It seems like it's Toshiba Satellite 1800.

The search gave me the address (4th link) which is "Linux on the Toshiba Satellite 1800-S203" and 
there is Ubuntu used for example and this article is written on 24th June 2008, so quite fresh story.

There is also exact xorg.conf written down - perhaps can you get some ideas from there. I will not 
copy whole example here - you can read it yourself and test that xorg.conf
Be sure you will do backup at first from your original xorg.conf file:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg_original.conf

It seems like this laptop is using some kind of trident device as graphic card and kernel driver 
module name is also trident.

I tried this search -

... and results: - same problem with same laptop - here is one solution for you

Read carefully these forums - there are different experiences from different people - you have just 
try these different solutions to find out, what is best for your laptop.

E.g. here - is another xorg.conf example for 
you - try this.

And keep in mind, that if X will not start, then use CTRL+ALT+F1...F6 to get console and ALT+F1...F6 
to switch between virtual consoles at terminal. ALT+F7 will get you back into X session at display :0
Also there is useful to have in GRUB recovery mode - then you will get your laptop booted even when 
X is not working. Actually you should get your laptop booted even if X will not start. You will be 
just noticed, that there was some problems during X start and you will get terminal to log in.

Also investigate log files:
/var/log/Xorg.0.log - main log file examining X errors
/var/log/messages - there will be also system messages about X behaviour
/var/log/debug - also there might be some messages
/var/log/kdm.log - K Display Manager log might also give some information (if you use KDE)
