So, I was running Ubuntu 14 LTS more or less happily (nvidia drivers were working fine with unity and all). Then the upgrade manager asked if I wanted to upgrade to 14.10. I did the upgrade and everything worked fine. Then it asked me if I wanted to upgrade to 15.04 vivid. Sure! What can possibly go wrong...
After the update I was stuck in a login loop. From vivid to livid. I resolved that by manually installing the latest nvidia drivers. Now I can login and run programs but Unity is just not working.
If I try to run unity from the terminal, I get two suspicious error messages:
something about Upstart
stop: Name "com.ubuntu.Upstart" does not exist compiz (core) - Info: Loading plugin: core compiz (core) - Info: Starting plugin: core start: Name "com.ubuntu.Upstart" does not exist
something about OpenGL
compiz (core) - Error: Plugin 'opengl' not loaded.
I tried:
- reinstalling the nvidia drivers via purging
- resetting the compiz profile
- reinstalling via purging ubuntu-desktop/compiz/unity
- booting with Upstart: it replaces the Upstart error with "service unity-panel-bla unknown" or something like that. The openGL error is still there.
Now this is getting very annoying. I would just like to let unity know that it can use openGL just fine and get on with my life. Any advice on how to solve this problem?
