I have a problem with plugging my Monitor/TV (with both D-SUB and HDMI connectors - D-SUB/VGA works fine, HDMI is not detected) to my Debian media server.
The problem is when I plug either HDMI cable or DisplayPort adapter, connected to the same HDMI cable to my motherboard,
then system doesn't register any event. I've tried that using the following command:
(there isn't any new event)
I checked xrandr (using VNC server):
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
I checked directly what drm module registred:
and neither HDMI nor DP doesn't work.
Of course I've checked the cable and TV and I'm able to connect it to my laptop with NVidia Optimus and everything works.
But in case of my server I have only Intel HD 2000 build-in my Core i7 (Sandy-Bridge) processor and I use intel driver.
I've been digging in this problem for several days.
I fought I may force graphic card to see connected monitor:
Option "ConnectedMonitor" "DP1"
Option "CustomEDID" "DP1:/etc/X11/edid.bin"
Option "IgnoreEDID" "false"
Option "UseEDID" "true"
but these options only work for NVidia card. Btw. I had to dump edid data for that.
Another probe was flashing the Bios of my mainboard, because I've noticed some changes around HDMI in the bios changelog.
But that also didn't work.
I've noticed that there is an option in the DRM (DRM_LOAD_EDID_FIRMWARE) to force using EDID data from file, but I don't think that may be the good path.
Then I updated the kernel to the newest one (3.9.7). Almost the default for debian configuration didn't work as well.
Finally I've noticed that there is a special module in the kernel called
Samsung HDMI Driver (VIDEO_SAMSUNG_S5P_HDMI
) but I can't turn it on playing with make menuconfig.
I've stacked in VIDEO_SAMSUNG_SP_TV.
I can't find it and PLAT_S5P as well.

This is what I've found here:
HDMI. The auxiliary driver used to control HDMI interface. It exports its
subdev in its private data for use by other drivers. The following callbacks are
- g_mbus_format: returns information on data format expected by on HDMI input
The driver supports an interrupt. It is used to detect plug/unplug events in
kernel debugs. The API for detection of such an events in V4L2 API is to be
Anyone can help me with compiling this module?
