Comment 27 for bug 63551

I have Ubuntu Feisty 7.04, nvidia chipset and a Dell 2007WFP 20 inch widescreen monitor.
I was able to get the 1680 x 1050 pixels resolution without manual editing as follows:
1. install package nvidia-glx-new
2. enable the driver: sudo nvidia-glx-config enable
3. generate new xorg.conf: sudo dpkg-reconfigure -phigh xserver-xorg
Apparently, the problem is that the new driver is not officially supported by ubuntu.
