Hi,
the following appears during boot on a fresh Ubuntu 15.10 installation
on a new ThinkPad P50. Maybe it can help you, however the function keys
(especial brightness-keys) are fully working.

Hi!
I have ThinkPad E545 laptop with Ubuntu 14.04 installed. When booted it
reports the "thinkpad_acpi: Unsupported brightness interface, please
contact ibm-acpi-devel@lists.sourceforge.net" error.
Once booted, the brightness is at maximum, but I can adjust it with
brightness soft keys (F7/F8).
Sounds good. Thank you very much for the information.
Best regards,
Greg

You can just ignore this, it is likely going to be fixed in Linux 4.1,

I'm running Ubuntu 14.04 LTS on a Lenovo X140e (AMD/ATI: Kabini Radeon
