Description Cosimo Cecchi 2012-05-16 20:44:55 UTC 
To reproduce:
- add a color profile to a display in the Color panel of System Settings
- click on "Set for all users", a polkit dialog will ask for your password and complete succesfully
- log out
- the GDM screen doesn't have color correction (first bug, but not the interesting one)
- log in as your previous user
- there's no color correction on the display

Opening up the Color panel again shows no profiles at all for the display; in .xsession-errors I see this line repeated 4-5 times after login

(gnome-settings-daemon:5678): color-plugin-WARNING **: failed to set xrandr-Lenovo Group Limited gamma tables: failed to generate vcgt

and when I open up the Color panel I see

(gnome-control-center:5979): color-cc-panel-WARNING **: /var/lib/colord/icc/GCM - LENOVO - 7465CTO (2010-08-09).icc is not usable by this user

Removing the file from /var/lib/colord/icc and restarting colord restores things back to normal (i.e. the session profile is applied again and the Color panel shows the list of available profiles for the display).

Hopefully this fixes things (in colord):

Thanks for the quick fix, works fine with git master.
Closing this - I opened bug 676271 and bug 676273 for two other related bugs.
