Description Tim Waugh 2004-11-17 16:59:13 UTC 
User-Agent:       
Build Identifier: 

If a vncserver is configured on :1 in /etc/sysconfig/vncservers, RHGB prevents
it from starting because it occupies that display number while the vncserver
initscript runs.

You could do something like the following to figure out the lowest free display
for RHGB to use:

declare -a displays
for n in $VNCSERVERS
do
  displays[${n%:*}]=${n#*:}
done
for n in $(seq 1 99)
do
  if [ -z "${displays[$n]}" ]
  then
    echo $n
    break
  fi
done


Reproducible: Always
Steps to Reproduce:
1. Put VNCSERVERS="1:root" in /etc/sysconfig/vncservers
2. Boot with 'rhgb' on the command line

Actual Results:  
No VNC session on display :1.

Expected Results:  
Root's VNC session on display :1.

Considered fixed in 0.16.1 pushed as an errata, it now uses display :9
