:
how to (make linux (bootable off a usb stick on mac))
What I'm trying to find is:
how to make ((linux bootable off a usb stick) on mac)
That is, I don't want to boot from the usb stick on my mac; I want to write an ISO to a usb stick that's plugged into my Macbook Pro (Mavericks), then carry the stick to a different machine (several discarded Windows boxes in fact), plug it in there, and watch it boot on that machine. I've done a bit of googling, but everything I find talks about making USB drives with content that can be booted on a Mac. What I'm wondering is if it's possible to write to use my Mac to write bootable USB gadgets that work on other machines that aren't running OSX software.
Anyone know if this is discussed anywhere? If not, what's the right forum to ask it on? And how do I ask it so that I don't get yet another explanation of how to make something that will boot on my Mac?
I have several linux ISOs waiting. Actually, I could do the job on one of several available linux boxes. But I'd like to do it on my portable laptop, which at the moment is this Macbook Pro.

Javascript Adobe Reader problem in some linux distributions

Adobe Reader doesn't execute initial javascript code of 3D scene in pdf document. With friends we've tested several linux distributions, namely CentOS, Ubuntu, Arch Linux, Mandriva, OpenSUSE. Also several Adobe Reader versions like 9.4.6 or 9.1. No luck. For some reason though, it works fine in Fedora (with exactly the same Adobe Reader). Here is an example pdf for test: http://www.2shared.com/document/LIbyWm_ … _dice.html . Just open the mysterious_dice.pdf and you should see a rotating dice. If you dont, javascript wasn't executed properly (it should be easy to check in Windows 7/XP or Fedora).
We thought that something is wrong in Reader settings (like disabled javascript), but javascript was always allowed. Then that maybe it is linux Adobe Reader bug, but again, why does it work in Fedora? So maybe some package(s) or something.
Another example is the Asymptote application, which uses javascript at the beginning for some scene settings (lights, camera position, etc) and especially with orthographic projection this problem shows up. More about this here: http://sourceforge.net/projects/asympto … ic/4021157.
Any idea what might be wrong with this? I will just add that javascript later on works, only the initial code is ignored. Thanks for any suggestion.

Interesting, just to be sure, was your dice spinning around? If it was, then it really works. My friend with Arch i686 just tried it with Adobe Reader 9.4.2, same settings and the dice was static. He provided also screenshot to show how it looks on his system together with some info:

Linux distribution

Hello,
i start to work with Flex Data Service and i also have to
install a server under linux. I wonder if there is a linux
distribution for which we know that FDS works well.
Thanks!

Fedora 20 is newly released and is having troubles while being installed in normal process
so go ahead install it in basic graphics mode which u can find in troubleshooting.
after the installation download and install amd catalyst driver from the official amd site it's a run file so just chmod 777 it and ./execute it in super user mode
you might find the driver installed with errors without restarting the system simply follow the steps
so follow these steps
open up a terminal in super user mode and
$ cd /lib/modules/fglrx
$ vi /build_mod/kcl_acpi.c
              press - esc button and " :set number "
              go to line 999 edit the data type in the line
         from     ((acpi_table_handler)handler)(hdr);      to   ((acpi_tbl_table_handler)handler)(hdr);
         now execute the following commands to remove file by driver execution earlier
$ rm /etc/X11/xorg.conf
$ rm /etc/modprobe.d/blacklist-fglrx.conf
the next two are optional if in case u execute them please make sure it is lib64 or lib86 basing on which bit os u are using in the /usr folder
$ rm /usr/lib64/xorg/modules/amdxmm.so
$ rm /usr/lib64/xorg/modules/drivers/fglrx_drv.so
and now follow these instructions
$ cd /lib/modules/fglrx/build_mod
$ ./make.sh
$ cd..
$ ./make_install_sh
this is it now reboot your system and search for amd catalyst control center and adjust setting so as to maximize your battery...
same steps even with fedora 19 which is what i am on right now
pass on the info around as i got this information after putting together many research points i found out to tackle this problem in goolgle search

Please help me identify this Linux distribution

Hi!
I recently stumbled upon a netbook Linux distribution which where booting very fast but I somehow can't find it again. They had a link to a youtube video on the distros frontpage showing it boot in only 7 seconds (I think). It had a typical netbook interface with taps on the left for stuff like media, internet, etc. Immediately after boot it showed a internet connection tool making it easy to connect to a wireless network. I think the deafult color scheme was something with blue/black.
I've looked trough all the top 100 distros on distrowatch and I've been searching around the net but i can't find this distro. If someone know what distro it is I'd be very happy to hear it

Not Jolicloud either. It was looking a bit more "homemade" than Jolicloud and Xandros.
It isn't any of these either: Ubuntu Netbook Remix, EasyPeasy and MeeGo.
EDIT: I finally found the video I was talking about on YouTube. The distro is xPUD
