I'm on Ubuntu 12.10. I installed the xubuntu-desktop package to see if I would like it and determined I would prefer to keep using unity. Ever since I did that I've been running into certain issues when using unity. I never had a screensaver before, but now there is one and I can't seem to turn it off or configure it from the settings menu.
Coming back from the screen saver also results in a compiz error message sometimes. I also have a new update notification icon as mentioned in this related question.
How do I turn off the screensaver? I'd like to remove the package completely if I could.
