After searching on the web, I've found the information that this may have been caused by compiz deactivating plugins. So I suspect that it has deactivated: 'desktop wall' and 'grid'.
I've enabled them back and this seams to restore functionality. Can someone confirms me the cause andd the solution? If the cause was this, how can I find the issue that led compiz to do this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786922 Title: Unity keyboard shortcuts stopped working after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1786922/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
