I'm currently trying to get a HD 4670 aka RV730 XT to work against
X.org
1.16, xf86-video-ati 7.4.0 on a Linux 3.16.1.
Can anyone tell me: Should this card be able to handle an average
Gnome
desktop?
Of course.
The problem was: 3D rendering did not work at all.
Starting gdm lead to hanging Xorg. Calling glxgears on a twm session just rendered a black window, which stayed even if the process was killed by CTRL+C. I managed to get glxgears do do its job by setting "vblank_mode=0".
I guessed my card does not like to play along with vsync at all. So
I
went ahead to disable vsyncing (tearing is still better than no
display
at all). Setting it globally in /etc/drirc seems to get glxgears
running.
Testing Xonotic on twm showed, that the card was now able to handle
3D.
But: gdm still was extremely sluggish and eventually froze. Starting gnome-shell directly from startx gets me to the desktop, but any
action
freezes the process.
Is there still hope for this card or should I get rid of it?
It sounds like there's a problem with interrupt processing on your
system. Please provide the dmesg output. You might try disabling/enabling MSI to see if that works around the problem.
Thank you so much for this hint! Booting using radeon.msi=0 finally brings the system into a usable state. The dmesg of a default boot (i.e. radeon.msi=-1) is available at http://pastebin.com/gS1xHYPc
Can you file a bug report at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI component "DRM/Radeon" and attach the dmesg output there?
Also mention what chipset your system uses and whether the card is AGP or not.
