problem with X and keyboard

[Manenti Giovanni <linux@euromatic-automazione.it>]

Hi,
 I've a problem with X. When I try to start X many times it return me an
error. Sometimes it start and when start I've have problem with the
keyboard, I've have modified the xmodmap file but when I press the 'm'
button on the screen write 'm' and after print all the other characters
as I press the 'Caps_Lock' button.

There is a stable X version for ARM?
How can I configure the keyboard in the right way?

Thanks for help
Excuse me for my bad english
