>> I have problems to configure my X window system in my thinkpad IBM 560.
There is more than one model of the IBM ThinkPad 560 so this might not
apply to you. I have a ThinkPad 560Z with X running great on it (at
800x600x16). I wrote my experiences up on a web page including the
XF86Config file. You can find it at
http://www.math.psu.edu/dna/tp560z-linux.html
There are also links on that page to the Linux on ThinkPads page and to
the Linux on Laptops page, both of which list the configurations for a
variety of TP 560s.
Good luck.
