Unity/Compiz crashes on each right click

[Guy Van Sanden]

Since the updates I applied on March 13, Unity and/or compiz crashes on each right click, be it on the panel, nautilus, the desktop or any application. After the crash, I can only log out or reboot to get a working desktop again.

Note that to make sure, I removed bumblebee and Nvidia, but same result

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Guy Van Sanden (gvs)]

Is there any easy way to revert the packages?

[Jelle Foks (jellefoks)]

I had this too, and have found out that it goes away when I turn off the "Shift Switcher" in the ccsm (compizconfig-settings-manager), and it comes back when I turn it back on...

Note: When unity crashes, you can get your desktop back this way: login on the console (ctrl-alt-f1), then type 'unity --replace', then turn back to Xorg (alt-f7). Then you should have your desktop back, but usually with all windows piled on top of each other in the first workspace...

[Guy Van Sanden (gvs)]

@Jelle, disabling the shift switcher did the trick indeed!

[Ralf (ralf-kaestner)]

Disabling the shift switcher solved it for me as well. Thanks

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 954079, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

Yes disabling Shift Switcher will solve this bug, but you dont need disable plugin entirely, just need to disable all mouse shortcuts for this plugin (Terminate -> Disable, etc..)
