Fuzzy - is this fuzzy(blurred) fuzzy(Lines across, or what? The first is a
monitor problem, the second interlacing.
First of all, when sorting this sort of thing, do the obvious: Have you
shifted from pci card to agp? Is your pc talking nicely to the agp slot? I
had some BIOS settings that screwed that up for me. Have you given the
maximum possible dotclock for the card, horiz. & vert frequencies for the
monitor? Have you killed off any fancy options for the SiS card (fast_vram
I would resort to using XF86Config, instead of XF86Config-4. That has a
standard set of modelines, and you can hack these by hand. This one
# 640x480 @ 60 Hz, 31.5 kHz hsync
Modeline "640x480" 25.175 640 664 760 800 480 491 493 525
should be your monitor setting for a console, unless you have a vga= line in
lilo or whatever you use. That should work on any box. You'll want 640x480,
800x600, 1024x768, mebbe 1280x1024. Check your max monitor frequencies, and
go in with the fastest lines under it. Use no interlaced modes (X finds
excuses to reject them). Cut XF86Config to those 3 0r 4 lines
# startx >xerrors 2>&1
# less xerrors
What's going on? check all 3 modes with Ctrl_Alt_+. Let us know and we'll
sort it. If you're unemployed, totally idle, and insomniac, and a compulsive
reader, you could read the video timings HOWTO, which would be the 'TFM' in

Don't worry. She'll love to see you caught out this way.
