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? It's a classic deadlock situation. Pbbuttonsd started the script which started pbbcmd. pbbcmd sent a message to pbbuttonsd and waited for the result, which won't come because pbbuttonsd waits for the script to terminate. But there is a solution :-) Call pbbcmd with option '-i' and it will immedately return without waiting for a receipt or an error code. 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?
