I'm also getting this crash with the latest unity and all updates as of 2012-06-11.
I can force this crash by opening nautilus and pressing Control-N 20 times to open 20 nautilus windows. The next time I press Alt-Tab or Super-W I will get the crash. By opening 20 nautilus windows I can also crash Gnome-Shell, so I think this is definitly a graphics driver issue :-(. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/977804 Title: Unity crashes when many windows are opened (intel_do_flush_locked failed: No space left on device) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/977804/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
