(solved) Can you start kwin on NixOS without the drm component?
It appears the H11DSi mainboard from super micro doesn't have resizable BAR support and therefore the xe and xedrmfb driver get unhappy.

When I "systemctl stop display-manager.service" I get the blinking curser in the top right. But as soon as it starts the monitor looses signal and the logs show:
The answer is:

However I'm currently on the latest bios version which has additional signature checks in place and doesn't allow to downgrade (that easily) anymore...
If you have the tools:- I would take the chip off the board and do a full read and verify of it. Erase the chip, flash the new file and verify Then put the chip back on If it boots \ 🙂 / if not 😢 . If you don’t have the tools:- HP did have a BIOS recovery method around the time this system was released. It involved putting the latest BIOS from HP on a USB stick with a default name (model neame I think). Putting the stick into a USB2 port (NOT a USB3). Turning it on a...
