xorg uses wrong resolution for internal lcd

Tue May 6 23:36:00 UTC 2008

hi,

i've been using ubuntu for a long time and at some point during the
hardy release cycle - which i started tracking in february or march --
the display resolution got messed up on my laptop's internal lcd.  this
is a dell d820, running the non-free nvidia driver on an geforce go 7400
graphics card.  the monitor is 1920x1200, a resolution that has always
worked for me in earlier versions, but on startup and login -- so both
at the gdm prompt and an a gnome session -- the resolution is stuck at
1024x800.  i've gone through my xorg.conf -- attached below -- and tried
at every opportunity to insert lines forcing a 1920x1200 resolution, but
it has never worked.  

i can reset resolution with displayconfig-gtk, but the changes do not
persist, even though i use the 'save changes' button & never see error
messages when running  from the command line.  

anyway, if there are any suggestions, i'd love to hear them.  thanks!

matt
