Just pitching in to report that Option "ExaNoComposite" "true"
definitely solved this problem for me (as a workaround). I usually had 2-3 daily spontaneous X crashes as described previously in this bug, they stopped immediately when I added this option and restarted X. What exactly does this option turn off? OpenGL still works nicely for me (I develop opengl apps), but I don't run 3d effects in the window manager. -- Frequent crashes on i915GM (Thinkpad X41) Error in I830WaitLpRing() https://bugs.launchpad.net/bugs/176377 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
