Forking this article for proprietary
Cleaned up some info today and noticed this article is really getting unruly. I propose that we fork the proprietary portion to its own article, such as "ATI Catalyst". Considering that the fglrx is now absolutely unsupported by Arch Linux, it would help make this article much less daunting to newcomers.

- I wholly agree.

EXA and Adobe Flash performance
I noticed that enabling
Option "AccelMethod" "EXA"
as mentioned under "Performance tuning" lead to significantly worse Flash performance. This was using extra/flashplugin 10.0.22.87-1, aur/firefox-beta 3.5rc2-1 and extra/xf86-video-ati 6.12.2-2. My card (ATI Radeon 9550) uses the RV350 chipset, hence it is a bit dated.
If this isn't just a local phenomena, perhaps it should be mentioned?
I don't know. I disabled EXA, and got even worse Flash performance, according to a flash benchmark test I found at Snails Animation . (flashplugin 10.0.32.18-1.1, firefox 3.5.3-1, xf86-video-ati 6.12.2-2.) Same card and chipset, though. --Rataxes 16:38, 15 September 2009 (EDT)
KMS on r5xx not works with linux 126.96.36.199. only if libdrm, libgl, mesa, xf86-video-ati - all installed from git.
KMS seems to be enabled by default on r5xx with latest packages from arch. Should all those messages about it being unsupported be removed? TheCycoONE
I don't know how others feel about this, but my preferred setup is to put options radeon modeset=1 in modprobe.conf and then to include modprobe.con along with the radeon module in mkinitcpio.conf. This way KMS is enabled once for both early and late start. Also, in the event of problems, radeon.modeset=1 can still be added as a kernel option to the bootloader. --piezoelectric
Added a note in the KMS setup section about where to locate libgl and ati-dri in the ABS. Hope it helps. I was banging my head on that one for a week. Wriggary 20:04, 29 January 2010 (EST)
Driver ati or radeon
I just did the tutorial installing:
pacman -S xf86-video-ati libgl ati-dri
I could only get it working by changing in xorg.conf:
as the tutorial stated. I have no idea why/how, but maybe it'll help people reading it here.
