Graphic desktop unlock glitch

Hi all

recently (maybe past 2-3 weeks) whenever I come back to my locked PC after a brief absence I find the password box does not initially display on the lock screen - the mouse cursor happily swims around

I previously learned the TTY Console trick and use Ctrl+Alt+F2 then switch instantly back to desktop with Ctrl+Alt+F1 and then it does display the login password, and I unlock and everything works.

On rare occasions I find the PC seems to have rebooted and all my opened apps were closed

Any suggestions/explanations most appreciated

  1. Have you tried just typing the password? :innocent:

  2. When that happens, please post the relevant part of the output of:

    journalctl --boot=-1 | tail --lines=100

    (Meaning: give the log of the previous boot and only the last 100 lines)
