The GPU is locked up and the only way out is the power button as far as I can tell. The info from Laura's response (https://bugs.launchpad.net/ubuntu/lucid/+source/xserver-xorg-video-intel/+bug/554835) is pointing in a productive direction. It's a kernel bug that can be worked around by setting a boot-time flag. It affect the Intel 855 graphics chipset (which hardly anyone uses :-). As best I understand it: - The Kernel mode-setting for that driver has stability problems, so they disabled it by default in the kernel released with Lucid. - Starting up a system with kernel mode-setting disabled (at least if it needs to prompt for encrypted filesystem passphrases, or maybe always) leads to GPU lockup when the X server starts which leads to a conundrum - enabling kernel mode-setting is bad, and disabling kernel mode-setting is bad. But I daresay that disabling it is badder, and the workaround for now is to burn a change into initramfs that enables kernel-mode setting.
