once you've enacted setup_350.sh, how do you reverse it's affects?

it didn't seem to work...i need to go back to using my onitor, but now my x server won't start. is there an automated way to undo the setup command?

final lines of the xfree86 log

(EE) open /dev/fb0: No such device
(EE) Screen 0 deleted because of no matching config section.
(EE) Device(s) detected, but none match those in the config file.

Fatal server error:
no screens found
