I have an M6600 which runs Kubuntu 20.04. I have problems with the screen sometimes. The laptop boots and I am able to log in. After some while I get a brownish display with vertical stripes. Sometimes it doesn’t show the login screen.
What always works is setting
nomodeset in grub. Does this mean my problem is software related? I want to check first before I buy a gpu (even the M6600 gpus are quite expensive right now).
Here is some more information about the M6600:
