Red Hat 5.2 X-Windows

have you tried running Xconfigurator?

There are two factors to consider when customizing the X windows configuration.
1. Type of Monitor and the maximum vertical and horizontal settings. This is done in megahertz. Many of the popular brands can be selected from the custom setup in Xconfigurator.
2. Type of display card. In order to get true color you will need to have at least 4Mb of video ram. Most SVGA cards will take the setting of 800x600 during the custom configuration.
Once you have determined these two factors you can runXconfigurator and make the selection of the above. There will be a default setting that will show for your selections. At this point you can select the appropriate setting that you require.
For additional information you can look at the man pages for X and Xconfigurator.

I suggest you download a more recent version of Redhat. Version 7.1 (the latest) should figure out what the best settings are for your video card - installation and customisation on 7.1 is a lot easier than with 5.2.

From prompt in a terminal in x, launch xvidtune. It allows you to adjust the size of the viewable desktop and outputs the correct settings to place in your XF86Config files. There's a way to have it automatically be entered in XF86Config, but I haven't figured it out. I just copy the settings to paper or cut and paste if gpm is installed, and enter them into the [screens] section.

I have had to do this on just about every RH Linux install I've ever done.

Cheers,
BB
