Hello,
Could you please help me to get one of HDMI output flipped/reflected/mirrored - display connected to the HDMI out will be used with mirror and therefore picture should be flipped/reflected/mirrored before so after a mirror picture looks normally.
I tried video=HDMI-A-1:reflect_y - but it does not help.
I see nothing in logs - is it possible to enable debug DRM logs before boot?
Thank you in advance!
