For some reason, sometimes when I boot up I can't reach the login screen. Instead it goes to a blank screen with just a mouse cursor. I've tried rcxdm stop and restart as well as sddm restart. After trying to restart the PC a few times, it would "magically" reach the login screen. Also I am using nvidia drivers if that makes a difference. This only started after my comptuer crashed. Attached is the .xsession-errors-:0
