I'm having problems with Xorg randomly crashing on Ubuntu 15.10. I checked
~/.xsession-errors and there's some stuff in there about upstart, so I'm trying to delete it from my system. I read that since Ubuntu 15.04 upstart has been replaced with systemd, so not sure why it's still there (upstart processes are running now). A while ago I accidentally deleted some upstart config files so perhaps that's why.
Anyway I ran
sudo apt-get remove upstart, and then it said:
The following packages will be REMOVED ubuntu-desktop unity unity-greeter upstart
So I didn't continue. Why is ubuntu trying to remove the desktop and unity as well when I just want to remove upstart?
