Len's right.  But there might be another problem.

In the past, and probably still, the Intel chipset X video driver will
only support resolutions that the BIOS supports (for a VGA mode).
Stupidly, many laptops do not have a BIOS-supported resolution
matching the native resolution of the display panel!

There is a fudge to get around this: the program 915resolution.  I
think that Ubuntu actually includes this as an optional program.
Roughly:

- when invoked appropriately, it overwrites the RAM copy of the BIOS,
  replacing selected resolution entries.

- invoking it this way is done best in something that gets run during
  booting like rc.local (I'm not sure if that is the right file on
  Ubuntu).  The command "locate 915resolution" might be interesting
  (it is on my notebook with older Ubuntu.)
