Binary package hint: acpi-support
Steps to reproduce:
1. Buy a Dell XPS M1330 laptop and install Ubuntu 8.10.
2. Plug it into AC, turn on machine and press F2 to enter BIOS.
3. In BIOS make sure AC brightness is configured to max value (8).
4. Boot into Ubuntu, and use Fn-DownArrow to decrease brightness.
5. Restart and enter the BIOS again. Check the value for AC brightness.
Expected results: AC brightness is back at 8.
Actual results: AC brightness is set at a lower level in BIOS.
Although the actual behavior is maybe the desired behavior in some uses,
it causes problems for dual-boot systems. Windows Vista appears to
handle brightness differently: on this machine, the value set in the
BIOS is interpreted as a maximum in Vista, and the brightness hot-keys
control the brightness within that smaller range. (So if AC brightness
is set to 3 in the BIOS, then the hot-keys in Vista will cause the
actual brightness to vary only in the range 0-3.)
