After updating RedHat 9 on my system, my monitor display gets completely messed up. I have an iiyama Vision Master Pro 454 (which is not a known monitor in the configurator). The display is now larger than the screen. I have to move my mouse to the edges of the monitor to display the rest of the desktop. All items are extremely large. Changing the resolution to 640x480 will cause the entire desktop to appear on the screen, but all the icons are still very large and things overlap (making most illegible).

Has anyone encountered this problem and corrected it?

Check your /etc/X11/XF86Config file using your favorite text editor. Look for your display settings sections, it should look similar to this:

Go to your default depth section (like that one above) and make sure you've got this in there:

ViewPort 0 0

So it should look like this when you're done:

This seems to be what your problem is. If the view port is not set to "0 0" then you'll get the same symptoms. Also, check to see if you have any lines such as

Virtual "1280x1024"

This could cause problems too if you don't have it set the way you want it. Hope this helps.

I'll give that a shot! Thanks.

Oh, by the way, reinstalling rh 9 removes the problem, but updating recreates it. After trying to update packages individually, it appears that the XF86 configuration package is at the root of the problem. Hopefully changing those lines will correct it.

Keep us posted.
