Are you using TwinView or Separate X Screen?  I have the T61 6459-CTO (LCD
1680x1050)and have a Samsung 226cw external LCD (with 1680x1050).  I have
already upgraded my BIOS to 1.26 this morning, and I am using the nvidia
driver.  I used nvidia-settings to set it up with TwinView as a clone of my
LCD.  If I set the resolution of the Samsung to 1280x1024, it works fine,
but with scrolling. =20

If I try to set the resolution to 1680x1050, as soon as I restart X, the
Ubuntu login box comes up but the entire computer locks up and I have to do
a hard-restart.  Any idea why the nvidia driver can't output to an external
monitor at its native resolution?

I can't find anything in any logs indicating what is happening.  Here is th=
