Sreen Resolution not sticking!

[s_spiff]

I'm on Hardy Haron x64. Amd 3500+ on a Gigabyte iDNA series motherboard, having a NVidia 6100 graphic card onboard. I installed the nvidia drivers using EnvyNG ( available in the repositories ), automatic mode.
In case of Gutsy, I had an option ( System > Preferences > Screen Resolution ) of upto 1280x1024 with a refresh rate of 96 Hz.
Since I've upgraded to Hardy, the max resolution I'm offered is 1024x786. I bypass this by using System > Administration > Nvidia Server Settings, where I'm able to set a 1280x1024 resolution. But on a reboot, this doesn't seem to stick. It reverts back to 1024x786.

I'm attaching my xorg.conf file. Can someone let me know how to make the settings stick, if by modding the xorg.conf? or any other way for that matter!

Thanks in advance.

Try
gksudo gedit /etc/X11/xorg.conf
and change the screen section to

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Option "AddARGBGLXVisuals" "True"
Defaultdepth 24
SubSection "Display"
Depth 24
Virtual 1280 1024

EndSubSection

Also, the nvidia tool should be run as root (prompts you for password) and you should click the "Save to X" button or something like that

Hey, thanks. I thought this has to do with something related to xorg beging edited. So I made the Settings Manager generate a xorg.conf for me.Since it wasn't running as root, it wasn't allowing me to save it to xorg.conf. So I copied the contents, opened xorg.conf using the termina, and replaced the entire contents with the one generated by the Server Settings Manager. And touche! i have my 1280x1024 settings with absolutely no issues!
