I have a strange problem. I installed an OES Linux Box on an HP standard monitor 1024x768. Then I took the box to another office where they have an Acer AL718 Flat screen LCD Monitor. I plugged it in, switched on and it worked fine. The office has been closed over Christmas, and this morning I switched on the monitor and it was black. The machine was still running, but black screen that wouldn't wake up.

Switched off the box and restarted, - Black screen - Booted in Text Mode, invoked Sax2 and get a message telling me to reinstall the monitor, but no matter what I do, it won't work - I get all the graphics displays correct on text, but as soon as I restart the box - Black Screen. Any ideas?
