Hi, I have two graphic cards on my LAPTOP: Intel HD630 and GT1050M. I have also laptop screen + external monitor, my problem started with that I had a problem with nvidia settings which caused an error:

Code: Select all

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:2792): GLib-GObject-CRITICAL **: 19:13:16.865: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 19:13:16.867: PRIME: No offloading required. Abort
** Message: 19:13:16.867: PRIME: is it supported? no
I resolved it with deleting /lib/modprobe.d/blacklist-nvidia.conf and running sudo update-initramfs -u

Now I got problem that my external monitor is detected and it's chosen as main screen, but I can't detect my laptop screen... On windows it works correctly.

Thanks

I think problem is that one monitor starts on Nvidia card and internal (laptop screen) runs on Intel card. Because after prime select intel I got detected two screens but I can't switch on external, internal has working.

On most laptops, the HDMI port is internally connected to the Nvidia GPU, so it needs to be selected to use that port. When the Nvidia Settings utility is opened, any display connected to the Intel GPU will be named a PRIME display.
