Lately I had a bad time trying to switching back from nvidia drivers to video-linux using
$ sudo mhwd -r pci video-nvidia-470xx $ sudo mhwd -a pci free 0300
This prevented starting X.
After some sweaty moments, I discovered that one of the reasons was the presence of
blacklist nouveau in
I was wandering if it could make sense that
mhwd would check that file and possibly emit a warning if the module that is being installed is blacklisted.
