If the powesaving comes in, for example standby, when resuming I’m left with the topbar and the volume controls but no login box to input password and no way to resume system activity, only way is hitting ctrl alt f1 and do a reboot.
Now I know there is a similar problem on KDE and if I remember correctly there is a patch already but my problem is on Gnome.
I have collected some log files if they are useful in diagnosing the issue.
In KDE you have options to configure screenlocker to somewhat prevent this but I can find such config tool in GNOME.
