I am using a MAG MX17F temporarily while a MAG DX17F is being repaired.

I had expected the MX would run with the XF86Config file I use for the
DX, but it comes up in 640 by 480, and nothing else.  One possible
culprit is the intelligence of the MX, which has a bunch of preset or
user programmable modes where Horiz and Vert frequencies are set.  It
has an LED display that allows selection among eight modes, most of
which appear presently to be the same: H=39.25 KHz, V=74Hz.  Possibly 
these overide the values in the XF86Config file.  The MX has specs of 
Bandwidth = 120, V-scan of 50-120, and H-scan of 30-68.

The DX17F works fine with the ATI Mach64 (2 Meg) so the board and the
Device section of the Config file are fine.

In any case, I hope someone may have some familiarity with the MAG MX17F
and may be able to help with some explanations and suggestions for
getting it to respond to other modes, and possibly even some Config 
models for 1024x768, 1280x1024, 1152x900 or other modes.

PS: Although I will check the newsgroup, I would appreciate email too.
