Hi,

On my system (and seems that others are affected) switching from the X
server to any tty using Ctrl+Alt+Fx keys results in some kind of nice
paint artwork. The problem is that you cannot use any ttys since nothing
is written on the screen. However you can continue to type in commands,
and they're correctly taken into account.

I do not use any framebuffer parameters when booting, my boot string in grub is :
kernel          /boot/vmlinuz-2.6.31-13-generic root=UUID=53dfbfeb-5955-48e2-9039-e6c3b9b219d0 ro quiet splash

The issue appeared after kernel upgrade to 2.6.31-13-generic, it was
absent from 2.6.31-11-generic. The problem is that at the same time
there was an NVidia driver upgrade, to I don't know if this is kernel-
related or nvidia-driver related. However I think kernel is more likely
to be affected.

Seems that it does not affect all the users, especially the ones with Intel X drivers. Someone with en EeePC was not affected, see there in French :
http://forum.ubuntu-fr.org/viewtopic.php?id=317166&p=77

This bug is quite critical I think, since it's critical to get vts
sometimes to get out some blocking situations.

Rgds,

gojul
