Geoff,
I had exactly the same problem when I installed Linux. I have solved
it and I can get X working, although I'm sure my setup is far from
optimised, like you I am new to linux.
If you type startx then read the output as X starts (or
doesn't as in your case) you'll notice statements something like
Vert refresh 71Mhz need 68.7Mhtz
If you then add the new value (68.7 in above example) to your
XF86Config file and do this for all the wrong values X moans about
your final XF86Config file should then start X up. It did with me
anyway. I've got a Tpad 755CE and I think the video hardware is much
the same.
For your information the relevant values from my XF86Config file
follow, but maybe you should ascertain values from the X output first
and use my values if that fails.
Good Luck
Pete
