Please attach full X server log and config file via the link below.
The console output from the server begins like this his is a pre-release version of XFree86, and is not supported in any way. Bugs may be reported to XFree86@XFree86.Org and patches submitted to fixes@XFree86.Org. Before reporting bugs in pre-release versions, please check the latest version in the XFree86 CVS repository (http://www.XFree86.Org/cvs) XFree86 Version 4.1.0.1 (Red Hat Linux release: 4.1.0-0.9.13) / X Window System (protocol Version 11, revision 0, vendor release 6510) Release Date: xx August 2001 If the server is older than 6-12 months, or if your card is newer than the above date, look for a newer version before reporting problems. (See http://www.XFree86.Org/FAQ) Build Operating System: Linux 2.4.7-0.13.1smp i686 [ELF] Build Host: stripples.devel.redhat.com So this establishes that /etc/X11/X was linked to XFree86, yes? So I ran Xconfigurator. It produced an XF86Config that worked (gave desired resolution) and was different than the one I was using. On checking, I discovered that /etc/X11/X was linked to XF86_SVGA. I re-linked to XFree86, and my XF86Config now works. SoI'm happy, but I'm sure puzzled. Was some entity fiddling with /etc/X11/X?
In Red Hat Linux you do not ever have to symlink the X server, nor should you ever do so. Xconfigurator handles the symlinks that are needed on its own, and ensures that the X server is properly getting started via Xwrapper. Overriding this will cause problems, various breakage and unexpected behaviour, and result in a setup which is not supported by Red Hat. As long as you do a fresh install of X, and use Xconfigurator for configuration, the symlinks will remain sane. For advanced configuration look at the Xconfigurator manpage as well. There are many features on both the commandline, and in the interactive mode, of which some are not immediately obvious. Hope this helps.
