@Morten I think that all Ryzen motherboards are going to have UEFI firmware rather than the old BIOS firmware - even though everyone keeps using the old name.
If it is your computer and you know what you are doing you could turn off secure boot. If you don't know, then don't do it. I grabbed all of these files; CHECKSUMS CHECKSUMS.gpg linux-headers-5.4.0-050400rc7_5.4.0-050400rc7.201911102031_all.deb linux-headers-5.4.0-050400rc7-generic_5.4.0-050400rc7.201911102031_amd64.deb linux-image-unsigned-5.4.0-050400rc7-generic_5.4.0-050400rc7.201911102031_amd64.deb linux-modules-5.4.0-050400rc7-generic_5.4.0-050400rc7.201911102031_amd64.deb @Kai-Heng Rc7 is better than rc6, but not a lot. I might have imagined the part about the VGA port being reported as a VGA port. Sorry. That was probably when I had the graphics card plugged in. The VGA port is being reported as a second Display Port again. With a fresh install of Eoan Ermine Xubuntu, updates, and rc7; Standard boot gives a badly pixelated display for menus, moving windows, changing text; xrandr reports reasonable things, then after 10 or 20 minutes the machine locks up. Booting with safe graphics from the grub menu gives a stable display, but xrandr seems confused and only reports one mode with a 77 Hz vertical refresh rate, and no mention of any ports.

Xrandr reports 77 Hz as the only choice. The monitor reports 60 Hz, not that I trust the monitor. Swapping monitors and running many reboots the situation seems to be... Old versions of Ubuntu (Bionic and Dingo) can handle the hardware. Standard boot sometimes gives a blank screen. Standard boot sometimes gives a badly pixelated display (Ctl-Alt-F6, Ctl-Alt-F7 temporarily improves it). Connecting a 144 Hz monitor convinces something (the firmware?) that fast refreshes are OK on a slow monitor, or at least it fails to reread and abide by the slow monitor's limitations when swapping back. Something, I don't know what, convinces the computer to run the display at 60 Hz, sometimes. The motherboard has three video ports; DP, HDMI and VGA (using an onboard DP? to VGA converter chip). The fast monitor has DP, HDMI and VGA ports, but I only experimented with the DP connection. The slow monitor has VGA and DVI-D ports. I experimented with VGA to VGA and HDMI via a passive adapter to DVI. When running in the badly pixelated mode xorg seems to think that the VGA port is "DP-1".
