gdmlogin freeze ; nothing interresting in the logs

[shico1973]

after installing Sarge ; X could not start because of some mouse related problem
and i had that message saying that due to a mouse problem X will not start ; and that gdm will be diabled for the moment

as i was searching for a solution i installed gpm that activated the mouse in terminals
and added a couple of lines in XF86Config-4 in the section of the mouse
when i restarted the PC
i saw that X has initialized fine BUT at that moment when gdmlogin was appearing ; a short beep is heard and evry thing
just freezes
no keyboard activity [even numlock ]; no mouse activity and no display actvity [the cursor in gdmlogin textbox does not
blink]
when i try to SSh throgh the network i can login
but nothing interresting in the logs of gdm or XFree86.log
it just ends with
