No, you're doing everything correctly. The kernel gives each input device an ID which increases with every new device. > If this changes everytime I run the driver, how do I create a entry > in xorg.conf to use? Should I be using udev to create a symlink? If you have a hal-enabled xserver, it should pick up new devices automatically. If you want to use xorg.conf, the best way is to refer to the device by bus/vendor/product or the unique identifier. Your device doesn't seem to have a unique identifier, but maybe it's not possible in uinput. But if your bus/vendor/product is always the same, simply use that. Another way is to use udev to automatically assign fixed names to devices, so that you can use Device "/dev/input/xyz" in xorg.conf. But again, no idea if udev works on uinput devices. tom _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
