[SOLVED] Ubuntu XRDP authentication is required to create a color-managed device

Ubuntu 18.04 xrdp RDP Error

If you are like me, trying to connect to your Ubuntu desktop remotely using a Windows RDP client and are stuck with the error message:

authentication is required to create a color managed device

Simple Solution

Click the CANCEL button, and it will take you to the desktop!

Note, this is a temporary solution, you will be stopped by this pop-up message every time you reconnect.

Permanent Solution

Edit the file, /usr/share/polkit-1/actions/org.freedesktop.color.policy

vi /usr/share/polkit-1/actions/org.freedesktop.color.policy

Go to the defaults section and modify <allow_inactive>no</allow_inactive> to <allow_inactive>yes</allow_inactive>

<defaults>
    <allow_any>auth_admin</allow_any>
    <allow_inactive>yes</allow_inactive>
    <allow_active>yes</allow_active>
</defaults>
