F11: low video resolution

[lanas]

Hello again,

  After the install and update (close to 600 packages were updated)  of
Fedora 11 x86_64 there is seemingly no way to specify which video adapter there is nor to specify which monitor is being used.  Hence, the resolution is low at 1280xSomething.  The video adapter is on-board and is a Nvidia.  How can the video adapter and monitor be specified.  I reckon they should be automagically detected, but there are not.

  Thanks for any suggestions.
