Public bug reported:
Binary package hint: gnome-control-center
This happens on Lucid 10.4.02 with gnome-control-center version
1:2.30.1-0ubuntu1
I am not sure this is specifically gnome-control-center, but I figured
I'd start with that package and we can move as appropriate.
There appears to be two bugs here, but I wanted to keep the initial
report as one issue, in case they're actually related. For what it's
worth, I have reproduced this issue on a Lenovo X200 and have users
internally who can reproduce this issue on a Lenovo X201 and a T410 on
several different types and sizes of external monitor (all attached via
display port -> DVI converters).
The two issues are:
- Windows "get lost" when display properties change.
- The display property preferences aren't saved when undocking / re-docking.
Here's how to reproduce:
- Install Lucid Laptop on an X200
- Attach the laptop to a docking station connected by display port -> dvr to a
24" monitor
- Configure (system -> preferences -> monitor) displays to not be mirrored,
show monitors in panel checked, drag the monitor to a different orientation,
and increase the resolution in the monitor to something other than what the
laptop has.
- Open a web browser, put it in the 24" display.
- Open a terminal and a gnome app (I used gnome mine) in the laptop display.
- Detach the laptop (without suspending) to simulate going to a meeting, etc.
At this point the first bug (about windows getting messed up) occurs.
Notice that, while the browser window is moved to the laptop display,
the gnome mines and original terminal disappeared. If I open a new
terminal and run ps, I can see they're still running, but they're not on
any of my visible/accessible displays.
- Re-attach the laptop to the docking station
At this point, the second bug is reproduced. The monitor configuration
has reverted to "mirrored displays." When I reset my preferences to what
I want, the original browser window (as well as the preferences window)
moves to the 24" monitor, but my gnome mines are still missing, as well
as the original terminal (the new terminal I opened in the laptop while
detached in order to check for the disappeared window's pids is moved to
the new monitor).
