I have a Dell Latitude D620 laptop. It is a widescreen. I need it to go to a 1440x990 screen resolution in Ubuntu 6.06 and recognize my Intel i945 graphical chipset. I have used SuSE 10.1 and it automagically detected the video card and resolution.

I also can't edit the xorg by doing the dpkg-reconfigure command. It says it is not installed. I am new to Ubuntu. I like it and hate at the same time

Can't you manually edit your /etc/X11/xorg.config file with a text editor? (make a backup first).

What video driver do I use? currently it's set to VESA and vesa does not support 1440x990.

I googled up on how to get 1440x990 on Ubuntu and I got a lot of results which confused me, such as downloading the resolution915 package, then using dpkg-reconfigure (which doesn't exist for me) and then editing my /etc/X11/xorg.conf file. Unfortunately I haven't found any details yet.

Just type in console ::Select your resolution with spacebar
close with Enter

Then do Ctrl + Alt + Backspace to go to a real terminal
there type " startx "

You did not read my post thoroughly. Currently my video driver is set to a VESA driver. Vesa does NOT support resolutions above 1024x768. Even when I set it manually in the xorg.conf file, it shoots it right back to 1024x768.

You might try looking in the kernel documentation ( in /usr/src/linux/Documentation/ ) and see if there is documentation on the i810 driver. It might support i945, but I don't really know.

There is a gtf program that you can use to generate modelines:
gtf 1400 990 60 -x
for example will generate a "1440x990_60.00" modeline that you can use in xorg.conf.
This may be useful after resolving the driver issue.

I solved my resolution problem and hopefully this will help other newbies, or folks with a Latitude D620 who want to get 1440x990 resolution. The whole cruxed of the problem was that by my default installation and setup, the "i810" video driver would never get recognized, even if I manually edited the /etc/X11/xorg.conf file (X server errors). Even reinstalling the i810 video driver from the Synaptics Package Manager would not recognize the "i810" video driver. Solution:

1) Go to SYSTEM->Administration->Software Properties
2) Make sure you check box the UNIVERSAL respositories
3) open terminal
4) sudo apt-get install 915resolution
5) sudo gedit /etc/default/915resolution. In that file, X=1440, y=990
6) sudo dpkg-reconfigure xorg
7) I selected the i810 video driver with the "generic monitor" at 1440x900 @ 24 bit depth.
8) I saved and rebooted the system and my widescreen was all set!

Now the next big step: get my Broadcom wireless card to work on this D620 laptop!
