I've used portdowngrade for that purpose. My GF3 is not supported by 97xx as well. The x11/nvidia-driver port has a WITH_LEGACY_GPU_SUPPORT knob that downgrades it all the way to version 7184, which supports many older GPUs. - Bartosz ___

6.2 nvidia x11 driver: weird 16bpp/24bpp colorspace damage

2007-01-14 Thread Dmitry Marakasov
Hi! I've just upgraded to 6.2 and found terrible bugs with nvidia x11 driver. Everything works (i.e. X starts, opengl works, no errors), but all colors are damaged terribly. It feels like graphics card is in 16 bpp mode, but X server thinks that it's in 24/32 bpp mode. Thus, value of blue channel
