<pre>Can we get a full binary DPCD dump please?
dd if=/dev/drm_dp_aux1 > dpcd
If that returns an error then you will have to use ddrescue instead of dd.
Uncompressed the complete dump should should 1MiB in size. Probably want to
compress it with gzip before attaching.
Also can we get a copy of the EDID as well? This needs to be done with the
kernel where the display still works.
cat /sys/class/drm/card0-DP-2/edid > edid</pre>
