What software are you using for color management?

Last I checked, colord had been broken for at least six months, and the only mostly functional alternative [0] was some project called Oyranos that's signed with expired GPG keys and distributed from some OpenSuse server.

[0] It applies color profiles just fine, but fails to also color-correct full screen programs.

I use oyranos and kolor-manager (depends on oyranos). For color profile auto-loading you will also need xcalib. These work automatically. I only have to generate and install profiles with dispcalGUI.

Color correction works fine for full screen programs with two exceptions: [1] If you have set hardware accelerated (opengl) color correction then it doesn't work on full screen opengl apps. Normal color correction works there too. [2] Color correction never works on VDPAU. Today's CPUs though can decode anything with minimal effort (so no fans spinning uncontrollably), so no need for VDPAU.
