Dell Precision T1700 default xorg.conf file needed

[Yasha Karant]

The ElRepo Nvidia driver seems to have erased (not backed up) the 
default X11 xorg.conf file on a Dell Precision T1700 with an addon Nvidia
card.  With the Nvidia card in place, the system will not boot (blocked 
by the Dell bios); the card has been physically removed. The system boots
to a standard terminal login prompt and will allow login; however, no 
GUI login, and both startx and xinit fail.  SL 7.1 .  Does anyone have a 
stock xorg.conf file or URL for one that will work on this platform and 
environment (including a pointing device, etc.)?  Does anyone recall the 
command that will "automagically" rebuild a working xorg.conf file?  I 
can play with this, but it is easier to get this operational.
