I have a very odd problem with Ubuntu 11.10. Here is a picture of it:
The window in the picture is maximized, but for some odd reason it does not cover the entire desktop area. That area of the desktop the window does not cover is a dead area - I also can't drag desktop items to there, though I can drag not-maximized windows to that area.
Rebooting doesn't help. The problem started after I configured some windows partitions to automount on startup(though I don't see how that could cause the problem...)
Does anyone know a way to fix this?
