Hi Jonathan, Thanks for the additional info. So it seems something does not liking your 3 monitor setup. I noticed you are using the open source radeon driver. Have you tried the fglrx binary driver? Perhaps there is better multi monitor support in that driver.
I'm going to modify the bug headline and description to better describe that this issue is caused by having three monitors connected. I'll also look through more of the attached log files. Please let me know the results when using the fglrx driver. Thanks, Chris ** Summary changed: - unity launcher and window borders missing upon login + Unity Launcher and window borders missing upon login when using 3 monitors ** Description changed: In the past 36 hours an update released broke something. Now I only have the desktop background and icons shown, but no unity launcher or window borders. This is on a 2 GPU system with 3 displays on one card. I noticed in the apport some xserver errors, but don't know if they are relevant to the issue. To reproduce: - All that is needed to produce this result is to log into the machine. + All that is needed to produce this result is to log into the machine with three monitors connected. Note that when two monitors is used, it works correctly.
