Does the screen fail to load or is it just the messages?

Does it shutdown though?

The button calls this:
    def SHUT_SYSTEM_DOWN_PROMPT(self):
        import subprocess
        try:
            try:
                subprocess.call('gnome-session-quit --power-off', shell=True)
            except:
                try:
                    subprocess.call('xfce4-session-logout', shell=True)
                except:
                    try:
                        subprocess.call('systemctl poweroff', shell=True)
                    except:
                        raise
        except Exception as e:
            LOG.warning("Couldn't shut system down: {}".format(e))

Linuxcnc expects a Xorg desktop. The distribution images use XFCE for this reason
Gnome by default uses wayland which is very problematic for Linuxcnc. You can change to use Xorg from the Gnome logon screen

Some distros also have XWayland that can be choosen at login, most XOrg stuff should work OK with it and so do Wayland only apps.

A fix for shutdown (I think) has been pushed to 2.9/master today.
One of the QtPlasmac (Greg) developers came up with.

Thanks for mentioning the problem.
