Tested with:

- Ubuntu 24.04 (kernel and firmware as provided in installer, KDE Plasma 5)
- LG 34UC88-B display
- LG 27UK500 display
HDMI behavior is quite strange (and both displays work fine when connected directly to FW16 using an HDMI expansion card) - sometimes the display will be detected, but with only 640x480 resolution available; other times the laptop locks up and has to be power cycled when the display is attached to the dock.
