Black screen login

[Kobold]

@RatherFly

I can wait for the OS to be fixed through the next update, but everytime I come back to the computer after the screen goes blank, I cannot login because the graphical username system seems to NOT recognize my PW.

Its always worth to look first in the Announcement Topic at the second post (few days after release):

The way you describe your problem, it might be related to Energy savings.

System freeze on suspend

A feature in systemd 256 freezing a user session when suspending may freeze the system.

• [SOLVED] System freezes after sleep since update / Newbie Corner / Arch Linux Forums
• Systemd 256 may break sleep

The issue is most prominent with Nvidia systems but reports exist that it may affect other systems as well.

System freezes for 60 seconds and then wakes back up or hangs after waking up

Since systemd v256, systemd freezes user.slice before sleeping. This process can fail due to kernel bugs, particularly when KVM is in use.[13] [14]

Messages in the logs will contain Failed to freeze unit 'user.slice' before sleep. When such an issue occurs, trying to login (start another session) would fail with pam_systemd(process:session): Failed to create session: Job 9876 for unit 'session-6.scope' failed with 'frozen'.

To temporarily revert back to the old behavior, edit systemd-suspend.service, systemd-hibernate.service, systemd-hybrid-sleep.service, and systemd-suspend-then-hibernate.service with the following drop-in:

[Service]

Environment=“SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=false”

But @soundofthunder suggestion to add a swap, could already help here.

I cannot login because the graphical username system seems to NOT recognize my PW.

This graphical login system called SDDM and KDE has widespread problem right now. That required some work arounds at the moment, hopefully we see some fixes.

I am now having trouble booting and shutting down.

But If you face this issue, when your system isn’t in hibernating state, then it might be this here:

KDE Plasma hangs on Shutdown, Restart and Logout

With KDE Plasma 6.1, the session saving feature can make Plasma hang.
A workaround is to disable it in System settings > Session > Desktop Session, by choosing “Start with an empty session”.

Since you still a new Linux as you wrote above, i recommend that using Timeshift on a external harddrive (rsync) and activating Reisub, gives you also additional safetynet around Linux.
