How to unistall OpenGL drivers(?)?


I tried to install the Mesa Drivers but I installed the OpenGL Drivers.

Maybe I got it wrong, but in my attempt to download and search for them, I do not find them. I probably installed OpenGL and now I want to go back to those of nvidia.

I had followed these instructions.

zartilas@zartilas:~$ glxinfo | grep Mesa

zartilas@zartilas:~$ glxinfo | grep OpenGL
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: NVIDIA GeForce GTX 1650/PCIe/SSE2
OpenGL core profile version string: 4.6.0 NVIDIA 470.86
OpenGL core profile shading language version string: 4.60 NVIDIA
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6.0 NVIDIA 470.86
OpenGL shading language version string: 4.60 NVIDIA
OpenGL context flags: (none)
OpenGL profile mask: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 470.86
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

First question. Why would you install the mesa driver of nvidia? The one you use from nvidia is far superior.

I do not disagree with this and that is why I want to return.

The link you provided shows you how:

sudo apt install ppa-purge && sudo ppa-purge ppa:kisak/kisak-mesa

Remove it and go back to original Mesa driver

If you are facing issues and do not want to use the newer version of Mesa, you can revert to the original version.

Is this not to go to a previous version or did I not understand well?

Performing the above will go to the previous version (What comes with Zorin OS).

Thank you.

This returns me.

ppa-purge is already the newest version (0.2.8+bzr63).
The following packages were automatically installed and are no longer required:
  libllvm12 libllvm12:i386 zorin-os-feedback
Use 'sudo apt autoremove' to remove them.

Everything looks good, but there are a couple of things to fix:

These repositories are not applicable to Zorin OS 16 (Focal fossa).
Please open Software & Updates application. Move to the "Other Software" tab.
Read through to list to find the first repository, then click and and then select the Remove button to remove that repo.

Repeat the above for the second repository.

Once completed, close Software & Updates and open a terminal.

sudo apt clean && sudo apt autoremove

sudo apt update && sudo apt dist-upgrade

I found this! I'm asking for confirmation.

Yes, select remove on that.
Then, look for java-non-latin-shortcuts/ubuntu and remove it, too.
Then remove precise

Once done, follow the steps above to clean apt and autoremove, then update and upgrade.

Delete both?


No, that one should stay.

How did precise get added to your sources.list?
Can you navigate to /etc/apt/sources.list.d/ and take a look there for a File for that repository?

oooo no, I deleted them. :joy: :sleepy:

Well, you're in trouble, now. :stuck_out_tongue:

The Canonical Partners option can be re-added easily.

Click the add button in "Other software" and paste in

deb focal main

0 bytes size, eh?
I would just delete those that you have highlighted.
(all four files).

How do I know it came back?

It shows 0 bytes in size.

I am not given the option to delete them.
