hi i need to edit my xf86config file (by the way this is REDHAT 9 i am using) as my resolution has gone a bit wrong and i can't see anything on the screen as the res is too large (see an earlier post in software) i have been told to use vim. (or Vi or whatever its called) so i tried by typing:
vim etc/X11/xf86config
this loads vim, but the edit window is empty
can someone please tell me (in complete idiot language):
how to load xf86config in Vim
how to edit it
how to save it
how to get out of Vim to reboot
thankyou eternally if you can help
