Public bug reported:
Since upgrading to linux-generic-pae 3.0.0-15, the computer always
freezes during boot. When it freezes, the screen turns 2/3 black, with
consistent, odd many-colored vertical bars on the rightmost 1/3 of the
screen. This does not happen with previous versions of linux-generic-
pae (up to 3.0.0-14). Additionally, selecting recovery mode from grub2,
then selecting resume boot results in a normal boot. However, if I do
this, the computer fails to wake up from sleep, resulting in a black
screen.
