As I said earlier you need to tweak few things to run this monitor with Intel 810 or 845 based chip-set under Ubuntu Linux.

In order to use higher resolution install updated Intel i8xx, i9xx display driver. It is provided by a package called xserver-xorg-video-intel. This package provides the driver for the Intel i8xx and i9xx family of chipsets, including i810, i815, i830, i845, i855, i865, i915, and i945 series chips.

Replace driver by running the apt-get command. Open your terminal and type command:
$ sudo apt-get install xserver-xorg-video-intel

Now run ddcprobe command to get monitor VertRefresh values and HorizSync rate:
$ sudo ddcprobe | grep monitorrange

monitorrange: 24-82, 50-75

24-82 is your HorizSync rates and the second pair is your VertRefresh (50-75) values.

Next reconfigure xserver (X.org) video and monitor using auto detect feature:
$ sudo dpkg-reconfigure xserver-xorg

Set monitor resolution 1440 x 900 and others as per your requirement. Save the changes and reboot the system.

After login you can adjust screen resolution by visiting System > Preferences > Screen Resolution > Select desired screen resolution such as 1440 x 900 and save the changes.

  1. I have a viewsonic monitor, ubuntu, intel 855gm, 700m dell laptop.

    I installed the intel chipset, changed the vert/h etc.

    1. I can’t switch between my laptop and the viewsonic it is always locked in dual clone mode.

    2. The image on my viewsonic is squished and slightly distorted.

    Any help would be greatly appreciated.

  2. Im about to get a ViewSonic 22″ monitor because its cheaper.
    After reading this Im thinking of getting a Samsung 22″ monitor instead for my Ubuntu 8.04 box.
    But the chipset is Intel Core 2 Quad Q6600.

  3. Thanks for the info for the Viewsonic VG1930wm. It worked perfectly. I’m running Xubuntu 8.04 as I downloaded and installed Ubuntu 8.10 but had display problems. The Wubuntu is pretty good though. Thanks for your help
