# Why can't the desktop remember that I don't want mirrored displays when I connect my laptop to the docking station?
* this bug actually can't be reproduced every time I plug in an external monitor. It's hard to tell if there's an underlying logic.
- # oneiric regression: When I connect a monitor to the DisplayPort output, sometimes the sound output also switches to it (but sometimes it doesn't, I couldn't figure out why). The sound output setting is buried deep into Control Panel / Sound Settings / Hardware / Profile, so it took me a while to figure out what had happened the first time.

- # oneiric regression: (related, but distinct from previous bug) sometimes when I switch on the DisplayPort output I get no sound output at all, no matter how I set the Profile in Sound Settings. The only way to make sound work again is power cycling the external monitor.

- # long-time issue, confirmed on precise: When the video mode changes, full-screen windows often get shuffled on different workspaces and don't come back to their original locations when the resolution changes back. This is particularly annoying when plugging/unplugging monitors.

# the "Desktop Cube" plugin of Compiz makes the display flicker briefly every time I switch workspace. This happens both with a Thinkpad X201 (Arrandale) and X200s (GM45).

# --There's a dead "Workspace Switcher" icon on the dock that doesn't do anything when I click on it and I cannot even remove it from the dock--
* It turns out that this icon works only if you enable Expo in compiz. Ok, but why can't I get rid of it??
