[ubuntu] Minor weird Unity behavior (3): Lock screen works randomly when idling

view full story

http://ubuntuforums.org – Hi I'm using 11.10 with Unity. I have observed that lock screen does not behave consistently after the machine has been idling for a while and resuming from screen saving. Types of behavior is one of: - From screen saver to login screen (expected, ~50%) - From screen saver to desktop (a few secs, sometimes allowing interaction) then black screen then login screen (not expected, ~30%) - From screen saver to desktop (not expected, ~20%) Doesn't bother me as such, but is not reliable in certain circumstances. thanks f (Hardware)
