Uninstall ppa-mesarc

[Hoshi98]

Good day. I install ppa-mesarc on Ubuntu 20.04, thankyou.

Now I want to completly Uninstall this ppa.

Could you give the steps to remove it?

The reason is that i want default graphics drivers same as before. Then i will install corectl without the driver updates.

Thankyou for the work.

There's lots of ways to do this. For example: https://itsfoss.com/ppa-purge/

You can even just download the correct CoreCtrl deb and install without even enabling the PPA: https://launchpad.net/~ernstp/+archive/ubuntu/mesarc/+packages

Hello, Just to say I needed to do this today:

And so here's an example terminal output of what it looks like (to do this relevant PPA Purge operation!)

# 1. ensure that the PPA exists, and is valid (maybe can skip, otherwise to add it back)
sudo add-apt-repository -y ppa:ernstp/mesarc

# 2. run 'ppa-purge' command
sudo ppa-purge ppa:ernstp/mesarc

This operation idk YET if has fixed my issue, until I can reboot the system. However quite clearly it needed to be done, to remove these broken pkg conflicts. That had utterly broken my system,

The TLDR is - don't use this PPA. It is pretty high chances of damaging the system. Or many people install the oibaf mesa. Which is also quite high chances of breaking things. Important things!
