Inspiron 600m Laptop: trouble getting display on Dell external LCD monitor

[Alain Squindo]

Hello.  I just switched over from Windows to Ubuntu, and I like it so far, 
but there's one thing thats giving me trouble:

I have a Dell Inspiron 600m laptop whose screen has gotten somewhat 
unreliable.  I bought a Dell 17'' LCD monitor (last years' model) in order 
to remedy this problem.  Under Windows, I just plugged in the monitor into 
the laptop's monitor output jack and it worked.  Under Dapper Ubuntu, 
however, the monitor just turns on for a few seconds and then off for a few 
seconds and then on again and so on.  What is the solution to this problem?  
Is there something I need to do with my xorg.config file to get this to 
work?

Thanks in advance for any help,

Alain
