Today I upgraded to Ubuntu 15.10, no errors happened during the upgrade but after the upgrade I can log in using my username and password but unity does not work. No launcher, no panel absolutely nothing just the background.
I tried to start unity myself using
compiz --replace unity it gives me an error about a missing function definition in
libunity.so and it fails to load.
Please can you help me with this?
sudo apt-cache policy libunity9 is
libunity9: Installed: 7.1.4+15.10.20151002-0ubuntu1 Candidate: 7.1.4+15.10.20151002-0ubuntu1 Version table: *** 7.1.4+15.10.20151002-0ubuntu1 0 500 http://sy.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages 100 /var/lib/dpkg/status
After trying to follow the two answers the error message has changed as follows
DISPLAY=:0 compiz --replace unity outputs to standard error
