[mythtv-users] mythtv 0.20-svn + pvr-350 + x-out on ubuntu feisty

[Matt Price]

hi folks,

for over a year i've been running mythtv 0.18 with few problems under
ubuntu breezy, using a cheap old dell and a hauppauge pvr-350
capture/tv-out card.  but becausee so many of my friends and family want
me to 'tape a show' for them, i decided to try and take advantage ofhte
new myth-archive plugin which is standard with mythtv-0.20, and is
included since edgy.  since the ivtv drivers are included by default
with feisty, i decided to upgrade all the way to feisty. 

since my family hates it when i break things, i cloned the root
partition using rsync and then upgraded in stages
breezy=dapper-edgy-feisty.  this seemed to go well, i rebooted into the
new system and... things MOStLY worked.  mythbackend runs, but i can't
get X to display on the pvr-350 tv-out anymore.  i have redownloaded the
x-driver and firmware for ivtv, and the modules load fine; moreover
there aren't any error messages in /var/log/Xorg.0.log.   ps aux also
reports that mythfrontend is running under the minimal window manager
evilwm, which is all as it should be; but in actuality the x session is
not being displayed on any screen, neither the monitor plugged in to my
vga out nor on the tv-screen through the pvr-350 (which is where i want
it to go).  i'm not really sure exactly how to debug this further,
except to give my xorg.conf and my .xsession and ask for help. 

so here's /home/mythtv/.xsession, which autoloads when gdm starts up
(though i tend to think this can't be the problem, as i never see the
gdm screen on any display, even if i kill mythfrontend and thus bring
the mythtv session to a close) :
-------
#!/bin/bash
# Merge X resources from ~/.Xdefaults
[ -f $HOME/.Xdefaults ] && xrdb $HOME/.Xdefaults

# Set the background and root cursor shape
xsetroot -solid \#400040


# Start evilwm - snap to borders within 10 pixels
/usr/bin/evilwm -snap 6 -bw 0 &
wmpid=$!

/usr/X11R6/bin/xset s noblank &
/usr/X11R6/bin/xset s off &
/usr/X11R6/bin/xset -dpms &

exec mythfrontend -l ~/.mythfrontend.log


# when the window manager exits, allow the X server to be torn down
wait $wmpid

-------------------------------------

and here's the whole of /etc/X11/xorg.conf (doubtless some of it is
superfluous, sorry...
# /etc/X11/xorg.conf (xorg X Window System server configuration file)

I don't see anything obvious in /var/log/Xorg.0.log
or /var/log/mythtv/mythbackend.log .  if anyone has any hints as to
where my x-session has gone, i would be VERY grateful!

thanks,

matt
