Is there any way to re-probe the monitor's DDC/EDID while the X server is running? I don't expect the server to change the settings it is _using_ without restarting, but would like to get the list of supported Modelines for a newly-connected monitor -- as would be generated in the course of "Xorg -configure" -- while the server continues to run using its old settings. Of course there would be no need to re-probe anything but the monitor, since all other hardware remains the same. The motivation is to simplify a monitor upgrade from: * Log out of X session (restarts X). * Disable xdm in /etc/ttys (shuts down X). * Xorg -configure. * Merge the Modelines from the "Xorg -configure" output into the existing xorg.conf -- using the text-mode console (or restart X with the old settings just to do this merge). * Re-enable xdm in /etc/ttys (restarts X). * Log in/start new X session. to * Re-probe monitor. * Merge the new Modelines into xorg.conf. * Log out / log in (restarts X session using new settings).
