Hi list,
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?
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?
Best wishes,
Christoph
