Blacksceen upon connection via auto launch

[Troy Arnold]

Greetings....

I have searched through the archives and found a few hits on the black 
screen issue but they don't seem to provide any log files or fit to what 
I'm really running into.

I'm running Fedora Core 4 all patched up and have need to have a VNC 
session launch when/if the server reboots or is started up.

I have found two ways to do this:

1) Modify the /etc/rc.local file as such
          su - username -c "/usr/bin/vncserver"
2) Modify the /etc/sysconfig/vncservers file as such
          VNCSERVERS="1:username"

Both of these auto-start types seem to work just fine in that, when I 
start the server and I look for the process I see it running.

*IE:  *

/[arnoldt "at" PCH0-HIS23-Linux ~]$ ps aux | grep vnc
arnoldt   3437  0.0  0.7  7096 3820 ?        S    13:10   0:00 Xvnc :1 
-desktop PCH0-HIS23-Linux.cvmc.org:1 (arnoldt) -httpd 
/usr/share/vnc/classes -auth /home/arnoldt/.Xauthority -geometry 
1024x768 -depth 16 -rfbwait 30000 -rfbauth /home/arnoldt/.vnc/passwd 
-rfbport 5901 -pn/


Now.. if I test this setup, and reboot the Linux machine... as stated 
above, the VNC process for my user starts fine.  I then go to connect 
and find I only see a black screen.

I found this odd so from this point I would kill the PID and launch 
vncserver manually from /usr/bin.  When I did this the vncserver process 
started just fine, and when I goto connect everything works fine.

*Outputs:*

/[arnoldt "at" PCH0-HIS23-Linux ~]$ cd /usr/bin
[arnoldt "at" PCH0-HIS23-Linux bin]$ ./vncserver

New 'PCH0-HIS23-Linux.cvmc.org:1 (arnoldt)' desktop is 
PCH0-HIS23-Linux.cvmc.org:1

Starting applications specified in /home/arnoldt/.vnc/xstartup
Log file is /home/arnoldt/.vnc/PCH0-HIS23-Linux.cvmc.org:1.log/

*ps aux | grep vnc from a manual launch:*

/[arnoldt "at" PCH0-HIS23-Linux bin]$ ps aux | grep vnc
arnoldt   4343  0.2  1.6 11608 8136 pts/1    S    13:12   0:00 Xvnc :1 
-desktop PCH0-HIS23-Linux.cvmc.org:1 (arnoldt) -httpd 
/usr/share/vnc/classes -auth /home/arnoldt/.Xauthority -geometry 
1024x768 -depth 16 -rfbwait 30000 -rfbauth /home/arnoldt/.vnc/passwd 
-rfbport 5901 -pn/


I have the logfile here for review.  Note this is the log file from the 
server after it reboots, and not before I manually launch vncserver.

*Output:*
