see "man xset" as a reference, but my (very basic) understanding is that the 7/4 (or 7/6) is a fractional multiplier, which causes the mouse to move faster by a factor of 1.75 (or 1.17). so other things being equal, using 7/6 will cause a slower mouse curser than 7/4. the second number is the number of pixels the mouse must move before that multiplier is applied. so "xset 7/4 10" will start multiplying mouse movements by 1.75, but only after an initial movement of at least 10 pixels. that's not the whole story, though, because if it were, you'd expect "7/4 1" and "7/4 0" to be roughly equivalent -- and they're most definitely not. "7/4 0" (the current values) cause a far higher mouse speed than "7/4 1" or "7/6 0". so there's more going on that i don't understand. note that a '0' threshold has become "special" in the most recent versions of the X server, and implies a non-linear multiplication that makes the old threshold-based configuration sort of obsolete. but the XO-1 doesn't have that feature, and it's not completely clear (to me) what it's doing with the 0 value threshold that we're setting. paul =--------------------- paul fox, [email protected] _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
