Computer hangs using NVIDIA driver after bad uninstall/install, 940MX

For a period, I had the graphics-drivers PPA added, with the 415 driver installed. I wanted to go back to the proprietary driver I had before, the 390 driver, but I made a mistake in removing the PPA before switching back. During the switching process, Ubuntu gave an error message (unfortunately I don’t recall the error message, but it said something about cache).

After restarting my ststem, the boot process would be stuck on a flood of “Starting NVIDIA persistence daemon” and “Stopping NVIDIA persistence daemon” messages, and to get a successful boot I needed to enter recovery mode and prime-select intel.

If I enter nvidia-settings into the terminal whilst using nvidia-driver-390, the system hangs. It also hangs if I run, with the .log.gz generated only containing the following:

Any help in resolving this would be greatly appreciated.

  1. Force uninstall everything nvidia related.
  2. Reinstall mesa* and xorg* packages.
  3. Install the desired driver release.

Ubuntu forums might help you better since your issue is not related to NVIDIA drivers per se.
