Did anyone find resolution to this problem? It just happened to me. No changes in hardware or anything, I just tried to select one of the resolution options available on my display preference menu.
When I picked it, the screen went black (G4 AGP, using a big Sun Microsystems CRT monitor). I know the OS is loaded, because I makes noises at me when I hold down the Esc key.
I reset the PRAM and PMU, so now I get a grey screen, then the "forbidden" symbol, so I know it is capable of output to my monitor.
I've also hooked it up to a newer monitor, and used both types of connections on the graphics card interface, same result.
When I try booting up from the OSX 10.3 or OS 9.2 discs, I get the grey apple screen, then the clock-like "working" thing below it... then it goes black again.
I'm going to try to do a low-level reformat of the hard drive, then try to re-install the OS, but I'm not sure why that would work if resetting the PRAM and PMU wouldn't. I'm freaking out here...
