i've just pushed changes to the olpc-2.6.31 branch that let one do exactly this, so it should appear in the next F11-on-XO1 release for people to play with. it's lightly tested, but seems robust enough for a first pass. the only UI consists of: echo [1|0] > /sys/devices/platform/i8042/serio1/ptmode to turn pen tablet mode on or off. you can also add a a file to the /etc/modprobe.d directory containing "options psmouse ptmode=1" to force that mode at boot time. note that this does _not_ give the laptop a true tablet device. what these changes basically let you do is select between two different mouse-like touchpads: 1) the current (capacitive) touchpad we all know and lov^H^H^Hhate, and 2) a much wider (resistive) touchpad that behaves very similarly except that you have to press pretty hard with sylus (or maybe a fingernail) to get it to do anything. it isn't jumpy, like the capacitive pad, but it does jump sometimes (on my laptop, at least) if you don't keep full pressure on continously. please let me know what you think. implementing a UI of some sort to select the modes is someone else's department. paul p.s. there are ifdefs in the driver for running the pen tablet as a true tablet, with absolute positioning, but that mode isn't well thought out, and isn't suitable for general use of the laptop. =--------------------- paul fox, p...@laptop.org _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
