Comment 90 for bug 1303736

As the version you've all had the chance to test now was a bit hacky and more of a proof-of-concept (sidenote: it'd also break xscreensaver), we've meanwhile come up with a revised patch that we want to SRU to 14.04 and include in 14.04.1.

DISCLAIMER
Let me be clear about this patch again: it fixes a bug where you get a black screen in a very specific situation, i.e. when you have "lock on suspend" activated and the lid-close event of your laptop is set to "suspend". In this case, for *some* (it is a race condition) first the login-screen appeared and then a blank/black screen. This patch should fix this issue (and nothing else!). If you had previous or other issues with suspending in general, this patch is *not* going to fix that.

Anyhow, please follow these (same as in #56) instructions and let us know how it goes:

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)

Thanks!
