I have Ubuntu 12.04 64-bit, GEFORCE GT440, 2 19" VGA monitors with 1280x1024 support. Installed proprietary Nvidia drivers.
% nvidia-xconfig -v
nvidia-xconfig: version 304.43 (buildmeister@swio-display-x86-rhel47-13) Sun Aug 19 21:19:28 PDT 2012
The NVIDIA X Configuration Tool.
This program is used to manipulate X configuration files, specifically to enable NVIDIA X driver functionality.

Now I try to connect the second monitor to videocard via VGA-DVI adapter. It connects only with resolutoin 640x480. Monitor is correct: it displays 1280x1024 when connected to VGA directly. Adapted is correct: tested on Windows machine, it accept 1280x1024.
As I understand, I have troubles in my X11 settings. Here is my xorg.conf:

Any help will be appreciated. I've spent a lot of time trying to run it with normal resolution.
