Problems With Driver Manager?

[PhysicistSarah]

When I go to the driver manager and select a Nvidia driver to use, I get a prompt and enter my password and the driver installs.

But when I go back to the driver manager a minute later, it says that I'm using the default driver again.

What driver am I even using and is there any way to fix this?

ubuntu-drivers devices

on the command line will show what you have. Check its -h option for other options.

This allows me to see the list of available drivers, but doesn't show me which one I am using or how to change to a certain driver.

It lists the recommended driver(s), and then using the "autoinstall" option it will install the required driver.

john@john-Desktop:~/Documents/Memos$ ubuntu-drivers -h
usage: ubuntu-drivers [-h] [--package-list PATH] <command>

List/install driver packages for Ubuntu.

positional arguments:
 <command>            See below

optional arguments:
 -h, --help           show this help message and exit
 --package-list PATH  Create file with list of installed packages (in
                      autoinstall mode)

Available commands:
  list: Show all driver packages which apply to the current system.
  devices: Show all devices which need drivers, and which packages apply to them.
  autoinstall: Install drivers that are appropriate for automatic installation.
  debug: Print all available information and debug data about drivers.

Then you can look in Kinfocenter, under the Graphical Information dropdown and see the actual version installed.

My driver is detected ok, but the manger just relies on what 'ubuntu drivers' scripts return to it.

So it may be a bug in that.
