====== PolKit colord error ======

===== Summary =====

After the upgrade to Devuan chimaera (Debian Bullseye), I received a message 
**Authentication Required to Create Managed Color Device**
when trying to log in remotely (via VNC).

A little research and I found the excellent articles at https://c-nergy.be (see links at bottom), where they (//Griffon//) walks through how they found the problem, researched the hell out of it, and found a long term solution. Here is a summary, but I recommend you read the two posts at the bottom.

**Note**: Their article was written for Ubuntu, but works just fine for Devuan (and, I assume, Debian)

===== Quick Instructions =====

<code bash>edit /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla</code>
<code conf 45-allow-colord.pkla>
[Allow Colord all Users]
Identity=unix-user:*
Action=org.freedesktop.color-manager.create-device;org.freedesktop.color-manager.create-profile;org.freedesktop.color-manager.delete-device;org.freedesktop.color-manager.delete-profile;org.freedesktop.color-manager.modify-device;org.freedesktop.color-manager.modify-profile
ResultAny=no
ResultInactive=no
ResultActive=yes
</code>

**Note**: the Action line is over 270 characters long. That is correct.
