Hello Linux Geeksters. In this quick guide I will show you how to recover your system from Unity freezes. This solution is only temporary, we still have to wait for Canonical to fix this bug.
When your Unity panel freezes out of the blue, you can recover your system by reseting Compiz:
$ sudo apt-get install dconf-tools
$ dconf reset -f /org/compiz/
$ setsid unity
As you may know, Ubuntu 13.10 Saucy Salamander is only two weeks old and there are many bugs that have not been discovered and fixed yet.
