having trouble with screen resoultion

[beleth]

i recently installed fedora 10 and and was dual boxing with 2 monitors, when i found out about KVM switches. So now i am using my LCD HDTV(26") for both boxes. The res on my windows box is 1360x768. So i'm trying to set that in fedora and i'm running into a little trouble, because i don't have that mode in my list in system>preferences>hardware>screen res.

searching these forums i found out that there is no /etc/x11/xorg.conf pre installed. So i used a method to make /root/xorg.conf.new and tried to 'cp' it to the right location. i am logged in as root, and it says that cp: cannot create a new file, or something to that affect. through further searching i think that means i don't have permission to do that, but shouldn't root have no restrictions??

the exact commands are(and i don't know what they mean lol )

/sbin/telinit 3

log back in as root

X -configure

cp /root/xorg.conf.new /etc/x11/xorg.conf

if anyone can help i'd soo appreciate it, this basically renders my linux box useless at this point

Hi and Welcome !

You can gain root privileges through su - command.

Execute this :
