Just yesterday, I acquired the complete X386 1.1a binary release; I ftp'ed
X11R4fonts.tar, X11R4core.tar.Z, and the tar file that contains the updated
1.1a server and Xconfig file. (Naturally, I replaced the server binary and
Xconfig file with the newer versions.)

My system runs ISC 2.2 UNIX. I have a Paradise VGA 1024 card, which I assume
uses a PVGA1A chipset. My monitor is just a standard 640x480 analog monitor
(not a variable frequency monitor), so I want to use the 640x480x256 mode of
the PVGA1A with panning. I uncommented the appropriate line in Xconfig for
PVGA1A, which follows:

PVGA1A  512   864 606   25 28 36            "640x480"

I commented out all other chipset entries. Then, I commented out all
resolutions except for:

"640x480"   25  640 672 768 800    480 490 492 525

My mouse entry is:

BusMouse 3 "/dev/logi"

(as I said, I have a Logitech bus mouse).

The server comes up just fine (and more quickly than ISC's, I might add :-) ),
except that my screen is "tiled"--a portion of the screen is repeatedly
overlaid all over my monitor. This portion of the screen is itself properly
displayed...it's readable, and the fonts and lines are correct. When I move
the cursor off the edge of the screen, the display pans properly, too. It's
just that the tiling persists.

Does anyone out there have any suggestions as to how I might rectify this
problem? I feel like I'm "so close" to having it all work, but that either some
small bug or some small oversight on my part is responsible for my trouble.

Replies by email appreciated; I'll summarize.
