I installed Steam a few weeks ago, and it kept bothering me to add the ppa
ubuntu-x-swat/x-updates,so I did it yesterday. After I installed it, my computer was fine until I rebooted. The computer wouldn't boot, it just froze on the splash screen of Elementary OS.
In the recovery mode, I did '
ppa-purge ubuntu-x-swat/x-updates', and then booted from the recovery mode, and it went fine.
But now I can only boot from recovery mode, else it will just freeze on the splash screen, the problem is that after I boot, my cursor disappears when not moving, and flickers while moving.
How can I fix that? Do I have to reinstall the system?
I just noticed that Gala(elementary OS's window manager) is constantly at 200%+ CPU usage, and there are other instances of it with 20~40% of usage.Not shure if it is related.
