Configuration instructions 2008/07

Kudos to PCMan for adding detailed instructions on proper xorg.conf troubleshooting, but I'm wondering how necessary it is. If users run hwd -x to generate their configs (instead of Xorg -configure) all of the necessary items are added to xorg.conf automatically, making the bulk of the new information unnecessary.

Is there a reason we don't instruct users to run hwd to generate the xorg.conf files?

If you are sure hwd -x is the best way to do this, then you should change the wiki to recommend this option. I am not sure, since I'm new with linux and so forth.

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, 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 [1]. (flashplugin, 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 notes

KMS on r5xx not works with linux only if libdrm, libgl, mesa, xf86-video-ati - all installed from git.
