I'm running FC10 on my toshiba, and pressing the hot-keys gives me 8 levels, so somehow Fedora chooses the toshiba levels instead of the ACPI video levels. I too would view it as a regression if this went down to 3 levels, even if it is working by pure luck today. Unfortunately, Andrey is using a distro or window system that is less lucky?:-) I like Henrique's suggestion of having the drivers register a quality with the backlight sub-system and somehow having the highest quality driver win. In the case of a tie, however, I'd want the ACPI video driver to win:-) cheers, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
