let me weigh in on this. about 2 years ago, i had need to turn off the TAP ON PAD ===>>>>> clicking a button The fix was to take the touchpad into absolute mode and that way we had access to the tap bits in the mouse packets. Problem was that when power went away (like for hibernation) the system would come back with the pad in relative mode and tyap enabled again. The fix for this was to use a hook in the APM daemon to restart the modified GPM hope this is of some use. > From: Peter Berg Larsen <pebl@xxxxxxxxxx> > To: gpm@xxxxxxxxxxxxxx > Subject: Re: Touchpads > Date: Sun, 24 Mar 2002 02:08:48 +0100 (MET) > > On Fri, 22 Mar 2002, Nico Schottelius wrote: > > > > > The problem is, we cannot think the device is initialized and reseted > > > > fine by programs before. > > > > So I think the better solution is a reset in the initialization > > > First of all a reboot will reset the touchpad to relative mode (ps2) so > > > rebooting from or to windows will not change matter (if I read STIG page > > > 17 correct 1)). > > I never read STIG.
