unable to set 1440x900 under Ubuntu 9.10 with Nvidia GForce 7300LE

Hi all,

i'm not able to set the resolution any higher than 800x600. Im using Ubuntu 9.10 with an Nvidia 7300LE PCIe card with a ViewSonic VA1903wb LCD monitor

System info: Linux AMD 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009 x86_64 GNU/Linux
This is a fresh install with updates done.

When I checked through /var/log/Xorg.0.log I can see that the correct card seems to be found.
I want to run 1440x900.

Ive included some parts of the log file and the output of the lshw -C display command that may help.

Thanks!
