I got this bug when trying to install Ubuntu on my Macbook Air 4,2 using the instructions from here: https://help.ubuntu.com/community/MacBookAir4-2
After using the fix-i915.sh script, I rebooted. The login screen appeared normally at full resolution. After I logged in only the desktop background and mouse appeared (mouse was movable with the trackpad). Then, after about 60 seconds, I got an error report that Compiz crashed (submitted Bug #870092). Then about 5 seconds later, I got an error report that 2d-Unity had crashed (which sent me here after I clicked submit report). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/850893 Title: unity-2d-launcher crashed with SIGSEGV in geis_finish() To manage notifications about this bug go to: https://bugs.launchpad.net/unity-2d/+bug/850893/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
