X cannot be started by SDDM (at boot), works when restarted

Hi! I have an up to date tumbleweed and and strange sddm/X problem:

when booting i have in xorg log :

**c340sev:~ #** grep "EE.*sddm" /var/log/Xorg.0.log
   439.286] (EE) Failed to open authorization file "/run/sddm/{7b523bcc-feec-43c7-93ed-bdf81167014b}": No such file or directory

but sddm is started :

Nov 23 14:09:01 c340sev systemd[1]: Started Simple Desktop Display Manager.
Nov 23 14:09:01 c340sev sddm[919]: Initializing...
Nov 23 14:09:01 c340sev sddm[919]: Starting...
Nov 23 14:09:01 c340sev sddm[919]: Logind interface found

if i do systemctl restart sddm the x start, i have in the log the same :

  1173.798] (EE) Failed to open authorization file "/run/sddm/{475b077f-e30d-4094-a438-36de98176511}": No such file or directory

but!!

**c340sev:/var/log #** ls -l /run/sddm/
total 4
-rw------- 1 sddm sddm 52 Nov 23 14:28 {475b077f-e30d-4094-a438-36de98176511}

what can i do to make this work?
i should mention that plymouth is not installed and is disabled in dracut and not present in initramfs

Thank you!

Has openSUSE worked on this system before?

Which Graphics?

Maybe this help:

You forgot to mention what isn’t working.

Yes, I see those messages (but with different numbers each time). But everything is working as it should.

Related: If I use “ssh -X” to login with X-forwarding, I sometimes get a similar message about “.Xauthority” not existing. I think it is just a standard information report from the X-authentication software, reporting that the file does not exist but will be created.
