Instead of technical issues, troubleshooting and those annoying things, I just want to share with you all a pleasant surprise.
I had my gaming/work laptop a bit abandoned, so I just wanted to clean the dust and work a bit with it. I sadly had to format my clones/linux_backup external hard drive, so I had to get an old KaOS clone I had from Dec'18, so restored it and faced this scenario:
Octopi
upd
SysInfo

So I did it, fixed the annoying config files to be able to use my GeForce properly and, to my astonishment, everything frigging worked. No issues, no freezes nor annoying bugs... I just works:
Updated

So here I am with an updated and shiny KaOS again. Gonna save a clone, just in case! Cheers!
