On a Dell Latitude E6500 with Mobile 4 Series Intel Gfx i get with karmic after logout
from a 'failsafe session' or 'KDE' session,  a black screen.   Alt-Ctrl-F 1, 2, etc show
no effect, i.e.  screen stays completly black,  No virutal console prompts.

Looking at the Xorg.0.log shows that the driver crashed on shutdown:
