Anyway for calibration on dual screens?
Is there anyway to calibrate GfxTablet so it can work on dual screens setup?
Right now I’m using it on ArchLinux it is working fine except that the canvas is stretched to cover both of my screen (that is about 3200 pixels wide! ) and as you can expect it is really sensitive to the slightest movement.
When you move your “mouse” on your tablet from the far left to the far right, it should go from the left monitor to the right.
If that is the case then the problem is, that what you are requesting is not possible, because your Tablet is not capable to just higher the dpi of the touchscreen!
