On all Dell Workstation systems, shipped into EMEA, and I believe the US, they include the Diamond Viper Video card. This Viper card uses the Riva TNT2 chipset. From the Factory (EMF) Xconfigurator is setup with a default res of 1024x768. If the user, reruns Xconfigurator, the chipset detected is SVGA and the resolution when X windows is started (regardless of what resolution the user selected) is 320x200. The only way to fix this is to manually edit the XF86Config file to add a chipset line. DellPLUS engineers in Europe believe this is a bug in Xconfigurators card database. Could this be resolved for the 6.1 release
The RIVA TNT2 driver is included in the SVGA server as of XFree86 3.3.5. There will be a forthcoming errata release for all versions of this release of X, and it will of course be included in the next release.
