Nvidia Gforce 6600 - Mode not supported - G5 Quad

[Mages Simon]

Hi there,

i try get X up and running on my G5 Quad PowerMac.

But whatever i tried, i got the "Mode not supported" error from my
Display.

The Display is a "Belinea 1705 S1", it is capable of 1280x1024 at 60.

I don't know what i could try next.

I already tried fbdev and vesa as alternatives to the nv driver but
without Success.

I don't need acceleration and such things, i only need a working X to
run my fluxbox in. :)

Any ideas what im doing wrong?
