Thanks for the suggestion. Unfortunately it doesn’t seem to have had any effect. L Regards, Glenn Alexander Technical Officer Digital Media Centre From: Another Sillyname [mailto:anothersname@googlemail.com] Hi You probably need a variation on something like this.... Section "Screen" I can't remember which one monitors power events of the top of my head and am just heading out to a meeting...... It should give you a starting point though....I run numerous machines headless but sharing a monitor when required using the above xorg.conf settings.

The signage monitors are internally configured to shut themselves down overnight and restart themselves each weekday morning. This plays merry havoc with the content as X11 and/or the window manager (kWin) tries to shuffle things around to fit on remaining monitors. End result is the control monitor (which doesn’t shut down) ends up with everything on it the next day. I am having trouble working out how to disable the automatic monitor detection so that X11 just carries on as if the monitors are still there while they are shut down for the night/weekend. Basically I want to completely ignore all monitor power events. Hunting around the ‘net has given me tantalising hints that DPMS or udev may be involved but since everyone else in the world seems to want the exact opposite of what I want* (ie, to have automatic P&P) I am having little joy finding a solution L *…well… plenty of Windows7 users complaining about not being able to change channels on a HDTV being used as a secondary monitor without scrambling their desktops, while MS ignores them, but that is even less help.
