I have a lenovo laptop with an external dell screen, which used to work together.
After the last reinstall when I plug the screen it just restarts in a loop (the screen). I was able to disable it, so at least I can work (the main screen was resetting too) and now I can see, even when disabled, kscreen reports the screen added and removed every 1-2 seconds.
journalctl shows nothing, and the screen works fine with another laptop with LMDE.
Any advice would be appreciated.
