Public bug reported: When switching windows using the alt-tab method at the desktop (unity), x-server crashes - screen goes black with only an underscore at the top left (not flashing) - keyboard does not respond - reboot is the only way to recover.
Several apps were open and x-session-error was no help determining which is the problem.
