Dear Maintainer,
After installing the nvidia-driver package, on boot I get these messages:
[FAILED] Failed to start systemd.modules-load-service - Load Kernel Modules. (this line is repeated 3 times.)
[FAILED] Failed to start nvidia-persistenced.service - NVIDIA Persistance Daemon.
At this point I'm stuck on the text screen with logs, X doesn't come up.
I can Ctrl-Alt-Fn to get to another text terminal to investigate.
It appears that the NVIDIA kernel modules didn't actually get built. I recall from previous installs seeing DKMS build modules from source; I saw no such messages this time.
apt-purge nvidia-driver failed to restore graphics.
