Comment 48 for bug 633406

I just did a build using Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04) (i915), with xorg-server-1.9.0, xf86-video-2.13.0, libdrm-2.4.22, mesa-7.9-rc2, qt-4.7.0, kde-4.5.1, and linux-2.6.35.7. This is decidedly way downhill (from xorg-server-1.8.2/Mesa-7.8.2) - desktop effects will not even activate anymore. I can force-activate them, but then video is so slow as to be entirely unusable. Perhaps related to a new error message in .xsession-errors:

i915_program_error: Exceeded max nr indirect texture lookups (8 out of 4)

This is the only error (Xorg.0.log looks good).

Summary of some build variations (all using qt-4.7.0, kde-4.5.1., and linux-2.6.35.7):

mesa-7.8.2, libdrm-2.4.21, xorg-server-1.8.2, xf86-video-2.12.0
  ----> works (with glxcmd.c patch submitted earlier)
