If you're saying yes to all questions it could be trying to use a 
resolution that isn't suitable for your monitor (I've seen this on my 
other half's desktop with a 15" LCD, it tries to use a default of 
1280x1024!).

Did you select the right graphics card driver?

Maybe using vesa might work?

When you get to the video modes used by the X server (it's in the 
monitor configuration), try scrolling down the list.

On my machine it has a asterisk next to 1280x1024, 1152x864, 1024x768, 
800x600 and 640x480.  Looks a bit like this...

[*] 1280x1024
[ ] 1280x800
[ ] 1280x768
[ ] 1200x800
[*] 1152x864
[ ] 1152x768
[*] 1024x768
[*] 800x600
[*] 640x480

It might be worth de-selecting anything higher than 1024x768 (just 
select the item from the list and press the space bar to select/deselect 
an item).

When it comes to selecting monitor characteristics, try using the Simple 
selection and selecting the size nearest to your screen size (if it's a 
TFT monitor you *might* get away with selecting the next size up).

After you've reconfigured X, don't forget to restart gdm (or just issue 
the command startx at the command line prompt to give it a try).  If you 
get any error messages, try and post them if you can.

Anyway, hope this helps.
