I tried to reinstall drivers and now I'm getting another error (see attachment), in particolar it seems there is some compatibility issue with the last version of kernel:
ERROR (dkms apport): kernel package linux-headers-5.7.10-050710-generic is not supported Error! Bad return status for module build on kernel: 5.7.10-050710-generic (x86_64) thanks for the hints on the new GPUs to consider, I'll check to see if they're in line with my budget; I also have to check if they're compatible with my P5QL Pro Motherboard.
