Hi,

the problen seems to be the ratio of 4 to 3 of a 17 inch
monitor. Micheal uses a faked DisplaySize entry as 326x260 mm
is definately not the size of his monitor but the ratio of
1280 to 1024. I would suggest you use a resulution with a
ratio of 4 to 3 (i.e 1280x960) and generate a ModeLine for
yourself. you can find a modeline genarator here:
http://koala.ilog.fr/cgi-bin/nph-colas-modelines 

the size of your monitor is normally recognized without an
DisplaySize entry, you can look for in /var/log/XFree86.0.log

auge

[auge at seth auge]$ egrep -i size /var/log/XFree86.0.log 
(II) NV(0): Max H-Image Size [cm]: horiz.: 31  vert.: 23
(II) NV(0): #0: hsize: 640  vsize 480  refresh: 85  vid: 22833

234 mm(--) NV(0): Virtual size is 1024x768 (pitch 1024)

as you see 312/234 is ratio of 4/3

BTW, what  DPI settings do you have?

[auge at seth auge]$ egrep DPI /var/log/XFree86.0.log 
(**) NV(0): DPI set to (83, 83)
