[Bug 1761593] Re: Uninstall left nouveau blacklisted

[Kev Bowring]

Rechecked this (multiple times)

Using the GUI at Software & Updates>Additional Drivers appears to now
not remove conf files and hence user is left with 640x480px (assume
because of the blacklist file left in /etc/modprobe.d)

If one installs via apt and then purges - the nvidia conf file is
removed and a normal at reboot results.

The same behaviour is seen if installed via Software & Updates and then
removed with apt purge.

Pretty positive this was not previously the case when using the GUI to
install nvidia driver.

Only have 1 card to test against - so possibly only affects nvidia-340.

Notes from testing and some pastebin of terminal logs attached.

Title:
  Uninstall left nouveau blacklisted

Status in software-properties package in Ubuntu:
  Confirmed

Bug description:
  Following a successful install and subsequent use of nvidia-340 -
  uninstallation of nvidia via Additional Drivers led to a reboot to a
  desktop at 640x480 px.

  Investigation found an nvidia created file left on the system
  blacklisting nouveau, deleted file and rebooted to normal desktop.

  Didn't think about ubuntu-reporting this - can try and replicate and
  apport-collect if it's of any use.
