Yes, I've seen this on XFCE 4.11 (in Ubuntu), although I haen't seen
it in XFCE 4.10 (in Debian). In 4.11, when xfce gets out of sync,
xrandr --auto will allow me to enable the display, even when
xfce4-display-settings does not.
However, on my T540p with the monitors connected via the dock, which
is the problem I was describing here, xrandr --auto does *not* fix
things up. So I think it's a different problem, since I can see this
problem even if I don't use xfce4-display-settings, and just use
xrandr directly.
