A few months back I installed 12.04 on a separate hard drive just to keep track of developments. during that time I noticed that the resolution was not great, everything seemed just a little blurry. Not by huge amounts but just enough to notice it especially after switching from my main 11.10 install.
I didn't take a lot of notice as 12.04 was still in its development stage, however now that I have upgraded my primary hard drive to 12.04 final I now have the issue permanently.
My graphics card is an Nvidia GeForce 9300 GE. I have tried both drivers available to me (no change)
Something that does work however is if I change the refresh rate via Nvidia settings. It defaults to 75Hz which I can change to auto or 60Hz, if I make the change to either of those the problem is solved. Even though I am saving the settings to /etc/X11/xorg.conf if I log out or reboot it defaults back to 75Hz. How can I make this change permanent or should I be looking at changing something else?
Thanks for your help
