Edit: Kubuntu22.04 seems to work. Thanks for your help.

I’ve tried to install plasma onto my new Framework 16. When I installed kubuntu directly, then after the second reboot, my laptop didn’t start up again. It shows the Framework logo, but then nothing. Then I’ve tried to install Ubuntu first, and everything worked, but after installing KDE afterwards and rebooting, I’ve the same problem. Even esc doesn’t bring anything up. What am I doing wrong? Does anybody have experience?

I’ve used Ubuntu/Kubuntu 24.04
