I have been running Ubuntu for years now with only LTS upgrades. root and /home are separate partitions so I have always kept /home and that served me fine until now. There is only the one user, myself. Since the upgrade to 20.04, there are multiple issues with this user though. Sleep mode is wonky and unreliable, the NVIDIA graphics driver can't be installed since a kernel update, some audio settings don't last beyond a restart. When I create another user, then everything works just fine over there. I strongly suspect that some old config files from way back when are causing me issues, especially since Snaps are a thing.
Now, I could of course delete everything, create a whole new user for myself and then play everything back from a backup, which would take hours.
Or is there a way to 'rejuvenate' the user settings so that it acts like a fresh system, except my personal files are still there? I have found a way to reset Gnome but apparently the issue lies deeper than that.
I would appreciate any suggestions.
