Bug Description

I am having issues with the new Ubuntu 13.04 upgrade. I upgraded this weekend at home and had no issues, but when I got to work this morning and tried to setup my laptop with an external monitor, like I have used with Ubuntu 12.10, the both screens are displayed; however, the Launcher sidebar is missing on both monitors and I have no choice but to shutdown the laptop and use only the laptop display. This is an obvious bug in 13.04. Is there a fix yet, and if not, is there at least people working on this issue? Below are my specs resulting from "sudo lshw -C display; lsb_release -a; uname -a". Thanks in advance!

The Package, icc-profiles-displays, is a wild guess. Being nobody was kicking back any activity on the Bug, I thought I'd assign it to a some group, right or wrong. At that point maybe they'll know which Package it rightfully belongs to. You can only hope.

Hello guys,
I Have the same problem.
Every time i plug in a external monitor, the launcher, the menues and the windows frames are missing.
To work normally after that, I have to restart my computer.

I think this error is a compiz problem, because every time when this happend a error is shown, where the Executable Path links to compiz.

I think the problem could be the graphic card: I have a HP Probook 4720s. When I run lspci, the following line shows my grapic card:

`01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV710/M92 [Mobility Radeon HD 4350/4550]`

If you need more information, tell me how to gather it and i will post it.
