It could be...in fact the behaviour is similar...but I also think is related to Unity, in fact since I switched to Gnome Shell I don't have this problem anymore...

It is the same behaviour than in this old bug #199522. After additional testing I've noticed that the problem is independent from "dim on idle" To manage notifications about this bug go to: https://bugs.launchpad.net/unity-greeter/+bug/844241/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
