No video after installing GPU driver

I am absolutely new to proxmox (and linux as well)

I have an AMD R5 270X GPU installed, and assigned to a vm. The passthrough is working fine (used parsec to access the vm after adding the gpu). After started installing the AMD graphics driver, the vm frozen, and could no longer access it.

Also tried adding video=efifb:off as it was mentioned here, but it didn't help.

I am using the most recent proxmox version with only windows 10 vms installed on an M.2 drive
 
can you post the output of 'dmesg' and the vm config (qm config ID)?

if you boot the vm again (e.g. without the passthrough) is there anything interesting in the windows event viewer?

ok, the dmesg and config look normal/ok so far, but i noticed from the dmesg that the radeon driver gets loaded on boot. could you try blacklisting that driver in pve so it does not get loaded?

what about the windows event viewer entries?
if you boot the vm again (e.g. without the passthrough) is there anything interesting in the windows event viewer?
