Re: How to modify xorg.conf from command line in rescue console (F7)

Most likely not installed. For reference, you can install it with

 > yum install joe

run as root, once you have networking going. However, I guess you can do what 
you want with nano ...

I suggest you post the full xorg.conf file you now have on your running F7 
system here...

you need to learn a little about your /boot partition. This is where your 
kernels live, and also where the configuration for grub lives, the boot 

The file


defines the options presented to you at the grub menu, and here you can add 
any custom kernel options you like. Look for lines like

 kernel /vmlinuz- ro root=LABEL=/ quiet

Its on this line you can append any options you want. I.e. to add the ones you 
used by the installer, change to something like

 kernel /vmlinuz- ro root=LABEL=/ quiet vesa i8048.noloop 
psmouse.proto=imps clock=pit

its as easy as that. If you have more than one kernel option listed in there, 
just add the options to them all. Also note, whenever new kernels are 
installed your options are automatically copied to the new ones, so no need 
to do it by hand again.
