Hi Guys,
I have exactly the same problem. My system deesn't produce any event when I
plug or unplug my HDMI/DP cable. I've noticed that about a year ago after
one of my Debian Wheezy (used to testing distro, now it's Debian stable)
upgrade.
I started to dig around this issue several days ago. I even flashed the bios
of my server, tried to dump EDID information and force Xorg to use the
monitor info, but I've found only solution for NVidia (change DP1 to correct
interface)
Option "ConnectedMonitor" "DP1"
Option "CustomEDID" "DP1:/etc/X11/edid.bin"
Option "IgnoreEDID" "false"
Option "UseEDID" "true"
But I don't have Nvidia card and use Intel driver for my HD 2000 module in
Intel Core i7 Sandybridge processor.
Anybody can help?
Maybe you know kind of workaround.
I've read some information about passing some parameters to gdm(?) module
options drm_kms_helper edid_firmware=edid/1280x1024.bin
But I haven't tried it yet.
Any other ideas?
