SUSE KDE lost keyboard

[Alan Gore]

Thanks for the help last week on my problem with getting remote VNC  
access to a new SUSE installation. I found that my problem was an  
overenthusiastic SUSE firewall. Although I checked the firewall port  
open options when I opted in YaST for enabling the VNC ("Remote KDE  
desktop") server. There must be a bug that is causing the wrong port  
to be opened for VNC. I should be able to go into YaST firewall  
configuration and manually open port 5900.

But I've hot a new problem: suddenly, KDE can't see m keyboard. It  
doesn't see any characters I enter, except that the Alt-F4  
combination, which used to close the current window, now pops me out  
to a kernel login. The keyboard works fine here, so I know it's not  
my hardware.

Wiyjout a keyboard in KDE, I can't enter the root password needed to  
get into YaST to reconfigure the firewall. This prevents me from  
getting VNC  access back. Is there a way of disabling the firewall  
without a keyboard, or from he kernel login in which my keyboard stll  
works?
