(From update of attachment 6744)
Short summary: r300 is stable when forced into PCI mode via "BusType" option,
otherwise completely and randomly freezes the system when "glx" module is
loaded, but not when "dri" module is enabled.
--
Same thing here. Using an older r300 driver (downloaded from cvs in July) in
AGP mode, it just happened when the GLX module was loaded. 2D acceleration
worked (XAA, EXA) and the system didn't freeze (dri and drm modules were
enabled in xorg.conf).
After the latest driver update (from git), DRI doesn't work (disabled) when the
driver uses AGP mode. However, when I force the driver into PCI mode via the
"BusType" "PCI" option, DRI and GLX work (though slow, I only get 1000 fps in
glxgears instead of >=2000 fps). This is on a radeon 9500 Pro (4E44, it says
ATI Radeon 9700 Pro ND AGP) 128MB.
The various AGP options for the driver (and I've tried everything) won't make
any difference. X won't even start with AGPFastWrite option enabled (reboot
required).
Although PCI mode is not fast, at least I have a working system with 3D
acceleration and transparency fx etc.
Btw: Two glxgears work, but a third will cause a "Ran out of GART memory!
Please consider adjusting GARTSize option." How can I do that? And xscreensaver
sometimes has display errors (I guess memory is not enough, I'm using MergedFB)
but doesn't crash.
The r300 driver also seems to do something strange to my TFT screen: Gamma? is
too high, so that background pictures with very light grey actually are
completely white. On the second monitor (CRT), everything's ok. Changing gamma
with xgamma doesn't help though, I can't see the light grey colours. I guess
there's something wrong with the signal processing? Maybe I should file an
extra bug report about this? It would be nice anyway if different gamma
settings could be chosen for the other monitor.
The radeon works fine in windows xp (although the display gets corrupted after
resuming from standby or hibernation) with catalyst drivers. I can play games
for hours, there are no stability problems, and I've even overclocked the gpu
and video memory and tested for artifacts. RAM is ok, too => the system is rock
stable.
