On Trusty (beta), while trying to diagnose an issue with the wireless not connecting upon resume from standby, I discovered an invalid check in '/usr/lib/pm-utils/power.d/wireless'. The script checks '/sys/class/net/$1/device/enable' to see if the wireless device is enabled, failing to perform any configuration if this sys file does not exist. That happens to be the case for me (intel wireless), which the actual location is '/sys/class/net/$1/device/enabled' (enable -> enabled). Changing the script to use the correct location has not fixed my wireless resume issue, but perhaps it is contributing to wireless issues for others. My wireless power-saving is correctly turned off upon resume now, though (it would get stuck in power-saving mode sometimes). $> lsb_release -rd Description: Ubuntu Trusty Tahr (development branch) Release: 14.04 $> apt-cache policy pm-utils pm-utils: Installed: 1.4.1-13 Candidate: 1.4.1-13 Version table: *** 1.4.1-13 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1299975/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
