    Unable to mirror desktop using Xubuntu 20.04

    I am attempting to mirror my laptop display (Xubuntu 20.04) with a TV for a large group presentation using an HDMI cable. When I go to display from the menu the mirror option is greyed out so I cannot select it. Xubuntu 20.04 is a fresh install on this laptop. Am I missing something really simple?

    In my experience, KDE is rather better with handling external screens than Gnome.

    That said, try xrandr from the command line to configure it manually. Google for a man page and instructions.

    Thank you. Off to experiment with various configurations one of which will probably work.

    Apparently this is a bug that has existed for a while. There is a work around that can be found on the xfce forum, https://forum.xfce.org/viewtopic.php?id=9808. Post #11 explains the work around.
