--- Comment #1 from Jason Tibbitts <ti...@math.uh.edu> ---
I can confirm with a Thinkpad W530. My situation is exactly the same. I'm
running Fedora 29 which has powerdevil 5.14.4 currently. I haven't previously
tried to run Linux on one of these laptops so I have no idea if this worked at
some point in the past.
Supposedly (from a quick chat with Matthew Garrett on IRC) the desktop
environment needs to figure out which output port needs to be adjusted, follow
that to the device (graphics card) and then look for the backlight in
/sys/class/backlight which corresponds to the device.
I have to give this laptop to a user, but I think I have another on hand to
test if there's a patch I can try.
