[mythtv] Autostart myth + KDE 3.x

[William Preston]

I'm having a bit of a tricky time getting myth backend and frontend to
start with KDE.  Yes, I know the 'simple' way to do it with a different
window manager, but I'd prefer to run KDE.

So this is what I've got going:

--
>cat go.sh
#!/bin/bash
/usr/local/bin/x10remoted &
/bin/sleep 30          //wait for windowmanager to start up
/usr/local/bin/mythbackend > ~/mythbackend.log 2>&1 &
amixer set Line,0 70%,70% mute capture
/bin/sleep 5
/usr/local/bin/mythfrontend > ~/mythfrontend.log 2>&1 &
--

I've tried running this via .xinitrc, and via the 'autostart' thinger in
KDE (which creates a symlink to the shell script.)  The script runs either
way, but regardless of the sleep command (no matter how long I have it
wait) I always get this when mythbackend attempts to start:

Loading required GL library /usr/X11R6/lib/libGL.so.1.2

Do I simply need to use a different shell, insert an include line, or use
some other trickery to getting it going?  Sorry if this is simple...I'm
not too swift at shell scripting.
