** Description changed: The LED-Illuminated LCD brightness cannot be changed neither 1) using hot keys, Fn+Up and Fn+Down (both are detected by acpi_listen, but dbus does not detect Fn+Up -- if needed I file another bug on this issue only) or 2) echo 1 > /sys/class/backlight/acpi_video0/brightness (no changes on display) or 3) using /proc/acpi/video ... (which do not exist). The only way is calling 'nvidia-settings -a brightness=xxx'. I don't know if this hardware accepts real brightness changes, if not (so it is not a bug in linux), I would be glad if you can help me tweak acpi and dbus to call nvidia-settings (nvclock does not work). $ acpi_listen video LCD 00000086 00000000 [Fn+Up] video LCD 00000087 00000000 [Fn+Down] $ dbus-monitor interface="org.gnome.PowerManager.Backlight" signal sender=org.freedesktop.DBus -> dest=:1.143 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired string ":1.143" [Fn+Up does nothing, but Fn+Down:] signal sender=:1.16 -> dest=(null destination) serial=62 path=/org/gnome/PowerManager/Backlight; interface=org.gnome.PowerManager.Backlight; member=BrightnessChanged uint32 87 Thank you in advance.
