Confirm that Secure Boot is disabled in your BIOS. (You may be able to re-enable it again at a later time).
Note: If you created /etc/X11/xorg.conf, please delete it (sudo rm -i /etc/X11/xorg.conf
), and then log out.
The Nvidia drivers don't work well with Wayland. We'll change to X11/Xorg. Log out. Then, at your login screen, select your Username, then click on the icon in the lower-right of your screen, and select Ubuntu on X11/Xorg, then enter your password to continue logging in.
Start Firefox
and open a few tabs (eBay, Amazon, etc.), then in terminal
...
$ nvidia-smi
(note that in my example, Xorg, gnome-shell, and Firefox are accelerated)
