Editing xorg.conf?

[wtf]

hello all. i'm new to linux and need some help getting my machine setup. i'm running the ubuntu based Green OS and cant get my video card properly configured. i've already gone through the forums to figure out what i need to do to get my ATI card working but my system wont let me access the xorg.conf file. i can see it using the the GOS file editor but it wont let me save the modifications. when i attempt to edit from a terminal window with su privelages it tells me that /etc/x11/xorg.conf does not exist. i've even tried booting into recovery mode and using the root instead of the sudo command. nothing i've tried will let me open the file. Can anyone help me with this? any input would be greatly apprciated. thank you

after it displays that last message gedit opens up a blank document. if i open up the file system folder i can navigate to x11 and view the xorg.conf file but i cant write to it. i tried to copy it and paste it (with changes) to the blank file created by gedit but when i try to save with as a root user it wont let me have access to the x11 folder.

What am i doing wrong??

Hi and Welcome !

Its a Capital X in X11.

If you are using Terminal to edit file then use nano text editor instead of Gedit.

nano /etc/X11/xorg.conf

Or
Press Alt+F2 and type this

gksu gedit /etc/X11/xorg.conf

It will open xorg.conf file in Gedit with root privileges.

Hi and welcome,

Like he said it is a capital X. try executing:

aticonfig --initial -f

This will create a new xorg.conf.

Then restart X:

/etc/init.d/gdm restart
