Some hopefully helpful tipps for working with ubuntu on a lenovo thinkpad t420s.

• Thinkfan: http://guldener.net/blog/thinkfan_t420s
• Nvidia: Enable it in the bios. (Descrete)
• Nvidia: Fix brightness-bug on nvidia: Add 'Option "RegistryDwords" "EnableBrightnessControl=1"' to the device section in your /etc/X11/xorg.conf
• Dockingstation - Audio: Add at the end of /etc/modprobe.d/alsa-base.conf: options snd-hda-intel index=0 model=thinkpad

superb program to gain control over your thinkpad fan.
