I use Fedora 20 with 3.13.10-200.fc20.x86_64 kernel and I got these rows in dmesg:
[ 17.687283] thinkpad_acpi: Unsupported brightness interface, please contact ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx
[ 17.687380] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver
My box is a Lenovo ThinkPad T530. If you need more info just ask.
Kind regards,
Balint
