It's me again. I did a quick search on the list, and noticed there
aren't any recent posts regarding this. I'm not sure if it's a Myth
issue or ivtv.
If I run Myth on screen 0 (VGA monitor DISPLAY=:0.0) and output the TV
via the PVR350 TVOUT (screen 1) to TV, then all seems to fine.
If I run Myth on screen 1 (TVOUT on PVR350 DISPLAY=:0.1) then if I bring
up EPG and navigate, the sytem hard locks.
The only weird things I see in syslog when I load all the modules:
Nov 7 13:29:12 pvr1 insmod:
/lib/modules/2.4.21-0.25mdk/kernel/drivers/media/video/bttv.o.gz:
init_module: No such device
Nov 7 13:29:12 pvr1 insmod: Hint: insmod errors can be caused by
incorrect module parameters, including invalid IO or IRQ
parameters. You may find more information in syslog or the output
from dmesg
Nov 7 13:29:12 pvr1 modprobe: modprobe: insmod bttv failed
Nov 7 13:29:12 pvr1 modprobe: modprobe: Can't locate module rivatv
...
Nov 7 13:29:12 pvr1 kernel: ivtv-fb: warning: cannot reserve video
memory at 0xdd510000
I start this system in what I'll call a "RAW" state. The only thing
that loads is X. I have two scripts that I use to load/unload all the
modules and daemons needed by myth. Then I open separate terms for
mythbackend -v AND mythfrontend -v. The backend runs as root, and the
frontend runs as user mythtv:
[root [at] pvr root]# cat livtv.scr
#!/bin/bash
# Source function library.
. /etc/rc.d/init.d/functions
modprobe ivtv
modprobe ivtv-fb
# update perms
chmod 660 /dev/v4l/*
chmod 660 /dev/fb/*
chmod 660 /dev/sound/*
chgrp mythtv /dev/v4l/*
chgrp mythtv /dev/fb/*
/usr/local/sbin/lircd
/etc/rc.d/init.d/dm restart
[root [at] pvr root]# cat uivtv.scr
#!/bin/bash
# Source function library.
. /etc/rc.d/init.d/functions
/etc/rc.d/init.d/dm stop
killproc lircd
