Frank. You have only one ModeLine in your configuration (let's
assume it could work for your monitor). The ModeLine asks for a
dot clock of 48.00 MHz (1st number). At 1024x768, this results
in a horizontal frequency of (very roughly) 48MHz/1024 ~ 47kHz
and a vertical refresh rate in the order of 47kHz/768 ~ 60Hz.
(Note: the exact numbers are different [syncing]). However,
your VertRefresh/HorizSync parameter settings disagree with
the values resulting from the ModeLine - hence the Server
must reject it.

Note: HorizSync / VertRefresh should specify the _range_
your monitor is able to handle; a single entry is likely to=20
be too restrictive.

Try:

HorizSync 30-60
VertRefresh 58-65

(BTW I use=20
Modeline "1024x768" 66.00 1024 1040 1216 1328 768 768 775 802
on my TP600E)

Sorry for the long explanation; good luck with your girlfriend
(I gotta get off-line now otherwise I'll get real trouble here...)

Till.
