Driver Manager is Frozen

[cstoudt]

Cinnamon --version 3.8.9
 Linux Mint 19, 64 bit
Graphics Card: NVIDIA GK107 [GeForce GT 740]

Issue
After a fresh install, I opened Driver Manager and it reported that the video driver "xserver-xorg-video-nouveau (open-source)" was in use. It also reported that "nvidia-driver-390 (recommended)" was available.

I selected "nvidia-driver-390" and hit "Apply Changes." The driver installation appeared to complete and I was prompted to reboot the system.

After reboot, I noticed that the video card fan is stuck on high-speed.

I went back to Driver Manager. It reported "No proprietary drivers in use." The controls and driver selections are grayed-out and changes cannot be made.

Other information
Uninstalling and then reinstalling Driver Manager did not solve the problem.

@cstoudt Is Driver Manager still frozen or were you ever able to resolve the issue?

[cstoudt]

@icarter09 I had to purge and then reinstall the nvidia driver with apt. After reboot, the nvidia driver operates properly. Driver Manager displays nvidia-driver-390 as currently in use. However, if I try to switch to the xorg driver and then back to nvidia then Driver Manager freezes as I described.

@cstoudt hmm. Wondering if the xorg driver is the cause of the problem.

[cstoudt]

@icarter09 The xorg driver runs fine. The problem occurs when I use Driver Manager to switch drivers.
My guess is that an error occurs when Driver Manager loads the nvidia driver and Driver Manager isn't catching the error. For now, I'm installing and loading drivers manually.

@cstoudt glad the xorg driver works correctly. Sucks that you have to load them manually. Did this issue start occurring after you upgraded to Linux Mint 19?

This isn't a Cinnamon issue so moving to mintdrivers.
