That solution destroys startup/shutdown Ubuntu welcome screen though, so I'd love to try your acpi_osi="Linux" solution, if only I could find the menu.lst file.
Also, in your previous post you emphasized that "Linux" should be inside double-quotes, but now you omitted them. How come?
Pioterek, thanks a lot for your time. Unfortunately, the file /boot/grub/menu.lst doesn't seem to exist on my Ubuntu 10.04 (Lucid Lynx).
However, I did manage to enable brightness controll by editing /etc/default/grub as described in: /bugs.launchpad .net/ubuntu/ +source/ acpid/+ bug/392948/ comments/ 29 /bugs.launchpad .net/ubuntu/ +source/ acpid/+ bug/392948/ comments/ 30

Sorry for taking your time.
