Comment 6 for bug 179444

I see this problem as well on a dell latitude X200.

I have an external monitor; however, as far as I can tell this system only allows mirroring of displays, and not a dual monitor/Xinerama setup.

As far as I can tell the crash happens when:
1. laptop is booted outside of media base.
2. laptop is connected to media base.
3. Fn+F8 is pressed to switch to the external monitor.
However, it doesn't seem to happen every time (possibly only the first time the above steps happen, possibly semi-randomly otherwise)

One other possibly related thing that also happens sometimes:
1. Laptop is booted outside of mediabase
2. Laptop is closed.
3. Laptop is connected to mediabase
4. Laptop is opened.
At this point, the built-in display is shifted down by approximately 24 pixels (estimate based on size of upper panel, with garbage graphics appearing at the top. The mouse can be moved outside the desktop area proper, into the garbage area. If I use ctrl+alt+F1 to move to the console and back to X, the display is shifted back to where it should be.

I'm not sure if these two problems are related; they may happen entirely independently.
