X doesn't start after installing debian

[Jan Brosius <jan.brosius@skynet.be>]

Hello,


I installed debian 4.0 r3 amd64 on my laptop an Acer Aspire 9920. The 
graphic card is Nvidia 8600M.
The installation went well until after the reboot. Then the X server 
didn't start. I installed then with apt the debian package n"vidia-glx". 
But when I then start X I get a blank screen  and I don't  even get  a 
console input.

I there nothing I can do to install debian on my laptop.

Thanks for any help
Jan
