[mythtv-users] Re: VNC launches second mythfrontend

[Aaron Stewart]

Silly question, but would it be better to determine whether mythfrontend
is running before running a second one?

e.g.

MYTHFRONTEXEC="mythfrontend"
MYTHRUNNING=`ps ax | grep '$MYTHFRONTEXEC'`
if [ "x$MYTHRUNNING" == "x" ]; then
    nvidia-settings -l
    mythfrontend
fi
