I have a Dell XPS desktop with Deepin Linux where the onboard HDMI doesn't work (no signal).
Based on the Ubuntu collected from Ubuntu, Deeping is not identifying some HDMI ports (uname/xrandr/lshw from both systems below)

I have tried many different approachs that did not work, and need to fix this.
