No, it doesn't work neither on 3.0 nor on 3.1. Interestingly the original patch that definitely did work on 3.0 and 3.1. I'm not quite sure what is the reason for this. I've basically compiled every kernel version from 3.0 to 3.3 :(. > it is actually. What did you have in the sony-laptop sysfs directories > when booting with acpi_backlight=3Dvendor? Unfortunately I don't know and can't reproduce a working solution here :(. Any clue why this could be?
