dmesg when it doesn't work - drm-intel
And here dmesg when the monitor remains off.
One thing I can notice is that this dmesg contains these lines
[ 4.166745] [drm:intel_power_well_disable] disabling power well 2
[ 4.166751] [drm:intel_power_well_disable] disabling DC off
[ 4.166757] [drm:intel_power_well_disable] disabling always-on
and they are not on the other.</pre>
