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 )
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 )
