http://ubuntuforums.org – Hi! I've a problem in my Samsung notebook with Sandybridge i5 2410m and Intel HD3000 graphic card, on Ubuntu 12.04. Yesterday I installed an upgrade, with a a new xorg video intel driver. Now I can't use unity 3D but only unity 2D because I think mesa driver doesn't work properly. Seems to be an OpenGL problem cause I did this test: glxgears: libGL error: failed to load driver: i965 libGL error: Try again with LIBGL_DEBUG=verbose for more details. 3906 frames in 5.0 seconds = 781.087 FPS 3913 frames in 5.0 seconds = 782.531 FPS 3906 frames in 5.0 seconds = 781.103 FPS 3902 frames in 5.0 seco (Hardware)
