Title:
  Using "Software and Updates -> Additional Drivers" to Switch Fails

Status in nvidia-graphics-drivers-390 package in Ubuntu:
  Triaged
Status in software-properties package in Ubuntu:
  Triaged

Bug description:
  When you are in the initial install state, you can easily switch from
  the Nouvea drivers to the Nvidia drivers by choosing the option in
  "Software and Updates -> Additional Drivers".  However, when you
  attempt to switch back (by selecting the nouveau option and clicking
  Apply), and subsequently reboot, your system will still come up using
  the Nvidia drivers, and you will WTF.

  And then, if you visit Additional Drivers, you will be presented with
  grayed out options for both nvidia and nouvea, and the only selectable
  option will be "continue using manually installed driver".

  The reason for this is that the tool, when reselecting nvidia in the
  GUI, uninstalls the nvidia-drivers-390 package, but because it's a
  metapackage (or at least I presume this is the reason), it doesn't
  uninstall its dependencies, which causes the Additional Drivers tool
  to believe it's in a non-automanaged state, and the nvidia drivers
  never actually get uninstalled.

  You can fix it by doing an apt autoremove and rerunning the Additional
  Drivers tool.  But obviously there is no real way for inexperienced
  users to know this.
