I have a Dell Latitude E6420 laptop that has a vga and hdmi port, and I was able to run 2 additional monitors in a addition to the laptop built in display using 20.04.
After upgrading to 22.04, only the VGA monitor shows up in the display configuration.
The Settings-> About-> Graphics shows "NVIDIA Corporation GF119M [NVS 4200M] / Intel® HD Graphics 3000"
The dell website shows system configuration for the laptop shows nVidia NVS 4200M 512MB DDR3 Di screte Graphics, Dell Latitude E6420.
It seems that the hdmi port is not found.
xrandr only shows the vga and the laptop built in display.
