xfree86 hangs on CTRL+ALT+BACKSPACE
I have a big problem... I quit X alot since I multiboot for various reasons, and xfree have a tendancy to hang right as the screen has turned black after hitting CTRL+ALT+BACKSPACE. This means I have to hit the reset button on the box, and I really dislike to do this. In part because I have some very big harddrives and forcechecking them with fsck ever 5 or so days when I reboot, just doesnt cut it, and also because its generally no good for hardware - and corrupting my filesystem is the LAST thing I would wanna do...
So, does anyone know why this happens? Note that it doesnt happen every time, but its definetely a high ratio... Could it perhaps be Nvidia?
