adduser - X access?

[Rich <rehartma@artsci.wustl.edu>]

Howdy all,

This is probably a very simple mistake which I am overlooking but I cannot 
find any info - I've added the user"guest" to my home machine so that my 
in-laws can access the internet during the day whilst watching the 
grandkid.... I was going to set up their X Window session that the only icons 
visible were "pon/poff" and "konqueror" - however, I can't even get into X as 
guest... is this a "group" issue? WDM just flashes to the X-screen briefly 
and then back to WDM. Any other issues to make sure that all they can do is 
connect to the net and save files to their own home directory?

thanks in advance,

rich
