I have installed the latest nvidia driver on my ubuntu 20.04 but when I try to run the command nvidia-settings I get this message and the software opens a blank window
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
(nvidia-settings:4940): GLib-GObject-CRITICAL **: 14:24:42.631: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed
** Message: 14:24:42.634: PRIME: No offloading required. Abort
** Message: 14:24:42.634: PRIME: is it supported? no
When I try to use the command nvidia-smi I get this other message
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Someone help me, I have tried many tutorials but nothing happens.
