I am using Linux Mint 20.1 on a Thinkpad T14(AMD). Every time I close the lid or let the laptop go into suspension mode due to idleness, the screen turns black and the computer doesn't react anymore until I shut it down.
My software manager showed me supported possible Kernel updates until 5.13.40. I tried updating to unsupported Kernel versions 5.15.x anthed the issue seems to dissapear, however then I get Wifi problems so I rolled back to the 5.13.30 Linux Kernel.
Does anybody have an idea how I could fix this issue? Thanks in advance!
