Hi thanks for the hint and the quick reply - i will try the rescan.If nothing else works, I read in some threads that unplugging the GPU and doing a rescan of PCI devices works for several people.
Personally with a RX570 (used for Proxmox boot and console before starting the VM), I don't usevideo=...
parameters and letamdgpu
load for that GPU to fix this for me (with the help of vendor-reset).
Being able to have a working console instead of using the video parameters sounds amazing, unfortunately i am on an nvidia gpu and threadripper cpu (so no iGPU console either) and can't justify upgrading yet so no AMD for a couple more years... Do you know of a similar solution for nvidia?
