No screen input after SL Graphicsupdate 1.0

[joelmeijering]

In order to get my Club3D HD5770 working in SL, I gotta get the SL Graphics Update 1.0 and 10.6.4 first right?

 

10.6.4 works, but when I install the graphics update I get no video signal (black screen).

 

Does anyone know how to get the graphics update or how to get 5770 working without the graphics update?

 

 

 

Thanks in advance,
