Public bug reported:

Binary package hint: xorg

I have a Dell Latitude E4310 with the latest ubuntu release (10.10)

output of uname -a:
2.6.35-23-generic #36-Ubuntu SMP Tue Oct 26 17:13:06 UTC 2010 x86_64 GNU/Linux

My LCD display appears only on 1366x768 resolution, no possibility of
changing it,  and this causes problems when I attach an external monitor
(by the way, it detects the external monitor perfecctly) because I
cannot do cloning. I have been using linux for many years but my
knowledge is a bit rusty. I would like to add some more modelines but is
not clear to me how to do it since there is no xorg.conf file and I want
to avoid making a mess.

I know that there are similar bugs reported and answered:

https://wiki.ubuntu.com/X/Troubleshooting/Resolution#Problem:
Resolution with Intel graphics was correct in Intrepid or Jaunty (with
no xorg.conf configuration) but is limited in Karmic

but it is not clear if they give the answer to my question: the computer
is brand new and I have not tried any other distribution on it.

Any help is appreciated:
