[Bug 59867] Re: Synaptics touchpad ceases functioning after suspend and resume.

[Surak]

Well, suspend to RAM and resuming, causes the problem and when this
happens, hibernating to disk  and resuming solves it.

It seems that this fact has been underestimated before. This might, in
fact lead to the solution. Note that in my case, dmesg says that it just
can't query Synaptics hardware. Well, what happens after a hibernate to
disk and resume? The computer is powered off and the synaptics hardware
is reset!

So, I may be guessing too much, but I'm an Electronics Engineer and
would say that maybe the solution to all of this is to send a reset
command to the synaptics touchpad when resuming from suspend to RAM??
