I bought a ViewSonic VX1962wm LCD Display today to replace a Compaq 1725 CRT Display.

I am running Ubuntu 7.01 on a Compaq Presario 4838 Model built in late 1990's (1995 or 1996).

No matter what I try I cannot get the resolution greater than 800X600 (only other option is 640X400). No matter what I tried I could not get the CRT resolution past 800X600 either. Under Windows I had 1024X768 with the CRT .

Any help in getting either the LCD or CRT display into a higher screen resolution will be greatly appreciated.

Below is the "Device", "Monitor", and "Screen" sections from my xorg.conf file.

Section "Device"

Identifier "ATI Technologies Inc 3D Rage Pro AGP 1X/2X"

Driver "ati"

BusID "PCI:1:0:0"

Run the Autodetect Script Again

I'm not sure that this is the solution that works for the most people actually, but it most certainly is the quickest and easiest one. All we're doing is running the same script that tried to detect your video hardware when you initially installed. Sometimes this does help, especially if the video card or monitor is different from when you installed Ubuntu. Run the following commands:

Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
md5sum /etc/X11/xorg.conf |sudo tee /var/lib/x11/xorg.conf.md5sum
sudo dpkg-reconfigure xserver-xorg
A configuration page will appear, asking if you want to autodetect video hardware. Select yes, and you should be able to just hit enter a bunch of times to accept the autodetected configurations. After completion, close any open windows or programs you have running on your desktop and press CTRL-ALT-Backspace to restart X. You will be asked to log into your GNOME session again and hopefully everything will be fixed. If not, try the next solution.

This is from this page.

Cheers!
