Assuming that this xorg.conf option works properly Option "AccelerationScheme" "none"
I don't think it's an acceleration bug. I grabbed the debugging symbols package and attached to Xorg, and I was seeing the pDev->last.valuators array getting zeroed out in GetPointerEvents, (getevents.c) somewhere around this block of code: events = updateFromMaster(events, pDev, &num_events); if (flags & POINTER_ABSOLUTE) { if (flags & POINTER_SCREEN) /* valuators are in screen coords */ { valuators[0] = rescaleValuatorAxis(valuators[0], NULL, pDev->valuator->axes + 0, scr->width); valuators[1] = rescaleValuatorAxis(valuators[1], NULL, pDev->valuator->axes + 1, scr->height); } moveAbsolute(pDev, &x, &y, first_valuator, num_valuators, valuators); } else { if (flags & POINTER_ACCELERATE) accelPointer(pDev, first_valuator, num_valuators, valuators, ms); moveRelative(pDev, &x, &y, first_valuator, num_valuators, valuators); } That causes the code to add the deltas to 0,0 to get the next absolute position. It's hard to pinpoint exactly where this is happening, because of the code optimization, but the "updateFromMaster" call now seems like the next place to look. -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
