[mythtv-users] Mythfrontend Refuses to Start

[Kirk Bocek]

Just upgraded from 0.24 to 0.27.4 and one of my two frontends refused to 
run mythfrontend.

My setup on both boxes is to auto-login to the mythtv user. 
.bash_profile looks like:

export __GL_SYNC_TO_VBLANK=1

if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty7 ]; then
while [ 1 == 1 ]
      do
           startx
           sleep 4
      done
fi

.xinitrc looks like:

xset -dpms s off
xsetroot -solid black
xhost +
#See nvidia readme:
export __GL_SYNC_TO_VBLANK=1
#/usr/bin/pkill irexec
#/usr/bin/irexec -d /var/lib/mythtv/.lircrc
#mythfrontend -v all -l /var/log/mythtv/mythfrontend.log
/usr/bin/mythfrontend --logpath=/var/log/mythtv
#/usr/bin/mythtv-setup --logpath=/var/log/mythtv
#xterm

But mythfrontend refuses to start at all. Nothing in /var/log/mythtv. X 
is running and finding my display:

But no mythfrontend:

$ps -ef

mythtv    5356  2106  0 10:43 tty7     00:00:00 /bin/sh /usr/bin/startx
mythtv    5372  5356  0 10:43 tty7     00:00:00 xinit

/var/lib/mythtv/.serverauth.5356

Now if I run vncserver, and execute mythfrontend from a terminal, it 
executes just fine. But it won't run here. And I've got a second host 
using the same configuration that is working just fine.

Does anyone have any suggestions?
