The xrandr output stops reporting that there are DVI-D-1 and HDMI-1

Show the output to us, please?
Sure. Here's the xrandr output with a newer kernel, where it's not working:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200

1600x1200 0.00*
800x600 0.00
640x480 0.00
And here it is from an older kernel where it's working (I removed a
bunch of the modelines to shorten it):
Screen 0: minimum 320 x 200, current 3760 x 1600, maximum 16384 x 16384

You shouldn't have the Radeon driver installed at all. That's
for a different manufacturer's boards.
Right. Don't know why I got Radeon stuck in my head.
You should have either nouveau or NVidia drivers installed.
Nouveau is open source. NVidia is closed-source.
The nouveau driver is installed in both cases.
Together with that, you need the Kernel Modesetting driver.
Don't know what this one is. Is it something new that began with the
5.6.0 kernel?
I suspect what you're seeing is a lack of correct driver,
leading to a fallback to VESA standards.
While the nouveau driver is installed, there is a difference. Don't know
what it means. Running lsmod | grep nouveau I get (non-working):
nouveau 2318336 0
video 53248 1 nouveau
ttm 118784 1 nouveau
drm_kms_helper 249856 1 nouveau
drm 606208 3 drm_kms_helper,ttm,nouveau
mxm_wmi 16384 1 nouveau
i2c_algo_bit 16384 2 igb,nouveau
wmi 36864 3 wmi_bmof,mxm_wmi,nouveau
button 24576 1 nouveau
vs (working):
nouveau 2273280 2
video 53248 1 nouveau
ttm 122880 1 nouveau
drm_kms_helper 233472 1 nouveau
mxm_wmi 16384 1 nouveau
drm 585728 5 drm_kms_helper,ttm,nouveau
i2c_algo_bit 16384 2 igb,nouveau
wmi 36864 3 wmi_bmof,mxm_wmi,nouveau
button 24576 1 nouveau
That 0 on the nouveau driver line in the non-working version means
no-one is using that driver, yes? Could be a sign of what's going wrong
but I don't know where that lead takes me.
