Package: gnome-color-manager Version: 3.18.0-1 Severity: grave Since a recent upgrade (Debian/Sid) the primary screen is not listed in the color manager. I have experienced this issue on two computers. Also the secondary screen when attached is properly listed in the color managed devices.
With this bug it is not possible to unset or change the profile for the primary screen. If this can helps: $ gcm-inspect -d (gcm-inspect:5147): Gcm-WARNING **: failed to get XServer profile data: failed to get property (gcm-inspect:5147): Gcm-WARNING **: failed to get XServer protocol version: failed to get property Regards, -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://v2p.fr.eu.org http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B
