Public bug reported:
Binary package hint: gnome-control-center
Opening the display preferences for the first time after the computer is
restarted causes the system to crash. By crash, I mean the screen turns
black, the cursor freezes (or disappears), and the system is
unresponsive to keyboard or mouse stimuli.
The purpose of opening the display preferences is to send the display to
an external display (monitor or projector) via the VGA port. The
external display is off when Ubuntu is started, then powered on, then
display preferences is opened, resulting in a crash.
Interestingly, if the system is restarted (via Restart..., or after Shut
Down...) with the external display connected (VGA) _and_ external
display powered on when Ubuntu starts up, display preferences opens
without a hitch, detects the external display, and generally plays nice
with others. It is only when Ubuntu is already running, then the
external display is subsequently powered on, does this crash occur.
Additional details (enumerated per Launchpad's suggestion):
1) The release of Ubuntu you are using: Running Ubuntu 9.10 on a Dell Inspiron
E1505 laptop.
2) The version of the package you are using: The bug may be in
gnome-display-properties, but I cannot be positive. I believe this is part of
the gnome-control-center package, and I'm using version 1:2.28.1-0ubuntu1.
3) What you expected to happen: I expected the display preferences application
to open.
4) What happened instead: Fail.
Things I have not tried:
-External display connected via non-VGA port, such as a USB.
-Opening display preferences for the first time after a restart, without a
powered-on external display connected to the VGA port.
Thanks in advance to any who could provide information on a fix.
