If you're interested, you could try removing the check and see what happens. Note that there is a patch (debian/patches/02_tdfx_improve_mode_rejection_diagnostics.diff) which modifies the code to add some messages.

This was not easy to check because my tdfx configuration was asleep in a
closet. Anyway I did a fresh Etch install on it and can report now.
The bug is still here, though I have some news: the "unknown reason" is
still here but there a line just before saying
"rejecting mode with horizontal resolution 1400 not divisibile by 16 and
clock 179260 greater than 135000"
(check the joined logs / configs)
Of course 1400 isn't a multiple of 16 but I know it's not a hardware
constraint. Additionally I tested with no explicit modeline and it works
out a 1400x1050 @ 60 Hz resolution ! (see t1/*)
I don't know where the 135000 comes from... but it's totally not coherent.
It has picked up 1280x960 @ 85 Hz which works at 148.5 MHz. The card has
aXorg.0.log clock range (logged) from 12 to 270 MHz which is far enough to
display themode I wanted.
And the DRI is still disabled at hi-res :( ... well that's another bug.
Joined config & logs: xtests.tar.bz2 contains xtests/t{1,2}/
{xorg.conf,Xorg.0.log}. t1 has no modeline and displays 1400x1050 @ 60Hz,
while t2 has an explicit modeline and only displays at 1280x960.

Hope this helps,

Hi, About 2 years ago, you reported a bug to the Debian BTS regarding the 3dfx driver not accepting 1400x1050 resolution. Did you reproduce this problem recently? With Xorg/Etch? If not, I will close this bug in the next weeks. Thanks, Brice -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
