Since I started paying some attention to the photos I make the display calibration issue recurrently came into question. I tinkered as much as I could with xgamma mostly with bad results. This weekend however I could borrow a Spider 3 device and I played with dispcalGUI and argyll. There is not much I could say because the doc on the respective sites is great so after some wait I managed to get and .icc profile for my laptop (Dell Latitude E6410 with Nvidia card (GT218 [NVS 3100M]). If you have a similar laptop you can use the following commands to get some decent colors:

dispwin -I dellE6410nv.icc

This will create a .config/color.jcnf file and copy the profile to .local/share/color/icc/devices/display/

You can clear the profile with

dispwin -c

Of course you need the argyll package installed.

Just want to say thanks for sharing the icc profile.
