I searched for hours and tried several solutions but I'm still stuck and I'm not sure to have everything working properly.

The situation is the following:

Output of uname -a:

Linux rocco 5.4.0-28-generic #32-Ubuntu SMP Wed Apr 22 17:40:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Ubuntu 20.04

The driver seems installed correctly

BUT:

Output of more /usr/share/X11/xorg.conf.d/10-amdgpu.conf:

Output of nvidia-settings:

ERROR: Unable to load info from any available system
(nvidia-settings:5784): GLib-GObject-CRITICAL **: 23:19:26.837: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

I think I should have seen a list of options in this panel.

optirun --status does not say nothing
chrome://gpu is reporting only my Intel UHD Graphics 620

If I launch glxgears I cannot see any processes on nvidia-smi

At the end I'm not sure if I'm using the nvidia drivers or not.

Any suggestion would be appreciated.

Goto software & updates then the additional drivers tab Under your GPU make sure you select the one that says proprietary, tested and hit apply changes
