Got a brand new thinkpad p1 gen4. Installed Ubuntu 21.10. Everything worked like a charm. Never expected it to be so smooth. Even bluetooth worked. Didn't believe it.

So I had only one step to do. Install Nvidia drivers. Used autoinstall. And surprise, surprise it broke something. Multitouch gestures stopped working. Spend multiple hours to realize it. Another drivers didn't help.

Anyway for me the general question was. How do I revert apt get commands? It seems kind of difficult. I could purge all nvidia stuff or whatever. BUT is there maybe some general solution? That is the reason I'm always afraid of apt upgrade. It may break something and I have no idea how to restore. But maybe it's just a newbie question. Is it?
