I'm new here and will be thankful if you help me in this case. I dunno why, but somehow I did upgrade video driver and now I want to restore the original one for current system. Is this safe and is it work if remove/purge libraries one by one, and then install them again with commands like that:

$sudo aptitude remove libegl-mesa0:amd64
$sudo aptitude install libegl-mesa0:amd64

So I want to remove these which are 18.3~git to the 18.0.5

$ dpkg -l | grep mesa

  • The following answer is somewhat related. However, the specific versions mentioned are different so the exact commands used will not work but you can get an idea on how safe or unsafe it may be based on how much work you want to do. https://askubuntu.com/questions/908064/dependency-problem-while-removing-oibaf-and-paulo-dias-repositories – mchid Dec 17 '18 at 00:38

Thank you guys! It was helpful! This is what I've did: First checks all packages contains oibaf

$ dpkg -l | grep oibaf

Then I checks for recommended version

$ apt policy <package-name>

And finally does install with specific version

$ sudo aptitude install <package-name>=version

Voiala, no more oibaf. My end goal was to upgrade system to 18.10 cosmic and it's done

From the package names, or from something like apt-cache policy mesa-va-drivers | grep -C2 Version, we can see these packages come from the Oibaf repository.

To revert to the default packages you need to ppa-purge those repos.

sudo apt install ppa-purge sudo ppa-purge ppa:oibaf/graphics-drivers

Should revert you to the default repos and install the default packages.

In my experience the Oibaf and PKPPA repos do go bad sometimes, but usually are back to being usable within a couple of days. If it's just the latest updates that have gone wrong then it's possible to backtrack to prior versions (GUI tool Synaptic, and CLI too Aptitude both are good for that).
