Remove repository and it's packages

I enabled the development Xorg repo from Community Repositories to try out a package. I didn’t set it up with the right options, and ran zypper up, which updated a lot of X related packages, now my NVIDIA driver doesn’t work. I also have the NVIDIA repo enabled. How can I remove everything this repo installed then disable it?

Here’s the Xorg.0.log output:

You could disable the repository and then run ‘zypper dup’, but be
careful using this if you aren’t sure about it or have added extra


@chearn5. You posted this in Looking For Something Other Than Support.
But it seems that you want support on your installation setup. Why not at Install/Boot/Login? It is more likely that the install experts are sitting there.

Shall I move it?

Yes. This should do it
