I recently installed ubuntu 8.10 desktop on my pentium 4 server. along with the other server essentials I installed, (apache2, php, etc.) I used apt-get and installed vnc4server and xinetd. whenever I start a vncserver, log into it using real vnc viewer on my XP machine, and I get the gray screen with a white shell window. why is this? is there any way to remove all of this and start over, or If I do a reformat, is there any way to prevent this from happening again? thanks
