Don’t know why, but few days ago I tried to move (again) to GNOME with clean install, found that Nvidia-utils conflicts with Nvidia-455xx-utils (IF I remember the error correct). Made a clean install of KDE, and now I can’t change to Nvidia on kernel 5.10 using optimus-manager.

This is strange, because before this adventure of mine to change to GNOME, optimus-manager was working on kernel 5.10 on KDE. Maybe I missed some step this time around??
I was also on testing that time around.
