Comment 56 for bug 1303736

If anyone is able to test the fixed packages for this the instructions are :-

1. Add the Xubuntu Developers PPA to get the new packages: sudo add-apt-repository ppa:xubuntu-dev/ppa

2. Update package information and update the two crucial packages:

sudo apt-get update && sudo apt-get install xfce4-power-manager light-locker-settings

xfce4-power-manager-data will get upgraded at the same time

3. Open light-locker-settings and make sure "Lock on suspend" is enabled (if it already is, disable and then re-enable it, then hit "Apply").

4. Restart your machine.

5. Close your laptop's lid.

6. You should be presented with the unlock screen upon opening the lid, login and you should see your desktop (after some VT-switching flickering)

To remove the upgrades and return your machine to it's state prior to testing

sudo ppa-purge ppa:xubuntu-dev/ppa
