I've got a planar PX2230MW and an HP 2011x in a dual configuration. I'm using twinview in the nvidia-x settings. When I touch on the far left on my planar the mouse is right under my finger, however when i slide it to the right the mouse speeds up and ends up on the far side of the HP monitor. I've tried using xinput-calibrator to fix it but when I open it the program is stretched across both monitors. Is there a way I could fix this?
