for the rt kernel and other audio apps:

Repositories
We have a total of three binary “repos” on our server. For now only our testing repository is really active, but we recommend adding all of them to /etc/pacman.conf (replace i686 with x86_64 for 64-bit):

# tried and tested packages
[archaudio-stable]
Server = http://repos.archaudio.org/stable/i686

# these are..for testing?

you, I just got my ATI woking with compiz but I've had issues with drivers. You need the xf86-video-ati driver. it's in one of the 3 main arch repos.. Once you know how to install Arch, it's easier than most distros...

Wow, thanks a lot. I guess that saves me a lot of compiling.
Still, when I install and boot kernel26rt, xorg won't start and I get several screens full of "WARNING: GdmLocalDisplayFactory: maximum number of X display failures reached..."

That's the driver I was first using when I tried my ATI card without success. Actually I was quite happy with my onboard Intel graphics until the above mentioned problem came up.

[funkmuscle]

do a sudo pacman -Syyu
then sudo pacman -S xf86-video-ati

That's all I use. the Intel may need to compile the driver for rt support.
I have both the rt and regular kernel working with xf86-video-ati...
the latest xf86-video-ati gave me compiz and KMS...but I've been using it for sometime now..

With "kernel26-ice" I'm not sure how to activate the rt patch)
But I'll keep working on it. It seems well worth the effort.

You have to change the PKGBUILD file

Code: Select all

### User/Environment defined variables
bfs_scheduler=${bfs_scheduler:-0}
keep_source_code=${keep_source_code:-0}
menuconfig=${menuconfig:-0}
realtime_patch=${realtime_patch:-1}
use_config_gz=${use_config_gz:-0}
enable_reiser4=${enable_reiser4:-0}
###

Put 1 instead of 0 to the realtime_patch option. Also you probably want to do the menuconfig and change some options of the kernel making it suitable for audio computer. There was some tips in the arch linux wiki pro audio page. Linuxmusicians wiki also helps http://wiki.linuxmusicians.com/doku.php ... d79bd848bf

I recommend that you read about the PKGBUILDS and AUR from arch wiki to get the basic idea how they work.

this is the latest ice-rt kernel from AUR...
http://aur.archlinux.org/packages.php?ID=31893

first install yaourt or auget:

yaourt -S kernel26-rt-ice
or
aurget -i kernel26-rt-ice

compile.......

It's working !!! After putting in the ati card and installing xf86-video-ati everything is fine now even with kernel26rt (was my mistake not to trust ati after it hadn't worked with arch in my other machine). Still doesn't explain why the intel graphics wouldn't work with rt even after compiling xf86-video-intel-newest from aur.
Nevermind, it's great this way and I now get zero xruns (in a quick test with jack and rosegarden) as opposed to before with the standard kernel. Also, the FPS rate of glxgears has almost doubled with rt kernel - Is this normal?
All this is with kernel26rt. I might try ice-rt soon too (again). Any obvious advantages?
Thanks a lot for your help guys. I'm very pleased at the moment

right on man!! good to hear that...
make sure you install and run rtirq for better performance and hdparm or sdparm for fine tuning the hard drives..

If only more were willing to try arch, they would be happy as were are... Been using it for years..

Two questions about Arch:

1) so in Arch I don't need a special RT-Kernel?
http://wiki.archlinux.org/index.php/ProAudio


2) there are 3 versions. the 32 bit, the 64 bit and the dual-core
I have a dual-core 64-bit processor......so choose I the second or third option?

choose dual-core if your pc is.... double check that it is 64 bit... I'm pretty sure it is.
I can do audio recording without the rt kernel and no xruns but I use the rt because I use the rtirq which helps big time with IR files(jc_gui, guitarix, etc..)

Not necessarily it seems. I can run JACK with the normal kernel and my default sound card pretty well. The Latency is pretty high, but I only do that with I'm mastering and just need to hook up some plugins and I'm not using outside gear. I still like the RT kernel though. I can get some pretty low latencies with my 18CH USB card (Edirol M-16DX). Depends on what you do.

The "Dual Arch" image has both the i686 and the x86_64 environments on them. It isn't a Dual Core specific image. The x86_64 will support multiple cores (4 in my case) just fine. If you want to run 64bit with both cores then the x86_64 image is the one you want.

Good Luck!

ahhh, ok. I thought the "Dual Arch" was some kind of dual-core-version...thanks a lot

I will now go on the Arch-jorney, too

Careful, you might not come back!

hopfully, man....i'm tired of reinstalling OSs....i hope this will be my last installation for the next years

I have installed Arch for a couple of times and I must say I would recommend using ArchBang even though it installs some stuff I dont need. It's still very lightweight. Ofcourse by installing plain Arch you might learn a bit more about the system and can install only what you need, but I will use ArchBang for now on if I need to reinstall since I would use openbox anyways.

I almost did that, too, since I use fluxbox, too.....but the "alpha"-state didn't sound good to me.
Must say it is a lot of work to get everything in Arch working, but i think it will be worth it.
