for more info.
To reproduce: randomly, after a number of times (I would guess once
every 10 or so times), typing in my password after the screen is locked
via gnome-screensaver, the screen remains black/blank with just the
mouse cursor there. Ctl-Alt-F1 does not change this, neither does Ctl-
Alt-Backspace nor Ctl-Alt-Del. As mentioned in the above referenced
comment, the only workaround is to disable gnome-screensaver.
Note that I am not in a position to log into my system while this
happens and therefore cannot run any diagnostics or tests.
The system is a Acer Aspire AS5740-5512 laptop. When closing the laptop
lid when this happens, the screen becomes completely black -- the mouse
cursor is gone.
The only way to recover is to hard reboot the system (hold down the
power button).
