--- Comment #6 from Jari Tahvanainen <jari.tahvanainen at intel.com> ---
Valerio - I'm really sorry about this delay for getting back to you. I'm just
wondering here that can kernel do much on a case that one does not get "I'm
alive" kind of the signal from KVM switch. Have you tried to "wake up" channel
with xrandr? This might cause monitor to wake up (previously showing as
disconnected). Assumable you are having debug version on your machine, so you
should also be able to produce i915_display_info data (sudo cat
/sys/kernel/debug/dri/0/i915_display_info) on both fail and okay cases.
