I tried this but didn't work for me. But it could be because I didn't use the right patch.diff file. My patch.diff starts at: "--- a/src/gallium/drivers/i915/i915_screen.c" and ends at "switch (param)" from the patch link provided. After that, I just tried building " libgl1-mesa-dri" with: sudo apt-build install libgl1-mesa-dri This took a long time to complete, but doesn't fix the issue. I guess I will wait for the patch to be pushed into Ubuntu updates eventually. Any idea when that would be? Note: I can do "startx" from command line. However, the graphics login doesn't appear at startup because of segfault in gnome-session-check-accelerated-gl-helper. Thanks,Santosh
