Hi!

Color management is difficult, and in most cases, leaving it to sRGB is the
safest option - that is to be considered the "default" for most monitors.

See a monitor color profile as a way of adjusting the image, so it looks
closer to the 'real world' colors on your monitor. So the color profile is
a way to adjust to the differences each monitor has. Things are not that
easy though. If you are using a generic color profile for your monitor, you
need to know exactly how your monitor must be adjusted (brightness,
contrast, whitebalance, etc) for the profile to be effective. Otherwise
your image will be 'wrong' anyway.

There are tools to create a custom monitor profile, by measuring and
adjusting your monitor. I don't know the tools for Linux, but for Windows
I've used a Spyder color calibrator.  This enables you to do a custom
profile for your specific monitor, which is useful as long as you don't
change settings on your monitor.

If your "System Display Profile" is (noticably) different than sRGB, your
installation may have choosen a generic monitor profile for you. Whether
you feel it better represent the "real" colors is really up to you. Compare
the images on several different monitors to get an impression of how your
monitors behave in relation to others.

I hope this gives you something to start off with.


Regards,
