Xorg Setting checking from Command Line
How do I determined, whether Xorg is using
Xinerama, DDC and Reduced Blanking ??
Just adding few options in Xorg.conf is sufficient ?
If I have to check from command-line, then how can I check above mentioned settings ?
(I am using VIA chipset and Dell DELA07A monitor, Just in case this info required )
EDIT:
If I execute the command: Xorg -extension ?
It gives me the output as
[mi] Extension "?" is not recognized
[mi] Only the following extensions can be run-time disabled:
[mi] Generic Events
[mi] Composite
[mi] DAMAGE
[mi] DOUBLE-BUFFER
[mi] DPMS
[mi] GLX
[mi] MIT-SCREEN-SAVER
[mi] MIT-SHM
[mi] RANDR
[mi] RENDER
[mi] SECURITY
[mi] X-Resource
[mi] XFIXES
[mi] XINERAMA
[mi] SELinux
[mi] XTEST
[mi] XVideo
As per the above output, I assume that it is possible to enable/disable extensions in runtime. Question is HOW ?
If it is really possible then I can enable/disable the XINERAMA extension as and when I want
I also assume that when XINERAMA is ON in dual-head then maximizing an open application will span on both monitor.
And when XINERAMA is off then maximizing an application will span to one monitor only. ( Correct me if I'm wrong )

You can check for the Xinerama extension being present by xdpyinfo| grep XINERAMA. To get the settings of the Xinerama extension you can use xpdyinfo -ext XINERAMA
About reduced blanking: you can show the modes the Xserver knows about by calling xrandr --verbose and examining the current one. Using the cvt tool you can generate modelines with/without reduced blanking for your desired resolution and compare those to the ones you see in xrandr output.
DDC information: I am not really sure. Maybe have a look at the X log file. With the mentioned xrandr --verbose you can also see the EDID of connected monitors.
Update: I just found https://wiki.ubuntu.com/X/Troubleshooting/Resolution where a tool called ddcprobe is mentioned. So - without knowing it - I want to add that to the list.
