How to unistall OpenGL drivers(?)?

Close the window, then open terminal

sudo -i


navigate back to /etc/apt/sources.list.d/ and you should now have the elevated permissions to remove files.

I deleted them. Meanwhile when I run the command

glxinfo | grep Mesa

the OpenGL appears again

Which command?
As I understood it, you were reverting back to the original OpenGL, not removing it entirely.

Also, what is your end goal? Ignoring OpenGl, what are you trying to achieve?

I just have to go back to the nvidia drivers because I installed the mesa-opengl drivers and I have some issues with some applications.

Ok, what happens if you install the Nvidia Drivers directly? or use

sudo ubuntu-drivers autoinstall

You can check the available drivers in Software & Updates > additional drivers tab.
You can directly install a nvidia driver by number, if needed.
For example:

sudo apt install nvidia-driver-460

You can also use the BETA drivers:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo ubuntu-drivers autoinstall

Reboot to test.

I'm confused, so I cannot remove the openGL?
