Bluetooth Can't Connect to Devices After Suspend

[Cerin]

Binary package hint: bluez

I'm running Ubuntu 10.04 on a Macbook 5.5. I was using the Macbook's builtin Bluetooth, which working fine, even with suspend. However, this recently got fried, so I was forced to start using a Targus USB Bluetooth adapter.

The adapter works fine after a fresh reboot. However, Bluetooth becomes unusable after suspend. Before suspend, I can use the "Bluetooth Preferences" dialog to detect and pair to bluetooth devices, but after suspend, it shows the devices I had previously paired with, but doesn't detect them or provide a way to reconnect. The only solution I've found is to remove the pairing, set my device back into pairing mode, and repair, which is very frustrating.

Note, this appears to similar to the problem reported in https://bugs.launchpad.net/ubuntu/+source/gnome-bluetooth/+bug/591298

Based on the comments in that ticket, there appears to be a bug in bluetooth-applet that causes it to break after suspend.

The workaround is to add the following script to /etc/pm/sleep.d

#!/bin/bash
case "$1" in
    resume|thaw)
        killall bluetooth-applet
        nohup bluetooth-applet &
        ;;
esac

which kills and re-runs bluetooth-applet.
