After some poking around in the gnome-power-manager source, I found that it does send the sleep/wake commands to NM if the key '/apps/gnome-power-manager/general/network_sleep' is set to true. If this is false, the sleep/wake signals won't be sent. When I opened up the GConf config tool, this value was false for me. I'm not able to test it yet, but in about 2 hours I'll be able to check and post back if this works. In the meantime, if someone else is able to verify that the value is false and NM properly rescans after waking up with the value set to true that would be great :) -- Joel Goguen http://jgoguen.net/ The human mind treats a new idea the way the body treats a strange protein -- it rejects it. -- P.
