I have Leopard installed on my Dimension 4600 with an ATI Radeon 9550. I installed the drivers (Callisto 003) and restarted and went into System Preferences -> Display. Prior to installing the drivers I only had one option and so I now saw an entire list of options.
I clicked on one and the monitor went black with a message "cannot display this video mode"
So is there any way to reset my monitor setting back to 1024x768? I have tried typing in the following on boot but it did not work (maybe im doing it wrong)
"Graphics Mode" = "1024x768x32"
Thanks in advance I appreciate any help
