Public bug reported:
Binary package hint: xorg
I use a laptop as my primary machine. About 70% of the time it's
connected to an external monitor. The rest of the time I use it on its
own.
I've always had problems switching between the two. Prior to the Natty
upgrade, if I switched from the monitor to the laptop and then unplugged
the machine, the display would turn off and I couldn't get it back
without doing a hard reset.
Since the Natty upgrade, the problems have gotten worse. The
plugging/unplugging issue persists (though sometimes I can get the
screen back by unplugging/replugging a second time).
But another problem has cropped up. Since upgrading to Natty, when
switching between displays, the screen will just freeze. I can still see
everything, sometimes even move my mouse around, but the system doesn't
respond to any clicking or keyboard strokes. My only option is to power
down the machine and restart it.
This happens when switching—I turn one display off and the other one on.
I can sometimes avoid this issue by turning on both displays at the same
resolution first, applying the changes, and then going back and turning
off the second one. But that's not failproof either.
