You have been subscribed to a public bug: Mirrored displays is not accessible (grayed out) when trying to activate this feature for multi-monitor support. I am not sure which specific package to nominate for this bug, but it seems to only be happening on systems with XFCE4 installed and running (Including Xubuntu, Mint, and Debian).
It maybe an error with the package xfce4-display-settings, but I am not sure.
