VGA distributor hardware detection

Hi,

I am trying to find the monitor information attach to my system. To get the detail I have decoded the information available in edid file using edid-decode utility.

The file is available at /sys/devices/pci0000:00/0000:00:01.0/drm/card0/card0-VGA-1/edid

After decoding edid file I get the attached monitor details. Now I have situation where I am using VGA distributor which split the signal and I can connect multiple monitor through it.After doing this I am still getting the same monitor information in my edid file.Second monitor detail is missing from it. I try to restart the system and found that file empty edid file is generated if two monitor is connected.

I have concluded that after starting the system some utility is actually creating the edid file but I am not sure which one is doing this.

Can anyone let me know how to detect if multiple monitor is connected to my system through VGA distributor ? I am using Ubuntu 14.04 on HP machine.

Any help or suggestion is highly appreciated. Smilie



Thanks

dbus-monitor(1) 					      General Commands Manual						   dbus-monitor(1)

NAME
dbus-monitor - debug probe to print message bus messages SYNOPSIS
dbus-monitor [--system | --session | --address ADDRESS] [--profile | --monitor] [watch expressions] DESCRIPTION
The dbus-monitor command is used to monitor messages going through a D-Bus message bus. See http://www.freedesktop.org/software/dbus/ for more information about the big picture. There are two well-known message buses: the systemwide message bus (installed on many systems as the "messagebus" service) and the per- user-login-session message bus (started each time a user logs in). The --system and --session options direct dbus-monitor to monitor the system or session buses respectively. If neither is specified, dbus-monitor monitors the session bus. dbus-monitor has two different output modes, the 'classic'-style monitoring mode and profiling mode. The profiling format is a compact for- mat with a single line per message and microsecond-resolution timing information. The --profile and --monitor options select the profiling and monitoring output format respectively. If neither is specified, dbus-monitor uses the monitoring output format. In order to get dbus-monitor to see the messages you are interested in, you should specify a set of watch expressions as you would expect to be passed to the dbus_bus_add_match function. The message bus configuration may keep dbus-monitor from seeing all messages, especially if you run the monitor as a non-root user. OPTIONS
--system Monitor the system message bus. --session Monitor the session message bus. (This is the default.) --address ADDRESS Monitor an arbitrary message bus given at ADDRESS. --profile Use the profiling output format. --monitor Use the monitoring output format. (This is the default.) EXAMPLE
Here is an example of using dbus-monitor to watch for the gnome typing monitor to say things dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'" AUTHOR
dbus-monitor was written by Philip Blundell. The profiling output mode was added by Olli Salli. BUGS
Please send bug reports to the D-Bus mailing list or bug tracker, see http://www.freedesktop.org/software/dbus/ dbus-monitor(1)
