From a3d4930699f6544794befe00e0ceb91d55b8b65f Mon Sep 17 00:00:00 2001 From: Florian Schäfer Date: Sun, 8 Jun 2008 18:53:31 +0200 Subject: Add synaptics-0.14.6-poll-delay.patch from SuSE syndaemon is a program that monitors keyboard activity and disables the touchpad when the keyboard is being used. Syndaemon is commonly used on laptop computers. Monitored with PowerTOP (http://www.lesswatts.org/projects/powertop/), syndaemon causing 45 wakeups a second because of a hardcoded 20 ms timer. This behavior significantly reduce battery life. This patch introduces a commandline switch to modify the poll delay. Running e.g. "synadmon -m 500" uses a 500 ms timer instead of the hardcoded 20 ms one, makes syndaemon disappear from PowerTOP, while still doing a accurate job.
