Comment 99 for bug 59867

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??
