X won't start

[Ray Percival]

Just installed 2.2 when it boots it looks like xfs and xdm both start up. When 
I type startx I get.
x: exec of /usr/bin/x11/xf86_svfg failed. I used xf86config to build a config 
file this is a Diamond Viper 770 and I used the card definition that came with 
x. Any thoughts? Thanks in advance. Ray
