After upgrading from 17.10 to 18.04, my system became sluggish after restart.
I have auto login enabled, so that still works, yet any action afterwards was very slow. During boot, error reporting ran and asked me to send the error report, yet on sending I started to type in my password yet the window would freeze so I was unable to do anything further. I could only reboot (Magic REISUB)
(This will happen for any application with stored passwords, e.g. Chrome).
How can I resolve this?
