I have installed the xserver-xorg-video-intel package but cannot detect monitor

[Dominic Jaques]

The monitor U2414H is not detected by Ubuntu, the graphics card displayed in settings is llvmpipe (LLVM 8.0, 256 bits). I believe it should be "Intel Iris Plus Graphics", which is what shows up in Windows Device Manager (my device is set up to dual boot).

It appears your i7-1065G7 processor is too new for Ubuntu 18.04 to support.

To fix this please try installing Ubuntu 18.04.3 instead:

or Ubuntu 19.10:
