The only “solution” i found was goung back to kubuntu 22.04. Since then it works without Problems. I hope somebody finds the bug and fixes it sometime 🙈 I didn’t seem to have problems with ubuntu 24.04. But i didn’t try it very long maby i just didn’t encounter them.

Thanks Kubuntu22 works :)

No I’m not sure what the default is I will compare it

Thanks I will look into it

It shows the Framework logo for a couple of seconds (but no ubuntu or kubuntu logo), and then the screen just goes black, no cursor, nothing. But the powerbutton glows. If I press esc, nothing happens (Normally, I think it shows the output of the boot process)

I’m not sure what you mean with f12, and I haven’t tried it, but I will probably tomorrow.
