Unlocking screen from CLI prompts for password

[Stanislaw Waszkiewicz]

I use blueproximity to lock my screen when I am going away from my computer.
It is python script that checks distance to bluetooth device and uses:

gnome-screensaver-command -l

to lock the screen when the bluetooth device is away and

gnome-screensaver-command -d

to unlock it.

Since 14.04 I have been prompted for password when I get back to my computer (it is not gnome keyring password, it is unlock screen password). It worked without password before.

I am aware of the bug causing lock screen asking for password twice and I turned off the lock in Brightness and Lock system settings to fix it. It seems that the problem is unrelated and authors of the new unlock mechanism didn't consider unlocking screen remotely or from command line interface.

The problem with screen lock asking for password twice is already solved and it was caused by the fact that the new Unity lock screen didn't turn off the screen.

The new lock screen is entirely implemented in Unity so your gnome-screensaver commands are useless. I know that gnome-screensaver is still used as a fallback mode in two cases. The first is if you have sreen reader enabled and the second one if you have OSK (On-Screen Keyboard) enabled.

This is the branch that implemented new Unity lock screen:

I wrote that I am aware of the lock password appearing twice. But my problem is quite different. Is there a way to unlock desktop similar to gnome-screensaver-command? Is this functionality lost?
