Under Natty I had a lovely .icc calibration file for my laptop's screen. It's awful without it.
Under Oneiric, when I go to 'Color' in the settings manager only my webcam is listed in the devices that can be colour managed. So I can't install my .icc profile.
I've installed all the gcm/argyl stuff but that hasn't got me anywhere either.
How can I (re)install my colour profile?
(I now consider this a bug. Report filed on launchpad, please mark it as affecting you if it does)
