Hi, back in June I posted a patch for syndaemon. Syndaemon is causing 45 wakeups a second because of a hardcoded 20 ms timer: Ref: http://www.bughost.org/pipermail/power/2007-June/000602.html
Here is a new patch that introduces a commandline switch to modify the poll delay for nearly disappearing from powertop, causing only 3 wakeups a second while still working accurate. I also maintain a patched version in openSUSE 10.3 repository: http://download.opensuse.org/repositories/home:/FunkyM/openSUSE_10.3/i586/x11-input-synaptics-0.14.6-109.1.i586.rpm -- Best regards, Florian Schäfer synaptics-0.14.6-poll-delay.patch: =================================================================== --- ./syndaemon.c 2006-04-16 21:31:43.000000000 +0200 +++ ./syndaemon.c 2008-01-21 13:40:02.000000000 +0200 @@ -43,9 +43,11 @@ static void usage() { - fprintf(stderr, "Usage: syndaemon [-i idle-time] [-d] [-t] [-k]\n"); + fprintf(stderr, "Usage: syndaemon [-i idle-time] [-m poll-delay] [-d] [-t] [-k]\n"); fprintf(stderr, " -i How many seconds to wait after the last key press before\n"); fprintf(stderr, " enabling the touchpad.
