Comment 46 for bug 559163

Hi could someone post a detailed explanation on how to edit the grub.cfg file. It said read only and I dont know where to put the "nomodeset" since i dont have a line looking like the Benny Hult has: "linux /vmlinuz26 root=/dev/disk/by-uuid/626f55f1-1946-46e4-9b74-47d00bb9e119 ro quiet splash nomodeset"
