This seems like a graphics issue. Please confirm if the problem still exists with LATEST vanilla kernel. If yes, please boot with kernel parameter "nomodeset" and see if the problem is still there. thanks, rui On Mon, 2023-01-30 at 06:52 +0000, Topi Mäenpää wrote: > Hi, > > I hope I'm not breaking rules by posting this question here.
