Title:
whole screen became blank white - no recovery possible - after
unplugging and replugging external monitor
Status in “xorg” package in Ubuntu:
Expired
Bug description:
I have a laptop with an external monitor connected. When the monitor
is connected, I only use the external monitor. Usually, when I unplug
the monitor, the screen switches automatically, i.e. the builtin
screen turns on; when I replug the external monitor, the builtin
screen turns off an the external monitor turns on.
A few minutes ago I unplugged the external monitor, and the builtin
screen became all white. I could see the mouse cursor on a white
background and nothing else. The mouse cursor moved smoothly, but I
could'nt do anything.
Keystrokes such as tab, atl+tab, ctrl+alt+T (to open a terminal),
Ctrl+Super+D, and the like, did absolutely nothing (or they do what
they are supposed to do but I couldn't see it because the screen
remained white.
Replugging the monitor didn't fix the issue. When I plugged the
monitor, the builtin screen would turn off, the external monitor would
turn on but I could only see a white rectangle (probably of the same
size as the laptop built in screen) on a black background, and the
mouse cursor.
Switching between virtual terminals (i.e. Ctrl+Alt+F1 and Ctrl+Alt+F7)
worked, but wouldn't fix the issue.
I had no other option than reboot (which I had to do from the F1
virtual terminal), obviously losing all my unsaved work because of
such a stupid bug, when probably all programs were running fine but
invisibly.
Please tell me what can be done to force a "wake up" of the screen as
a workaround so next time this happens at least I don't have to reboot
and lose all my data.
I think this is a REGRESSION, or at least I had never, ever seen this
before in years of using ubuntu.
