Bug Description
Regression with Ryzen 3 2200G, UEFI Asrock B450 Pro4 motherboard and 55-75 Hz monitor.
Booting Xubuntu 19.10 live iso with safe graphics options did give a stable desktop display, but
xubuntu@xubuntu:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 77.00*
xubuntu@xubuntu:~$
The monitor is only supposed to have a maximum vertical refresh rate of 75 Hz. 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".

I was supporting another Xubuntu 19.10 user on AMD Ryzen 3 2200G (Gigabyte Technology Co., Ltd. B450 AORUS M/B450 AORUS M, BIOS F2 08/08/2018) today, whose log of a failed (standard) boot (to black screen) showed
kernel: WARNING: CPU: 2 PID: 255 at drivers/ gpu/drm/ amd/amdgpu/ ../display/ dc/dcn10/ dcn10_hw_ sequencer. c:932 dcn10_verify_ allow_pstate_ change_ high.cold+ 0xc/0x23d [amdgpu]
