Exclamation Dual head setup with one touchscreen stretching over non-touchscreen display


Hi there

i'm facing a problem with configuration of dual head setup.
Got a eGalax touchscreen cover over one monitor 1440x900 connected to VGA-0 and one HD-Ready TV connected to HDMI-0 with 1280x720
The graphic card is using radeon kernel module and touchscreen using evdev.
Touchscreen is calibrated and as far as i'm using one monitor (with touchscreen) everything is fine.

The problem is when i connect the TV and setup via xrandr TV beside the monitor the damn thing stretches mapping area of touchscreen over the whole "virtual desktop".

I don't use any xorg.conf because udev or whatever else (Xorg itself) is doing the config on the fly perfectly setting the right resolutions to monitor and TV.
The only config i'm using is /usr/share/X11/10-evdev.conf for calibration of touchscreen.
Code:
Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "SwapAxes" "on"
        Option "InvertY" "on"
        Option "Calibration" "61 1959 137 1891"
EndSection
xinput_calibrator goes crazy with this config as well

What i need is map the monitor to touchscreen only without mapping TV.
I'm using pure Xorg without any display managers such as gnome or kde etc on custom distro of debian linux wheezy because radeon drivers on squeeze was a no go...

Any clues? Urgent help needed!
Cheers and thanks in advance guys!
