I should mention, I am using Fedora Core 15 and the evdev driver. --Scott

Both devices currently come up, however I need to apply a coordinate transformation matrix to the input, as documented here: http://lists.freedesktop.org/archives/xorg/2010-April/049967.html This works fine from the command line, however I have a pair of devices. The touchscreens are uniquely identified via usb port with udev, so I have hardcoded /dev/input/ts1 and /dev/input/ts2 devices. However, I cannot script the xinput command, as I do not know which devices are which from the xinput list output. Each touchscreen reports two device ids: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ stylus id=6 [slave pointer (2)] ⎜ ↳ eraser id=7 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=14 [slave pointer (2)] ⎜ ↳ HID 0430:0100 id=11 [slave pointer (2)] ⎜ ↳ TS Device id=12 [slave pointer (2)] ⎜ ↳ TS Device id=13 [slave pointer (2)] ⎜ ↳ TS Device id=14 [slave pointer (2)] ⎜ ↳ TS Device id=15 [slave pointer (2)] Is there a way to define the matrix in the xorg.conf file, or a way to match the ids above to their /dev/input device or USB port?
