This "How-To" guide is for instruction on getting both VGA and composite working on a Fedora Core 6 MythTV box with a remote control button. One display at a time, but both work.
Contents
Introduction
This guide is based after installing with Jarod Wilson's how to guide which you can find here.
I stopped with Jarod's install instructions at the rebuilding of the ram-disk. If you have gotten that far, you should have a box that once worked with VGA and currently works with the composite out. This document covers how to get both to work and how to get the PVR-350 remote to switch between the two.
How to VGA and Composite with a PVR-350 on FC6
- Create a second user account to run X with. In my case, I'm using "mythtv" and "mythtv-composite". You could use the system config tool to set up the users
# system-config-users
- Create a symbolic link to your mythfrontend binary, in the same directory, called mythfrontend-composite. This unique name allows the script to know if both copies are running.
# ln -s /usr/bin/mythfrontend /usr/bin/mythfrontend-composite
- Make changes to X. Fist backup your current xorg.conf
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orginal
Now use the system config tools to get your VGA display going again.
# system-config-display
Then add a separate "ServerLayout" section in your Xorg.conf file, for the PVR card. Its name is referenced in the video select script. Below is an example that uses "NTSCLayout" for the layout identifier.
from my /etc/X11/xorg.conf I have this addition
# Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" ModelName "Monitor 1024x768" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 31.5 - 57.0 VertRefresh 50.0 - 70.0 Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "r128" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" "800x600" "640x480" EndSubSection EndSection # Added for TV out options with MythTV Section "ServerLayout" Identifier "NTSCLayout" Screen 1 "ScreenNTSC" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Files" # RgbPath is the location of the RGB database.

Once you have appended this look it over and make sure there aren't conflict's or missing sections. Specifically look closely at keyboard and mouse configs. The rest should be unique enough to avoid problems. Also be careful with items like system-config-display, it will often blows away your modified file.
- Download and install wmctrl
# yum -y install wmctrl
- setup the video select script by creating /usr/local/bin/start-script and modifying it to your needs. Here is my current script.
#!/bin/sh vt=8 prog=mythfrontend-composite disp=':1.0' disp_short=':1' user=mythtv-composite note=upstairs dev=/dev/dsp args='-layout NTSCLayout -dpi 100' vscan='0' hscan='0' yscan='0' guioffsetx='34' guiheight='464' guiwidth='658' painter='qt' debug='/dev/pts/1' echo "start-script" > $debug if [ "$1" != '-composite' ] ; then # normal operation vt=7 prog=mythfrontend disp=':0.0' disp_short=':0' user=mythtv note=downstairs dev=ALSA:default args='' vscan='3' hscan='6' yscan='13' guioffsetx='0' guiheight='0' guiwidth='0' painter='qt' fi # start X if not already running gotx=`ps h -C X | grep " $disp_short "` echo "gotx is next" $args > $debug echo ${gotx}X > $debug if [ "${gotx}X" = 'X' ] ; then echo "no X so startx --" $disp_short $args "vt is" $vt > $debug echo -n 1 > /var/run/console/$user su -c -l - $user "startx -- $disp_short $args &" chvt $vt sleep 2 else echo "X is running so vt" $vt > /dev/pts/2 # it's already running, so just switch the VT chvt $vt fi echo "just switched X over" > $debug ## start mythfrontend, or make it the topmost app #pid=`/sbin/pidof $prog` #export DISPLAY=$disp #export XAUTHORITY="/home/$user/.Xauthority" #if [ "${pid}X" = 'X' ] ; then # echo "Starting frontend for $note TV" # su -c -l - $user "exec gnome-terminal -e '$prog' &" #else # # make it topmost # wmctrl -a $prog #fi # update the DB #echo \ #"update settings set data='$guioffsetx' where value='GuiOffsetX';" \ #"update settings set data='$guiheight' where value='GuiHeight';" \ #"update settings set data='$guiwidth' where value='GuiWidth';" \ #"update settings set data='$painter' where value='ThemePainter';" \ #"update settings set data='$dev' where value='AudioOutputDevice';" \ #| mysql --password=mythtv -u mythtv mythconverg
I've commented out the Myth stuff for now. Once you get X switching correctly, then you can add the Myth sections. when you are working on the Myth stuff, modify the script to make any additional DB changes.
- Get irexec working and automatic, by editing /etc/rc.d/rc.local. I added this line to the bottom
/usr/sbin/lircd --device=/dev/lirc0 --output=/dev/lircd /usr/bin/irexec /home/mythtv/.mythtv/lircrc &
You should check that the lirc0 and lircd are correct. Don't forget to disable lirc from the services.
# chkconfig --level 2345 lircd off
Now it's probably best to reboot to make sure it will start correctly. To confirm the irexec is started do the following command.
# ps -A | grep irexec
- Now you need to add to your lirc file so that irw commands irexec to execute the script. Edit ~/.mythtv/lircrc so that it contains this
begin prog = irexec button = Red repeat = 3 config = start-script -composite end begin prog = irexec button = Blue repeat = 3 config = start-script end
Troubleshooting
To be determined
