I have debian-powerpc CarbonCopied and Reply-To set to the bugreport
to get more eyeballs on this issue.

$ glxgears
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
431 frames in 5.0 seconds = 86.200 FPS
400 frames in 5.0 seconds = 80.000 FPS
400 frames in 5.0 seconds = 80.000 FPS
400 frames in 5.0 seconds = 80.000 FPS
400 frames in 5.0 seconds = 80.000 FPS
320 frames in 5.0 seconds = 64.000 FPS

glxgears looks fine

I install tuxracer, startup showed a mallformed screen,
but didn't crash my X-server.

Next was crack-attack installed  (hey, I have now games on my computer)
as glxgears it looks fine  (due the none fullscreen mode?)

Here the output that is on the console

So all three print that DRI is missing,
so it shouldn't a problem for blender


What is next to prevent blender crashing X-servers?
