Hi,
I own an ATI Radeon X1800XT 512MB. When I bought it, it was kinda the
flagship GPU. But sad to say, the ATI Linux experience has been very
frustrating.
1. Installing and configuring xorg.conf with fglrx is a big headache.
aticonfig doesnt set all options for me, and some I have to set Manually.
2. Surprisingly, some 7 drivers from 8.33.6 to 8.38.6 never worked on my card.
I used to get a hung comp with Xorg eating 100% CPU. So, I was stuck on
kernel 2.6.18 and finally got 2.6.20 working with a patch published by
Phoronix for 8.32.5. We filed many bug reports as the problem was being faced
by many ATI users. Although ATI never acknowledged our report, the problem
was mysteriously fixed in 8.39.4.
3. All four driver versions since then have been a major disappointment.
8.39.4 just got my card running. 8.40.4 was fine but with broken Xv, and
Textured Video. (Tearing of video)
4. 8.41.7 (Much touted new OpenGL codebase driver) gave me slow crappy 2D
performance. Talk of slow window refreshing and minimizing (even with the
normal X11 (no fancy XGL) ). Video tearing was also rampant.
5. 8.42.4 got me AIGLX. Beryl runs fine. But with very low framerates. Video
playback is fine now (Xv no longer tears video). But surprisingly, I cant
change any 3D settings in this driver in the Catalyst Control Centre. Compiz
fusion has never worked for me with this driver, and I have slow scrolling
problems in Firefox, windows with AIGLX enabled. So for now back to 8.40.4
and XGL.
Just waiting for the open source RadeonHD to mature. I am tired of AMD's
promises and continually disappointing fglrx releases. So stick with Nvidia
for now.
