[toad]

Public bug reported:

Binary package hint: linux-image

2.6.32.19 messed my Display, once a day, sorry no further Information.
Switching to console is not possible, numlock also does not respond.

Also switching to another user via the panel and back does not work, after
the second user logs out, the screen shows a blank screen with a mouse cursor.

With 2.6.32.18 everything seems to be ok.
