I have a monitor with oversaturated red (HP LP2475w). I am able to apply ICC profile to various apps like GIMP and Firefox and Gnome.

But I'd like to apply it to everything - because e.g. Flash animations in Firefox are rendered by Flash and don't use ICC.

So, can I apply it to whole X?

You can try xcalib

/usr/bin/xcalib -d :0 /path/to/your/icc/file.icc

http://xcalib.sourceforge.net/ - the app websit. But try to search it in your distribution package manager.

Works, thanks, however, I can't change for a single screen, only for whole display. -s 1 says "X Error of failed request: BadValue (integer parameter out of range for operation)". I have nVidia TwinView enabled, so that might be the reason. Ideas? – Ondra Žižka Apr 16 '11 at 0:13
    
Try something like -d :0.1, but really I have no real ideas... – Evengard Apr 16 '11 at 10:38

With Oyranos and CompICC the whole desktop is corrcted in hardware. Look at http://compicc.sf.net Make sure all applications use the system profile.
