I’ve been having exactly the same problem. I’ve just been reading this thread, as I have nothing new to add. However, you needed to know it isn’t just him.

I can usually get it to login after reboot and one failed attempt. It doesn’t matter if I reboot after the last session or when.

If you read the bug report, this is breeze SDDM theme related bug, the netrunner SDDM theme is based on breeze.
Switching to a SDDM theme that came with SDDM does not have this issue (maui, circles, elarun, etc.).

Thank you for this update. I changed the SDDM theme to default and the problem is now solved.
This way I cured the problem in three different machines running netrunner rolling.

Your welcome. Also, once this is fixed in the upstream breeze SDDM theme, I’ll back port the changes to our Netrunner SDDM theme.

Update: It turns out the issue is actually in the driver stack.
The latest workaround is force the use of DRI 3 in the /etc/X11/mhwd.d/intel.conf file.

Edit this line:

Option  "DRI"    "True"

to:

Option      "DRI"    "3"

Yeah, that seems to have fixed it. Thanks!

No problem.
Hopefully, this gets fixed upstream soon.
