color-managementgnome
I've calibrated two displays and like to apply those color profiles system-wide.
This should also include the lightdm user, as the switch to my user's color profile happens while logging into the session (especially visually unpleasant if the greeter uses the same wallpaper as my user).
Is this possible?
I've been researching and the closest I could get to, your answer is to after have one user logged in, log the other user (almost) automatically.
1) Open Gnome Session Properties
gnome-session-properties2) and add this to a start up
gdmflexiserver
I will continue my research and post here if I find something else.
Install dconf-editor if you don't have it, and then go to
org.gnome.settings-daemon.plugins.xsettings
and check "active." One thing I've also noticed when this happens is that the media keys stop working: enable org.gnome.settings-daemon.plugins.media keys. There also might be some more plugins you should enable.

A wishlist bug report has been filed and fixed in Ubuntu 12.04, so you will see a button to set a profile as system-wide default (per device).
Open the Color page of the System Settings (press Super and search for Color),
Select the profile that should be applied system-wide.
Click on the Set for all users button in the bottom left:
After entering your password, the color profile should be default for this device for all users, including
lightdm.Ubuntu 11.10
Before above mentioned bug was resolved you were able to do this too, the function is just rather difficult to discover:
Open the Color page of the System Settings (press Super and search for Color),
Select the device which profile should be applied system-wide,
Hit the Menu key (or "context menu key") and select Set for all users:
After entering your password, the color profile should be default for this device for all users, including
lightdm.
