Annoyingly my NVIDIA installation from RPM-Fusion is (again) not working.
I noticed (under GNOME) that my system is not using the NVIDIA driver at all.
I first noticed on Fedora 30 so I uninstalled NVIDIA, upgraded to Fedora 31, reinstalled NVIDIA - but still nothing.
My System is a XPS 15 9550 with the internal Intel GPU and an additional GTX 950M.
With the optimus active it would be use Intel GPU with low demand and Nvidia GPU with high load, and it would be done automatically to do sure a good balance between power saving and performance. About optimus manager or bumblebee I don’t know because i don’t use a nvida card and either a hybrid GPU but always read about problems about bumblebee there are users more expert about this theme and a exits good information in the net about it.
In this point if you are interested in a easy change between both GPU you should try install this package “mate-optimus” than looks like it should work also in gnome if we look the dependencies, look very simple to do the change look this article, But this is some thing than i don’t know at all.
[jorge@fedora31 ~]$ LANG=C sudo dnf install mate-optimus
