After changes in my xorg.conf, i can not restart X anymore. So on Grub i choose , limited vodeo mode, then "root prompt". Though it seems to be a read only access, so i can not replace my current xorg.conf by my saved one.
I tried to use chmod, but without success, i get a message :
"Changing permissions for xorg.conf : Read access Only" even though i entered "chmod 666 xorg.conf"
How can i modify or delete my current xorg.conf in such a scenario ?
THanks for the help !
