I am trying to plug an external monitor to my laptop with a HDMI cable in order to have a dual screen.
When I do so, nothing happens, the external screen is not recognized at all. I think that's because the driver of my laptop's video card is not properly installed/enabled.
To install the drivers, all I did was
sudo add-apt-repository ppa:graphics-drivers/ppa
and then used 'additional drivers' GUI to setup nvidia-driver-430 on my system.
I rebooted my machine and nothing changed, the external monitor is still not recognized...
When I try to launch nvidia-settings, I get this error :
ERROR: Unable to load info from any available system
(nvidia-settings:3585): GLib-GObject-CRITICAL **: 17:36:06.267: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 17:36:06.271: PRIME: No offloading required. Abort
** Message: 17:36:06.271: PRIME: is it supported? no
Here's the output of nvidia-smi :
