Comment 114 for bug 286424

For a Single Head System, you are all right that the xorg.conf file can and will work correctly if created running in Sudo or gksudo this is true for the 180. 185. and the new 190. if you are using Ubuntu 64-Bit 9.04 and 9.10 versions.

But this only works for a single-head systems. Once you try to configure a dual-head card or trying to activate two screens it will not save your changes at all. Can someone please try running Ubuntu 9.10 latest version, use a Ge-force 9500gt card and try to configure up 2 screens one for crt and the other s-video for TV out and you will see what I mean. You cant even configure a Twinview. The Geforce 9500gt card has 2 DVI and 1 S-video tv-out.
How do you configure a dual head system. I cant even get a clone to work, where one screen clones the other.
