hi,
i'm trying to setup my system so that it allows using mythtv on the tv and a regular gnome session on the monitor.
my xorg.conf:
| Code: | Section "Module"
Load "dbe"
SubSection "extmod"
Option "omit xfree86-dga"
EndSubSection
Load "glx"
EndSection
Section "Files"

and i use this script to startup myth on the tv:
| Code: | #!/bin/bash
DISPLAY_NO=":1"
LAYOUT_NAME="Layout1"
X $DISPLAY_NO -ac -layout $LAYOUT_NAME &
sleep 5
X_PID=`ps aux | grep "X $DISPLAY_NO" | grep root | tr -s " " | cut -d " " -f2`
export DISPLAY=:1
mythfrontend &
~/.config/openbox/exec &
openbox
kill $X_PID
exit 0 |
~/.config/openbox/exec & just contains a line to get rid of the blue lines in ogle which has to be run after openbox is loaded.
this does not allow 2 simultanious x-servers but that is a problem for later.
i have 2 soundcards, the first is for gnome(/dev/dsp) and the second for mythtv(/dev/dsp1).
they both work but i have a problem with openbox:
first i did not use openbox because myth spans to the whole screen but i had the problem of losing my keyboard input when launching mplayer in myth.
this was solved by using a window manager(openbox).
i have set the audio output in myth to /dev/dsp1 and it worked well without openbox, but with openbox the sound is always redirected to /dev/dsp no matter the configuration in myth.
could it be that openbox always uses the default audio output? and how to change that? maybe an ~/.asoundrc that only allows playback on /dev/dsp1
or maybe use another wm, if it really should be openbox that causes this?
