Hi Luca,
Thank you for your suggestions! I did run through your post and eventhough I installed the driver, and blacklisted nouveau, I have an issue after the line
The terminal prints that that file does not exist, and the other command succesively.
Even when running nvidia-setting, the computer yields:
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
(nvidia-settings:4661): GLib-GObject-CRITICAL **: 10:06:23.039: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 10:06:23.041: PRIME: Requires offloading

** Message: 10:06:23.065: PRIME: is "on-demand" mode supported? yes
and still, nvidia-smi yields the same original output. Thank you for your help, though!
