Hi,

I am having a development linux box that has two screens (each of 1024x768, one is touchscreen). I am running a kiosk style application there, so I used xrandr to setup the screen.

I've noticed that instead having a :0 and :1 display it expands the :0 display to add up the full width of the screen from 1024x768 to 2048x768. Is there a way to achieve the separation of screens, like having different display (not mirroring) in the first screen and something else in the second screen, but each screen to be the physical monitor?

Yes you can, but i think not with xrandr.
Seems no-one see’s any value in separate screens anymore...

The :0 and :1 notation refers to separate “displays” (requiring an xserver instance on each).
I haven’t done this, but presumably instructions exist.

There is also separate “screens” denoted like :0.0 and :0.1 etc. (zaphod mode).
This is set up using an xorg.conf file and i find it useful for running video on a big screen without having it interrupted by switching virtual desktops etc on the other screen etc.

One of these should work for your use case.
