The cpu/gpu is Ice lake, you need at least kernel 5.3 and updates from
bionic-proposed to libdrm, mesa and xserver, or use Ubuntu 19.10.
18.04.4 image will be released early next year and that will support Ice
Lake.

Title:
Intel graphics card not detected and reverts to llvmpipe
Status in xorg-server package in Ubuntu:
Invalid
Bug description:
[Impact]
Ubuntu 18.04 install (also seen on 16) is unable to detect integrated Intel
graphics card (Intel Iris Plus). Using a Dell XPS 13 2-in-1 7390 the machine is
unable to detect attached monitors, change resolutions, or adjust brightness.
[Information]
There is a dual boot Windows 10 partition, which can access the integrated
graphics card without issue and connects to attached monitors on boot.
Reinstallation following destruction of the W10 partition reveals the issue is
unaffected by this duality.
