There is some more misbehavior regarding ddcprobe: On an ASUS Pundit
with onboard NVIDIA graphics we get no output at all: "edidfail", but
with hwinfo we get all information - but we would like to use ddcprobe,
because it is a lot faster.
see the Attachment for outputs of ddcprobe, lspci and hwinfo.
Should I provide more information about hardware or software? All these
tests come from a pre-boot busybox environment, but on my laptop I have
a complete linux system running when ddcprobe fails.
