(first line; both conditions are true). The finger motion on the pad, while doing the tap, is large/moved enough for it to also be consideret a toss. A toss stops when you touch the pad again; so you are tossing while pressing the stick and pushing the buttons. To stop this behaviour: A) Disable toss, dooh. See the question below. B) Set a higher constant for min_toss_dist or min_toss_time. C) Apply following patch, which prevent a tap and a toss to be activated at the same time. diff -uR gpm-1.20.1 gpm_my --- gpm-1.20.1/src/synaptics.c +++ gpm_my/src/synaptics.c @@ -1933,6 +1933,7 @@ /* No finger on the pad */ /* Start the tossing action if enabled */ if (tossing_enabled && was_fingers == 1 && + !time_to_forget_tap && !was_tossing && !is_scrolling && (packet_num > min_toss_packets) && > btw, gpm doesn't compile when you define DEBUG in synaptics.c unless you > also comment out L1156: It didnt matter. > > > i tried adding [tossing_enabled] FALSE. with that, taps don't work at > > > all (i only had them set up to left click or left click + drag) and > > > neither do the touchpad buttons. the random motion problems are gone, > > > but i suppose that's because taps do nothing now. So why does disabling tossing stop taps/buttons? (It should not influence it at all). Could you send some output where you press a button and do a tap. > > set them up to left click + drag ??

Ok. I understand now: You have not coded a new "left-click-drag" action, but uses the "left-click" action. (I read it as drag-lock) Peter
