Joerg, I'm sorry but Kiko is completely right. You can only send commands to pbbuttonsd inside the scripts yet but you can't query any values. Sorry.

pbbuttonsd: call pbbcmd in power scripts
Hi, I want to increase or decrease the backlight level upon plug in and unplug the power supply unit. I achieve this with a script in /etc/power/event.d/. But it seams the script hangs in the call of pbbcmd. Is this possible? If I enable the call I get a message INFO: Script '/etc/power/pmcs-pbbuttonsd resume ac ram' lauched but killed after 6 seconds. I tracked it down to the call of pbbcmd. So what might happen there? Bye, Jörg. -- Der Pessimist ist jemand, der vorzeitig die Wahrheit erzählt.

The script will terminate in time and pbbuttonsd process the formerly sent message. Best Regards Matthias -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
