It's funny, but the back-and-again workaround does not work for me (ctrl-alt-f1, ctrl-alt-f7) I just get back to black.
My only options are reboot, ctrl-alt-backspace, or "for file in `ps ax | cut -f 1 -d ' '`; do kill $file; done" from another console. -- Garbled screen during install https://launchpad.net/bugs/74875 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
