Lately I had a bad time trying to switching back from nvidia drivers to video-linux using mhwd
.
$ 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 /etc/modprobe.d/mhwd-gpu.conf
.
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.
