I've tried both Sun and Open-source Java. No difference. Been following the wiki pretty closely. Everything else having to do with graphics and X seems to work fine. Just let me know if more information is needed.

Actually, the proprietary driver is NOT installed on my Ubuntu, and I'm pretty sure my card is too old to be supported by that driver. I've reinstalled arch, because idk what I was messing up, bouncing between the two drivers. The open source driver is installed now. Problem persists. If I run glxgears, the framerate in Ubuntu is at least double the speed in Arch.
Idk what I'm missing. If I've not posted some information I should have, sorry. If I've not done something obvious, sorry. Just tell me what I need to do.

Pacman slow in Arch, but fast in Ubuntu

Hello
I searched among Pacman related topics on this forum, but I didn't find anything related to problem I have. It takes Pacman very long time to download many small files. Bandwidth isn't the case, but the time it takes Pacman to start downloading next package. My average ping to http://mir.archlinux.fr is about 70ms. When Pacman completes downloading packageN there's a few second lag till it will start downloading packageN+1. There's no such lag when I run Arch Linux in Ubuntu under KVM and using the same mirror.
PS. I have ipv6 disabled.

Arch linux for Ubuntu users

Hello everyone,
When using Synaptic on Ubuntu it usually sets everything up for you so all the installed software tends to work out of the box without any need to change around configuration. Is the package manager in Arch Linux as integrated as the one from Ubuntu?
Thanks
Frank

I'm new to the linux scene (about 1 month now). My most used distro (and my fallback if I mess up another distro on a seperate partition) was Ubuntu, until I figured out the basics of Arch. After this enlightenment, I find Arch to be much easier to work with in terms of customizing apps, having the right libraries I want, and to just do daily functions. I love to always check for updates to the system. Ever notice in ubuntu there are about 30 repositories you have to sync with? In Arch there are the 3 basic repositories (extra, core, community) and multilib if you are on 64bit. Working with pacman is much more efficient and controlled than apt-get imho.
One thing I hated with apt-get is that you add in 3rd party PPAs that are slow. With Arch and its pacman + yaourt(aur) there is really no need for these 3rd party repositories as everything you can imagine is probably available in official repositories or built by the community. Go check out https://aur.archlinux.org/ this is one of the coolest community made pool of apps around.
As mentioned before, the pacman doesn't hold your hands so be prepared to google and learn what some packages do. For example, I am running gnome and install a KDE app called amarok. Pacman will install everything (including KDE and qt libs) to get amarok started. However, the only things it doesn't install (but it does tell you what) is extra depencies.
Optional dependencies for amarok
libgpod: support for Apple iPod audio devices
libmtp: support for portable media devices
loudmouth: backend needed by mp3tunes for syncing
ifuse: support for Apple iPod Touch and iPhone
So, basically I just read through pacman's output, and either google or make a decision on what is needed. This way my system is controlled tightly and I know more about the system. In the future if I buy an ipod and want to sync, I'll remember there are some optional depencies available for this. I can type "pacman -Qi amarok" and it will show me what it depends on as well as optional depencies.
Sorry for going on for so long but you get the point.

[solved] Wireless Slow in Arch

I've noticed that my wireless has slowed down.
I ran a speed test and am recieving download speeds of about 0.7...whereas my housemates are getting around 15-20mb
I've realised that this has happened each time that ive installed Arch, where suddenly my internet becomes slow.
I'm using rt2870 drivers for my ew7717un usb.
My wireless has been working fine beforehand but is slow all of a sudden and i dont remember changing anything. Im using KDE also.
Please can you help me...and any advice regarding posting logs, extra details etc.

Nevermind, for the moment its solved.
I managed to get it working using Networkmanager...rather than Wicd which i was using.

Wireless buggy in Arch, works in Ubuntu. Help me find the cause.

Hello,
I've just installed Arch on an old laptop. After connecting to a wireless network, everything works for usually under a minute, then the connection (to the access point) drops.
The wireless driver is ipw2200, and there are lots of bug reports about frequent disconnects with it. The usual advice is to turn off power management (which doesn't help) or to downgrade to version 3.0 (which I haven't figured out how to do).
What confuses me is that wireless works fine (out of the box) when using an Ubuntu (12.04) live CD. I don't know enough to find where the Arch and Ubuntu setups differ, so I was hoping to be walked through the process.
Other information whose relevance I can't judge:
The Arch install is without a desktop environment. I've tried using wifi-menu and wicd for network management, and the problem exists with both. In the wicd settings, the WPA supplicant driver is by default wext and none of the other options (nl80211, ralink_legacy) work, and neither backend (external, ioctl) helps.
The output of "lspci | grep Network" is:
06:05.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
The laptop is Fujitsu Siemens s7020. Kernel is 3.5.6, i686.
Some of the output of iwconfig (I'm typing this by hand, which is why I didn't paste all of it. I could if it'd be useful):
Mode:Managed, RTS thr:off, Fragment thr:off, Power Management:off, Link Quality=62/100, Rx invalid nwid:0, Rx invalid crypt:183, Rx invalid frag:0, Tx excessive retries:0, Invalid mist:2, Missed beacon:19

MBP suddenly extremely slow, checks return fine - anything else?

