Blue Display on T61

Blue Display on T61

It looks like T61 comes with 2 different displays, LG and Samsung. The Samsung display shows way too much blue. Here are my settings for a quite neutral color balance - that is, it matches my L90D+ TFT and my old T41, but you lose 40% contrast:

If you run your T61 dualheaded, then you have to use Xinerama and not Twinview! Funny to say, nvidia-settings changes the color balance for all attached devices when running on Twinview but only of the notebooks lcd when on Xinerama.

So here is my xorg.conf for pure Xinerama:
