Thanks for your feedback. The justification mainly revolves around a patch that I saved for later - one that enables pentablet mode for use with a stylus, which relies on advanced mode. I'll include that patch when I come to resending them all after this review, so that everything is clear. But we don't actually want to use it as a tablet, we want to use it as a mouse pointer (since the touchpad way of using the mouse is not very reliable) - i.e. we want it to be relative. I experimented and enabled it in absolute mode, but I couldn't find any way of making X treat it as relative. It still "behaves absolute" even with this command: xinput set-mode "OLPC HGPK ALPS HGPK" relative We want it to behave relatively, i.e. if I finish my stylus movement in one place and continue from another, the mouse cursor should not jump. Does this act as justification for doing the relative calculations in the driver, or is there an option that I'm missing?
