Problemswith XFree4.0

[paca]

        Hi all, 


I've got some problem to start X server.
It's crash with this error message : 

"Fatal server error : 
Could not open default font 'fixed'
"

How can I fix this ?

How should configure the input device for the touchpad ?

I've got a ATI RAGE LT PRO with 8MB Ram
and my laptop is a sager nautilus


Thanks
Pac
