Hi Christopher, I have tried ubuntu-12.04.2-desktop-amd64.iso and ubuntu-12.04-desktop-amd64.iso: the brightness applet reacts to the hotkeys but the brigthness of the screen does not change.

I thought it was working before 13.04 but I don't remember whether I tweaked something. Maybe I added acpi_backlight=vendor, shall I tried the same old-releases with acpi_backlight=vendor? Do you need me to attach dmesg report for each?
