I updated my opensuse from 42.1 to 42.2 following the guide from https://en.opensuse.org/SDB:System_upgrade but after a few days, my screen started to freeze, the mouse and changing to terminal 1 (ctrl + alt + f1) still working.
Output from command “egrep -i ‘error|fail’ ~/.xsession-errors”:
kdeinit5: Communication error with launcher. Exiting!
kdeinit5_wrapper: Warning: connect(/run/user/1001/kdeinit5__1) failed: : Connection refused
