I have been using Lubuntu 12.04, at resolution 1440x900. Then I got Rawtherapee, but it would not work right. So I ran a Live Lubuntu 12.10 and the resolution was at 1440x900. So I up-graded to 12.10 and now I cannot get above 1024x768.

Puppy 5.28 automatic see 1024x768.

My card is nVidia GT440. I looked at the nvidia x server settings menu and it said:

You do not appear to be running the NVIDIA driver.

So I ran nvidia-xconfig. Now I got a xorg.conf file. Did not have one before, but the Live Lubuntu 12.10 did not have a xorg.conf and it ran OK.

Nvidia X Server said:

You do not appear to be running the NVIDIA driver.

Where is "Additional Drivers" in Lubuntu? Before I installed the drivers in Lubuntu 12.04. But I do not remember how I did it.

Output of dpkg -1 nvidia-\*:

If nothing else works, you may consider backing up your data and then doing a clean re-install of 12.10 over the "upgrade". It maybe that something carried over from the previous install isn't letting you get the resolution you need. –  user25656 Jan 11 '13 at 2:38

Did Nvidia X Server Settings say you were running the Nvidia driver, after you ran nvidia-xconfig? If not, is there anything available in Additional Drivers? How exactly had you installed the NVidia drivers before? When you installed them was that in Ubuntu 12.10 or was that in an even earlier version? What's the output of dpkg -l nvidia-\*? Please edit your question to provide all this information. –  Eliah Kagan Jan 11 '13 at 3:19
