No CGX screen modes listed

Hi,

I'm trying to set up CybergraphX on my A1200, which has a Voodoo 3 graphics card in a GREX. I cloned the hard disk from another A1200 that only has AGA, installed CGX, and now the boot-up screen is displayed ("Light my fire"), but there aren't any CGX modes listed in the display prefs (I'm using the Workbench through composite output). The only monitor driver in DEVS:Monitors is voodoo3.

I did a test installation of OS3.9 from scratch on another HD, and CGX worked fine. The problem only occurs with my cloned HD. I've tried to disable any graphics.library patches etc., but maybe there's something I've forgotten about. Does anyone know what might cause this problem?

Thanks a lot, that saved me a lot of time experimenting :-) My problem now is that the V4.3 update needs the CGX CD, which I don't have. Would it have been provided originally with the G-REX board (which I bought second-hand) or does it need to be bought separately?

Thanks all. I patched the CGX library and it's working now.
