How to set proper resolution for Viewsonic flat panel display?

Asked by David M. Schmidt

I recently installed a Viewsonic VA1916W 19" flat panel display. The display documentation states that the resolution should be set to 1440 x 900. However, when I open System|Preferences|Screen Resolution, the only resolution options available in the pull-down menu are:
1280 x 1024, 1024 x 768, 800 x 600, 640 x 480, 1280 x 960, 1280 x 800, 1152 x 864, 1280 x 768, 1152 x 768, 928 x 696, 896 x 672, 960 x 600, and 832 x 624.

What do I need to do to be able to set the resolution to 1440 x 900?

The display is installed on a Systemax "Ascent" PC clone with an AMD "Athlon" family 6, model 4 processor running at 848 MHz with 256 kb cache and 768 Mb RAM. The VGA controller is a Silicon Integrated Systems 86C326 5598/6326 with 8257 kb. The operating system is Ubuntu 6.06 LTS.

Thanks,

Dave

David M. Schmidt,

Try adding the resolution to /etc/X11/xorg.conf file.
Before doing that, lets make a backup of your working copy.
Fire up a terminal (Applications>Accessories>Terminal) and enter the following code:

sudo cp -v /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Now Edit the file using sudo gedit /etc/X11/xorg.conf
Add the resolution 1440x900 at the section "Screen", subsection "Display".
Save the file. Press ctrl + alt + backspace. Login in and try changing the resolution from System>Preferences>Screen Resolution.

If that doesn't work, then:
Press ctrl + alt + f1. You'll see a terminal. login using your username and password.
Enter the following commands after logging in:
sudo /etc/init.d/gdm stop

sudo dpkg-reconfigure xserver-xorg
Follow the instructions. Don't forget to select 1440x900 when asked for monitor resolution.

After the configuration is finished,
sudo /etc/init.d/gdm start and then
startx

With Regards,
Zombie.
