I'm having problems with the intel drivers and OpenGL. With OpenGL sceensavers, I don't really know how to describe it but I can guess what's on the screen but it's garbled. With some OpenGL games, I get a black screen. I get the following message on the terminal: get fences failed: -1 param: 6, val: 0
I also get that message when running glxgears which works fine. My video card: 00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) 00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
Intel has no special interest in the 8xx drivers anymore, so I assume this is broken and will stay broken for a while. Can you try replacing /usr/lib/xorg/modules/dri/i810_dri.so with the version from intel-dri in extra and test again? I might want to revert just the i810 driver for this. The get fences warning is the same I get. This is because the kernel DRM drivers for intel don't have all the features the mesa DRI driver has. I hope this will get fixed with 2.6.29, but I'm not sure about that. The warning is harmless, but I can imagine people will file bugs for it the same way they did for the "Failed to initialize TTM, falling back to classic" messages.
