I'm not a Ubuntu developer. I just bumped into the disabled calibrate button and came here via Google. I later realized that it was due to a calibration device not being connected. I was expecting some manual calibration instead and incorrectly confirmed this bug.

Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: I have an Asus Zenbook NX500. The color profile is wrong as red is very, very saturated. To fix this I should be able to use Systems Settings -> Color -> Calibrate to adjust the settings but this is greyed-out/disabled. I've tried running "sudo unity-control-center --overview" to see if it was a permissions issues with my account but the Calibrate button remains greyed out. Since I can't calibrate my screen I consider this a bug. d@Epimetheus:~$ lsb_release -rd Description: Ubuntu 15.04 Release: 15.04 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: unity-settings-daemon 15.04.1+15.04.20150408-0ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-16.16-generic 3.19.3 Uname: Linux 3.19.0-16-generic x86_64 NonfreeKernelModules: wl nvidia ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 CurrentDesktop: Unity Date: Tue May 5 18:41:30 2015 ExecutablePath: /usr/lib/unity-settings-daemon/unity-settings-daemon InstallationDate: Installed on 2015-04-23 (12 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Beta amd64 (20150326) ProcEnviron: PATH=(custom, no user) SHELL=/bin/bash LANG=en_US.UTF-8 LANGUAGE=en_US XDG_RUNTIME_DIR=<set> SourcePackage: unity-settings-daemon UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1452096/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
