Viewsonic A91f+ Monitor Setup

I would appreciate help setting up a Viewsonic UltraBrite A91f+ monitor in either Suse 9.1 or Fedora Core 1. X refuses to run at any resolution higher than 640 by 480. Display is spread much wider than monitor at higher resolutions. Attempts at configuring using SaX2 in Suse and manual editing of the xfree86 config file in Fedora have both failed. Link to monitor specs is at http://www.viewsonic.com/products/desktopdisplays/crtmonitors/aseries/a91f/

The monitor specs would tend to suggest that it shouldn't have any problems with any res your video card can support. I'd guess your problem is more likely related to the card. What do you have?

The graphics card is a 64mb 350 mhz Radeon 7000. As an aside, this setup does work fine with Windows XP. My first suspicion is that something about this monitor which just came out is a bit special, and both my and Suse's configuration failed to take that into account.

I'm pretty sure that it is your video card that's the problem. Try a web search for 'radeon 7000 linux' and you see a number of people having problems with that card, even on Fedora Core 2. Given that FC2 is right at the "bleeding edge" in development it is even less likely that the card will work with FC1 or SuSE.

While you may be right, I have had this same system with a previous 17" monitor work well with both Linux operating systems. The Fedora Core 1 installation is the same, but Suse 9.1 has been installed since switching to the Viewsonic monitor.

Here is the relevant current XF86Config file info from Fedora:

Section "Monitor"
      Identifier "Monitor0"
      VendorName "ViewSonic"
      ModelName "Monitor a91f+"
      DisplaySize 1024      768
      HorizSync 30.0 - 86.0
      VertRefresh 50.0 - 180.0
      Option        "dpms"
EndSection

Section "Device"
      Identifier "Videocard0"

The XF86Config file is not there in FC2. You can check out /etc/X11/xorg.config in the same path. Before doing anything, please backup the xorg.config file, so that you are able to restore it back in case of problem.

gtkfreak, thank you for your input. Unfortunately, your suggestion did not work, but I think your solution would have worked with almost all monitors. Also, I did try removing the section from the monitor that specified a 1024 x 768 resolution, but I don't think this was the problem. My monitor is running at 640 x 480, and I would be satisfied if it were to run at 1024 x 768. This monitor seems to be especially stubborn. I plan on trying it with Mandrake on a completely different system to see if I have better results.

I appologize for not closing this earlier. Unfortunately, I never did resolve the issue, but upgrading to FC3 and Suse 9.3 made the problem go away. Gtkfreak provided the info that seemed most germane (the problem apparently was X), hence the accepted answer.
