black screen after cold boot Debian 13 AMD GPU Plasma

Help

Hey Team,

I get a black screen after cold boot, if I restart my machine, it works normally.

I tried some of the workarounds already:

I tried different themes, I tried X11 and Wayland.

I tried to look up the race condition, but from the SDDM logs it seems that AMD drm finishes before SDDM starts.

I could also open the login screen with a theme I picked:
/usr/bin/sddm-greeter-qt6 --test-mode --theme /usr/share/sddm/themes/Utterly-Nord

There are no error messages here either.

Specs:

Debian 13 - 6.12.73+deb13-amd64
MSI B650 GAMING PLUS WIFI
Radeon RX 7800 XT

Let me know if you need more details!

Thank you in advance for taking a look!

I think you’re going to have to give us the output of journalctl -b -1 --no-pager for us to work this one out.

Hey!

Sure, no problem.

I can see this there:

I ran this to sanitize:


sudo journalctl -b -1 --no-pager | sed -E 
-e “s/$(whoami)//g” 
-e “s/$(hostname)//g” 
-e “s/[0-9]{1,3}(.[0-9]{1,3}){3}//g” 
-e “s/([0-9a-fA-F]{2}:){5}[0-9a-fA-F]{2}//g” 
-e “s/[0-9a-f]{32}/<MACHINE_ID>/g” > cleaned_journal.txt
```

I am just a new fellow here, how can I upload the file?
Do I need to pick a trusted hosting solution and share a link?

You should be able to paste it directly into a message. I like to setup the code block formatting before pasting. Put 3 backticks on a line, leave one line blank, then put 3 backticks on the next line. Paste your code on the blank line in between the backtick blocks.

Hey,

Got to the limit.
