Uninstall left nouveau blacklisted

[Kev Bowring]

SRU Request:

[Impact]

The driver package won't remove the blacklist file from /etc (/etc/modprobe.d/nvidia-340.conf), preventing nouveau from being loaded.

[Test case]

1) Enable proposed, install the new nvidia-340

2) Uninstall nvidia-340

3) See if either /etc/modprobe.d/nvidia-340.conf or /lib/modprobe.d/nvidia-340.conf.

[Regression potential]

Low, since it should move a blacklist file from /etc to /lib

______________________________________________________________

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.

someone turned up in #ubuntu+1 - they had nvidia-340.conf left after uninstallation

[Vitor Luis (exterminador)]

I've had exactly the same problem described above. Installed Nvidia drivers via via Additional Drivers and all was working fine.
After that I decided to remove the Nvidia drivers and rebooted the laptop. My screen resolution was set as 640x480, without any possibility of changing it.
Asking for help, on #ubuntu+1 @ Freenode, someone told me to check /etc/modprobe.d for a nvidia conf file. I've done that and it was there.
Deleting the file and rebooting the laptop solved the issue.

Status changed to 'Confirmed' because the bug affects multiple users.

[Kev Bowring (flocculant)]

apport-collect failed to collect new information for this bug as nvidia is no longer installed.

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.

[Kev Bowring (flocculant)]

Just booted xubuntu 17.10.1 iso - installed nvidia with software-properties - additional drivers.

Blacklist file added.

Removed nvidia with software-properties - additional drivers.

Blacklist file removed.

[Adam Conrad (adconrad)]

This is very much a bug in nvidia-graphics-drivers-340. One can debate if software-properties should or shouldn't purge (though traditionally, the argument was that silent frontends shouldn't purge because the user hasn't explicitly asked for that), but if a removed package's unpurged conffiles cause the system to misbehave, that package needs to be rethought to avoid that situation.

[Adam Conrad (adconrad)]

The real answer here is we should rm_conffile those files in /etc and ship them in /lib/modprobe.d instead.

[Doug McMahon (mc3man)]

As stated in duped bug removing nvidia drivers (nvidia-390 here) via software-properties only removes the driver meta package so actually nothing is removed.
(- and of course /etc/modprobe.d/nvidia-graphics-drivers.conf will still be there ..

[Alberto Milone (albertomilone)]

@Doug: I'm working on the meta-package part for LP: #1753333 , this is a separate bug report, only about the blacklist file.

[Iain Lane (laney)]

Alberto, can you have a look to see if there's anything to be done for -340 in bionic please?

[Alberto Milone (albertomilone)]

@Iain: a backport is in the plans.

[Timo Aaltonen (tjaalton)]

Hello Kev, or anyone else affected,

Accepted nvidia-graphics-drivers-340 into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/340.107-0ubuntu0.18.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Kev Bowring (flocculant)]

@tjaalton - thanks - all done and tagged

[Łukasz Zemczak (sil2100)]

What packages and versions have been tested during verification?

[Łukasz Zemczak (sil2100)]

Seeing the urgency of the package being blocked in -proposed, I'll be releasing it conditionally without test version number.
