How do I revert back from sudo add-apt-repository ppa:xorg-edgers/ppa?

Question

I tried to upgrade graphics by running following command:

sudo add-apt-repository ppa:xorg-edgers/ppa 
sudo apt-get update
sudo apt-get upgrade 

However, it caused me a serious problem loading the OS. How do I rollback these changes?

Answer 1

You can use ppa-purge as suggested on their launchpad page.

** Please use ppa-purge to remove this PPA. It is particularly recommended to do this before upgrading to a new ubuntu release! **

Thus, we'll install ppa-purge package:

sudo apt install ppa-purge
sudo ppa-purge xorg-edgers

What ppa-purge do ?

ppa-purge - Disables a PPA and reverts to the official packages if applicable. For example, if I added the xorg-edgers PPA and installed the Nvidia drivers, if I do a ppa-purge on said PPA, it would not only disable the xorg-edgers PPA but also revert the NVIDIA drivers from the one in the PPA to the official ones found on the official Ubuntu repositories.
