Gnome Shell 3.10.4 on Ubuntu 14.04.1 Does Not Lock Screen After Resume From Suspend or Hibernate

[Majal]

I recently installed a fresh 14.04.1 system (with a separate partition for the /home directory from 12.04). As expected bugs and tweaks here and there are present but with the help of forums, I was able to solve them one by one. There are just a few now remaining but this one looks critical and there seems to be no answer from the forums: gnome-shell does not lock (no passwords asked) after resuming from either suspend or hibernate. I checked all the settings, gconf, dconf, Settings > Privacy > Lock Screen on Suspend.

I suspend / hibernate, then resume / thaw, and the desktop directly goes to my user, no locking has happened.

WORKAROUND:

After the first login, I lock the screen, eg Ctrl + Alt + L. Lock screen works. Then I suspend / hibernate, then resume / thaw: Lock screen works again. So in order for the Lock to work, I had to do an initial Ctrl + Alt + L.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 49579, so it is being marked as such.

This is a fundamental bug in the design of X11 and cannot be easily fixed within X11.

You should manually lock your screen if a locked session is important to you.

Please continue to report any other bugs you may find.

Wow, I checked that bug and it's a whole lot of mess. Hmmm, the future seems to be moving further away from X11. Anyways, thanks Seth for taking the time to reply on this. Have a great life ahead!