Hi there,
The issue: MBP had been working fine but all of a sudden it is frustratingly slow to the point it is near unusable. This literally happened overnight - it was fine, then I woke up to use the laptop and these issues occured. 95% of requests (clicking on something) are followed by a few sections of nothing, then the spinning pinwheel for anywhere from 5-30 seconds, this also happens when scrolling or opening web pages or writing things in word or on the web. I have just timed my boot up at 3.23mins and I have nothing that opens on boot up.
Spec: I am using an MBP mid 2012 model, 2.5Ghz Intel Core i5 processor, 4GB 1600MHz DDR3 memory running OS X Lion 10.7.5. The 500GB hard drive has 323.13GB free space and 2.69GB free memory.
So far: I have removed any external additions, unplugged anything that was plugged in, disabled my firewall and turned off WI-FI - this didn't help. I have checked the CPU usage and the computer is having issues even when running at 95% idle. I just did the AHT which reported no issues and checked the HD in disk utility - it gave me both the brand, model, size of the HD which as far as I know means theres no hard drive issue (correct me if I am wrong). I also just finished backing up all my files on time machine which took about 2 days.
I know there have been similar threads which is where I got most of my troubleshooting noted above from. I am aware that it would also seem logical to take the laptop to get checked out at the apple store, however I am an international student at college in quite a remote area - the nearest apple store is at least 90 minutes away and I am unable to drive cars in the US. We do have a computer store on campus who have technicians however they charge regardless of if they can help - I am wondering if there is anything else I can do myself to fix the issues, or at least determine what might be causing them, before taking the laptop in to be seen as a last resort.
Any help at all would be greatly appreicated.
Thanks.
P.s, apologies for the length of this, I have tried to be as in-depth as possible to avoid any time wasted asking simple questions etc.

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. It does nothing but produce human-readable data about the state of your computer. However, you need to be cautious about running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only run the test in safe mode, proceed anyway.
If you have more than one user, and the affected user is not an administrator, then please run the script twice: once while logged in as the affected user, and once as an administrator. The results may be different. The administrator is the user that is created automatically on a new computer when you start it for the first time. If you can't log in as an administrator, just run the script as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the script will run anyway, but it will produce less information. In most cases, the difference is not important, so don't worry about it.
The script may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "[Process completed]" to appear in the Terminal window.
You can then quit Terminal. The output of the script will have been copied to the Clipboard automatically. All you have to do is paste into a reply to this message by pressing command-V again. If any personal information, such as your name or email address, appears in the output, anonymize it before posting. Usually that won't be necessary. Please don't copy anything from the Terminal window.
When you post the output, you might see in your browser the message, "You have included content in your post that is not permitted."

WiFI extremely slow in Arch

I have a new install of Arch after deciding to give it a go after 6 or 7 years on Gentoo.
The only problem I am experiencing is extremely slow internet. 1.58Mbps vs 31Mbps previously in Gentoo.
Google seems to indicate a lot of people have similar issues with Arch, but having followed the Wiki to the letter and not finding any solutions on Google I am stuck at where to start.
iw dev

Please let me know what logs to upload, any assistance appreciated. I will continue to search myself.

If you are using a USB WiFi device that can potentially change names with different ports, it would probably make sense to either create a persistent name for that particular piece of hardware, or go back to the old naming scheme if you don't have another wireless card. The idea of these crazy names is that if you have two wireless cards, two ethernet cards, or even an ethernet card and a broadcom wireless card (which also uses the eth* namespace), you will never know which will be 0 and which will be 1. But if you tell the system what to name them, then you can at least have your netctl service run on a given interface name and know what it is going to be.
Having said all that, you should also be aware that other network management solutions deal with changing interface names much better then netctl. Netctl needs the interface name to be specified in the profile, so if it changes you are kind sh*t out of luck until you make the manual changes necessary.
To see if you have multiple network management services trying to handle things, run "systemctl --type=service" to see all the services you have going. If you see more than one that should be handling the network (for example, if you enabled [email protected] during setup) then you need to figure out which single management solution is going to best fit your use case and go with that one only. Most commonly, people still ahve dhcpcd.service or dhcpcd@<interface>.service around. But it is also not uncommon to see people with netctl-ifplugd@<interface>.service running along with netctl-auto@<interface> at the same time, which will also cause issues.

Arch linux on ubuntu?

