Hi,
I am trying to implement something like this: hotpluggable dummy monitor. I copied it but it does not work as I do not have any card* inside /sys/class/drm/ (I only have a file called version), so I found this answer: check hdmi status but again it does not work as I don’t have a switch folder under virtual.
This is the output of xrandr before following the instauctions in the first link:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 600mm x 340mm

720x400 70.04
640x480 59.94 59.94
DP-0 disconnected (normal left inverted right x axis y axis)
After trying to follow those instructions, I get:
xrandr: Failed to get size of gamma for output default

Is there an alternative way to check for the HDMI status?
Thank you
