I installed 19.10 on a new Lenovo x1 Extreme.

I am unable to use an external display with either usb-c or hdmi. Only one display shows up in Display Settings. There is no movement in dmesg when connecting second display.

Proprietary drivers are installed (nvidia-driver-435).

My problem is that I cannot switch between NVIDIA gpu and Intel gpu. I am able to make different choices in the "NVIDIA X Server Settings" app. But, even after reboot these changes are not reflected in Settings -> Details which always says "Intel® UHD Graphics 630 (Coffeelake 3x8 GT2)".

$ sudo lshw -c display
