Steps to reproduce: 1. Start X 2. Run compiz 3. Switch to VT1 via ctrl-alt-f1 4. Switch back to X via ctrl-alt-f7 The result is that X will remain displaying a black screen from then on (the mouse cursor is visible and still moves). Switching to a VT after this locks up the keyboard. When compiz is not running this bug does not occur. I am not using kernel mode setting and booting with nomodesetting made no difference. This problem was not present in 2.6.28. The problem is reproducible every time. Graphics card is an i915 in an EeePC 900: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 04) This might be http://bugzilla.kernel.org/show_bug.cgi?id=12264 but I can't reopen that bug and this bug might turn out to be different. Might also be related to http://marc.info/?l=linux-kernel&m=123499984611624&w=2 . -- Sitsofe | http://sucs.org/~sits/
