Here you go.

I run a test at 1024x768 over HDMI with nomodeset.

Please note xrandr complains:
xrandr: Failed to get size of gamma for output default

and there is no more file for edid:
cp: cannot stat
`/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-VGA-1/edid': No
such file or directory
cp: cannot stat
`/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-2/edid':
No such file or directory

logs attached.

Hope this helps,
alfonso
