Description BjoernC 2013-10-19 21:05:13 UTC 
During some tests, i have found out, that the brightness control of the integrated monitor is no longer available (Notebook: Lenovo T430-D17, optimus disabled, nvidia-card active, uefi enabled). If i go back to the Kernel version 3.11.0-4, the brightness control works fine. However, may be this helps to find a proper solution.

I have tested the kernel version 3.11.6 and the issue does not exist anymore in this version. Maybe this issue has been fixed in previous versions.