I was always wondering, why is there an arch linux sub-forum on the ubuntu forum?

molom wrote:We should have an Ubuntu sub-forum on the Arch Linux forums
Hey that's not a bad idea, we can do that and then organize bets like 'how long will it take before someone posts something there' , etc...
A fraction of the money involved goes to Arch of course

Conky font differences under Arch compared to Ubuntu [SOLVED]

I'm using the same basic .conkyrc when I'm booted into Arch as I do when I'm booted Ubuntu. For some reason, the one under Ubuntu looks different font-wise. In the screenshot below, Arch has the light blue background while Ubuntu has the slate colored one. Anyone know what might be causing this?
Here is the first part of the ~/.conkyrc

Here is the output:
$ xdpyinfo | grep dots
resolution: 90x88 dots per inch
I'm using Gnome but can't seem to locate a section to change my dpi. I'm using the nvidia driver (8800GS) but didn't see an area under nvidia-settings to change it either. I tried that xrandr line you proposed, upon restarting gdm, the setting didn't take:
$ xdpyinfo | grep dots
resolution: 90x88 dots per inch
Here is my ~/.xinitrc
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
exec gnome-session
xrandr --screen 0 --dpi 96x96
Thanks!

Newbie consulting about migration to Arch Linux from Ubuntu

I am using Ubuntu until I find Arch Linux, and I feel I quite agree with its principle of simplicity. I am considering a migration to Arch Linux.
The two major aspects I am thinking over are NTFS support and Chinese support.
As for NTFS, I need a system which has the capability to both read and write NTFS partitions, and stability is quite important for me. I cannot afford any data loss! With Ubuntu, I have never suffered a data loss from NTFS partitions.
As for Chinese, I do not care about the UI language. Usually I use US English. But I need the system to display Chinese and allow me to input Chinese.
Does Arch Linux meet my requirements? Or is it possible to configure it to have those capabilities?
Thank you! And sorry for my poor English.

ntfs-3g takes care of NTFS support. It's quite stable here, and I reckon Ubuntu uses it as well.
From my experiences with writing Japanese, I'd say that Arch is definitely able display Chinese as well. Writing chinese Characters shouldn't be that difficult either, given the fact that all Linux packages are basically the same. It's also possible to display and write Chinese characters in a console.
As for stability, I never had any problems, though it's in rare cases necessary to refer to the homepage before updating system-critical packages. I'd also update at least once a week if I were you.
Thank you!
The stability I stated mainly refers to the stability of ntfs-3g.

Uncyclopedia Arch Linux Entry - Ubuntu Noobs

Seeing as Arch's community has a relatively significant population of (ex?) Ubuntu Noobs, I felt the urge to include a little splurge about it on Uncylopedia. The fact that I wrote it is a bit ironic, because I am an ex Ubuntu noob myself (used it for almost a year before I called it quits).
I'm posting this thread to see if my statements actually resonate with the Arch community or not really - and if anyone has serious objections to it I'll remove it. But hey, it's just a joke...
http://uncyclopedia.org/wiki/Archlinux#Ubuntu_Noobs
edit: I doubt this is worth noting, but this is my first time using uncyclopedia so I hope I really hope you like it.

Methinks you don't quite yet have the right mindset to contribute to Uncyclopedia.

Why gcc compile so slow on Arch?

That's a big project, it takes about 30 mins compile by "make -j4" on Ubuntu.
Compare to Ubuntu, Arch take more 20 mins compile time!
The only different thing is Arch installed in SSD (project code too), Ubuntu in traditional disk.
Due to the project can't compile with 64bit system, Arch and Ubuntu all is 32bit OS.
The Arch already installed PAE kernel from AUR.
Anyone can help? Thanks in advance and sorry for my bad English.

karol wrote:Are you compiling using the same processor? Are you doing anything else at the same time apart from compiling on this computer?
On Arch, are you compiling using 'make -j4' or are you using makepkg and a PKGBUILD?
I'm quit sure using 'make -j4' both on Ubuntu and Arch, and of course the same computer.
I'm not using makepkg because we don't support yet currently .
I've tried several times to compare build time, not occasionally.
The project's build system is CMake, I don't think cmake is the problem.

Web pages loading unusually slow. Load fine in alt browser

Web pages on numerous sites very slow to load. Even coming to Firefox to report. Including some pages coming up error as if there is no connection. I tried alternative browser and the pages load fine. I could have stayed on that browser but ff has always been my goto.
I have a nexus 7 (suppose I should say 1st gen now) running 4.3.

There are some problems with the new Android version (4.3), they should be fixed very soon (12-24 weeks), there is a solution, use firefox nightly, the superbeta version of firefox 26.
DOWNLOAD FROM: nightly.mozilla.org
Does the nightly work better?

Minecraft slow in Arch, fine in Ubuntu
