Sorry for the delay... I've an Intel graphic card 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) After some other investigation I will try to summarise the problem, because I've seen different behaviour with dim enabled/disabled
With dim enabled: 1)leave pc idle 2)when the monitor goes black wait a few minutes 3)move the mouse/keyboard but the screen remains black, even if you change screen brightness using the special key (Fn-F6) With dim disabled: 1)leave pc idle 2)when the monitor goes black wait a few minutes 3)move the mouse/keyboard but the screen remains black 4)if you change increase screen brightness using the special key (Fn-F6) the back light turn on and I can use the pc Note: if I leave the pc idle for about an hour with even with dim disabled I cannot any more restore the back light Feel free to ask me clarification if my description is not very clear... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/844241 Title: Dim on idle does not brighten with activity Status in “gnome-power-manager” package in Ubuntu: Confirmed Bug description: I've upgraded my laptop from natty to oneiric and I've noticed that when I leave the pc idle (or I manually lock the screen) the back-light is not restored when I move the mouse or press a key, but I must turn it on and increase it using the keyboard button. Is the same behaviour described in this old bug #199522. Naturally if I uncheck the option "dim screen to save power" the issue doesn't occur.
