Display not found/no graphical mode at startup since kernel 6.1.7 in Tumbleweed

English Install/Boot/Login
#1

Hi! I’ve had the problem since a few kernel versions that the system doesn’t make it to graphical mode anymore. Instead, it still displays the console login.
The last working version is 6.1.6.
Unfortunately I can’t find the cause. At first I thought it was the amdgpu driver, because now the error message “amdgpu: SECUREDISPLAY: query securedisplay TA failed.” is displayed. But in the dmesg of the 6.1.6 this is also produced, but just not visibly output. Are the dmesg outputs useful?
Does anyone have any ideas what else I could check?

dmesg of failed booting: [ 0.000000] Linux version 6.1.12-1-default (geeko@buildhost) (gcc (SUSE Linux - Pastebin.com
dmesg of successful booting: [ 0.000000] Linux version 6.1.6-1-default (geeko@buildhost) (gcc (SUSE Linux) - Pastebin.com

Kind regards, Sven

Graphical mode is implemented by user space, not kernel. Provide full output of journalctl -b --no-pager after boot in each case. And please, upload them to https://susepaste.org, not to advertising site.

X server not starting anymore
#3

Thank you for your help. I was able to find out that ssdm could not start because the X server in turn could not start. I then found out that either dkms or the displaylink driver as of 6.1.7 is preventing the X server from starting. Uninstalled it and now it runs. So now I know where to look further.
