I too have this issue on a new Lenovo T410 with the nVidia 3100 running 10.04 LTS 64bit.

Status in Mactel Support: New Status in “gnome-power-manager” package in Ubuntu: Confirmed Bug description: In GNOME Power Management Settings, one can set "Dim display when idle". When this option is checked, and the user allows for a period of inactivity, the screen will dim. When running on battery, however, after user activity (e.g., input from the keyboard, touchpad, or other input device), the screen is not restored to its original brightness state, but instead remains dimmed. Bug #357107 and this bug may be related, since this may have to do with storage of brightness settings. _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
