It's the same for me on a Lenovo Y450 with Intel Mobile 4 graphics, but I can change the brightness with setpci -s 00:02.0 F4.B=FF where FF is a brightest mode and 00:02.0 is from lspci | grep VGA. I found this wokraround here: http://bbs.archlinux.org/viewtopic.php?id=73889 How could I set acpi to execute this command on the keypress? (which is detected by acpi_listen)
