Hi!
I've been using a voodoo3 2000 quite happily for ages now with
Xfree86, on an old 17" monitor at 1152 pixels across or thereabouts.
Recently that monitor bit the dust, and I replaced it with an iiyama
VM 1451, a 19" monitor capable of doing 1600x1200.
It does 1600x1200 fine, but that's a little bit tricky to read, so I
decided to try the next resolution down, 1400 x 1050. It looks good,
but it flickers a lot: investigation shows that it is running at
60Hz. Weird; surely (I thought) Xfree86 wouldn't deliberately choose
such a low refresh rate.
Turns out it doesn't; but for some reason it doesn't use its 'default'
1400x1050: the following error appears in my xdm.log:
(II) TDFX(0): Not using default mode "1400x1050" (unknown reason)
So I try putting in some modelines by hand. The iiyama's specs
indicate it should be able to do 1400x1050 at something over 80Hz, but
of course it isn't one of the modes advertised by VESA. Two modelines
I came up with are:
# V-freq: 65.00 Hz // h-freq: 71.02 KHz
Modeline "1400x1050" 139.20 1400 1472 1640 1960 1050 1050 1053 1092
# (this one is more like 81Hz)
Modeline "1400x1050@81" 200.00 1400 1432 2184 2216 1050 1069 1083 1103
Both of these are within-spec for the monitor. The monitor's specs
are:
HorizSync 30-96
VertRefresh 50-160
..and max pixel clock 200Mhz
Those two modelines provoke the following errors:
(II) TDFX(0): Not using mode "1400x1050" (unknown reason)
(II) TDFX(0): Not using mode "1400x1050@81" (unknown reason)
My only guess is that it is the video card, not the monitor, that
doesn't want to do those resolutions at those rates?
But the video card *will* do 1400x1050, just only at 60Hz. And it
will do 1600x1200 at some higher frequency (70Hz, or so, I think) -
the video card is specced up to 300Mhz, so it shouldn't be having
trouble keeping up.
This has totally reached the edge of my knowledge of how monitors and
video cards work; perhaps someone else can suggest something? What
does it mean 'not using mode (unknown reason)?'
Below I attach the whole X-server output (note that I am running at
1280x960 now, since I can't get 1400x1050 to work and 1600x1200 is a
bit tough on the eyes).

(protocol Version 11, revision 0, vendor release 6510)
Release Date: 2 June 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)
