My configuration is the result of the server install, plus the proposed
kernel above plus:
sudo apt-get install ^ubuntu-mate-core
(select lightdm when prompted).
After rebooting, the system comes up in graphical mode with a 1920x1080
viewport on a 2560x1440 screen buffer. It is useful for a few
USB issue with 4GB maxmem seems to be fixed.
2560x1440 resolution issue not fixed.

[ 70.898755] kernel BUG at
@Sebastien. I think the more likely root cause is that the Raspberry Pi
firmware release (https://github.com/raspberrypi/firmware) consists of a
32-bit and 64-bit kernel, and a 32-bit-only userspace. For sure there
are kernel modules missing (a reconciliation with the official kernel's
config
Also noticed that v3d.ko is not included as one of the kernel modules
int he build. This seems to cause Xorg to pick the VMware display
driver instead of the Qualcom display driver.

Public bug reported:
While using Ubuntu 19.10 with either MATE or GNOME, I can use only
1920x1080 resolution instead of the full 2560x1440. If extra pixels are
configured, they fall off the right side or bottom of the display and
are not visible. Reproduced on Raspberry Pi 4 with 3GB max
