Part of your comment is missing... What else did you instrument?
I'm going to CC the maintainers. Could you first upload your:
1) .config
2) an acpidump file. (You may need to apt-get install acpidump)
3) the output from "sudo lspci -vv"
There are three ways to set the backlight setting on the computer. The
platform specific way (dell-laptop), using ACPI, and through the GPU. I
thought the only way to access those controls was through sysfs though.
