After upgrading to Ubuntu 18.04 from version 16.04, the external monitor is not detected anymore. I have tried using both VGA and HDMI monitor ports to connect using the USB-C adapter to my laptop. Also, I have tried with two different monitors and two USB-C adapters.

Specs:

• Dell XPS 9370


• Ubuntu 18.04.1


• Intel UHD Graphics 620 (Kabylake GT2)


• kernel 4.18.0-15-generic

What I've tried:

• Reinstall and use lightdm instead of gdm3 as explained here: External monitor not detected on Ubuntu 18.04




• Force VGA output when it shows disconnected as explained here: Can I force VGA signal output even when xrandr shows 'disconnected'?

Any recommendations? Could this be a hardware failure?

EDIT(s):

• Added the xrandr --verbose output


• More information about what I have tried

Try this:

sudo xrandr --output HDMI-1 --auto

sudo xrandr --addmode HDMI-1 1920x1080

sudo xrandr --output HDMI-1 --mode 1920x1080 --pos 0x0

Also you can use a GUI for xrandr:

sudo apt-get install arandr

Last try is to install latest nvidia drivers for the xserver:

sudo add-apt-repository ppa:graphics-drivers

sudo apt-get update

sudo apt-get install xserver-xorg-video-nvidia-410 nvidia-*

In your case upgrade the intel drivers:

sudo apt-get upgrade xserver-xorg-video-intel -y 



sudo reboot
