I would like to setup the dual monitor settings where I can use two monitors as a single Desktop with single panel, single launcher and when some programs are maximized then it should span both the monitors (i.e fullscreen over both the monitors)
I have ATI raedon graphics cards and after searching it in the internet I found that by configuring the xorg.conf file I can setup the settings that I want.
I have tried several ways to do it i.e
using gksu amdcccle
And setting MultiDisplay settings , but my requirement has not yet been met.
I have done this using Nvidia graphics but its seem that it doesnot work with ATI graphics card.
After searching for a while I found the link which gave me hope that it can be done in ATI as well , According to this link
xrandr must be disabled and AMD catalyst center will give the extra option of Big Desktop, to set it I used
sudo aticonfig --set-pcs-str="DDX,EnableRandR12,FALSE"
Then I restart X as per that link
But this command gives this output to the stdout
SetPcsStr is exclusive, other options will not be used.
And I didnot find any extra configuration in my xorg.conf file.
And I didnt even get the Big Desktop option in the AMD Catalyst center's Display manager. There is still three options i.e
Single Desktop Cloned Display Multiple Display
