by I have a Fahrenheit with a SC15025 RAMDAC on it. In all docs I see that
this card is supposed to have an AT&T 20C490. Everything works fine at 8
bpp but if I switch to 16 bpp, colors are messed up with the AT&T 20C490
and the screen goes weird with the SC15025 in config.
The only thing that is working is 15 bpp with the AT&T 20C490 (or 16
bpp and Weigth 555), but programs like XV doesn't support 15 bpp :-(
Anyone has the same problem? Any solutions?
Here is my XF86Config:
