Hi,

After about 15 minutes without going to the other virtual desktops, they become black (In all activities).
It is like other screens hibernates, but you can not unlock this. 
If you use two desktops, just the other "hibernates". 
But if you let hibernate all the computer, the hibernating windows are not unlocked.
But if you go on the black screen, you can retrieve only the last open virtual desktop with ctrl-F8.

Best regards

Jeanne
