As bgcommon notes, the bug is easily triggered. Set your brightness to a certain level with the Brightness Applet. Alter the brightness with the [Fn + Up] or [Fn + Down] key. Close/reopen the laptop lid and the level will revert to that which had originally been set in the Brightness Applet.
As you requested, here are the results of the commands. The commands were executed after setting the brightness with the Brightness Applet but before using the [Fn + *] key: gconftool -a /apps/gnome-power-manager/backlight -------------------- idle_dim_battery = true idle_brightness = 30 dpms_method_battery = default dpms_method_ac = default idle_dim_time = 30 brightness_battery = 70 enable = true idle_dim_ac = false brightness_ac = 81 battery_reduce = true gnome-power-bugreport.sh -------------------- Distro version: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu 8.04" Kernel version: 2.6.24-19-generic g-p-m version: 2.22.1 HAL version: 0.5.11rc2 System manufacturer: missing System version: missing System product: missing AC adapter present: yes Battery present: yes Laptop panel present: yes CPU scaling present: yes Battery Information: battery.charge_level.current = 50116 (0xc3c4) (int) battery.charge_level.design = 53280 (0xd020) (int) battery.charge_level.last_full = 50116 (0xc3c4) (int) battery.charge_level.percentage = 100 (0x64) (int) battery.charge_level.rate = 11 (0xb) (int) battery.is_rechargeable = true (bool) battery.model = ' DELLUD2657' (string) battery.present = true (bool) battery.rechargeable.is_charging = false (bool) battery.rechargeable.is_discharging = false (bool) battery.reporting.current = 4800 (0x12c0) (int) battery.reporting.design = 4800 (0x12c0) (int) battery.reporting.last_full = 4515 (0x11a3) (int) battery.reporting.rate = 1 (0x1) (int) battery.reporting.technology = 'Li-ion' (string) battery.reporting.unit = 'mAh' (string) battery.technology = 'lithium-ion' (string) battery.type = 'primary' (string) battery.vendor = 'SMP' (string) battery.voltage.current = 12424 (0x3088) (int) battery.voltage.design = 11100 (0x2b5c) (int) battery.voltage.unit = 'mV' (string) GNOME Power Manager Process Information: john 7017 0.0 1.1 247184 11636 ?
