[mythtv-users] Tv out on Pvr350 used to work, but I broke it?

This is a long story, so I'll try to keep short. I had separate X
servers running on my pc monitor and the Pvr350's tvout port (to
connected tv). The GUI image was too large for the TV, so I tried to
correct it. Most attempts didn't work, but they didn't hurt anything.
After trying this suggestion:
.....
Edit /etc/X11/gdm/gdm.conf and in the [server-Standard] section, change:
command=/usr/X11R6/bin/X -audit 0
to
command=/usr/X11R6/bin/X -dpi 100 -audit 0
......
From:
http://www.gossamer-threads.com/lists/mythtv/users/109220?search_string=gdm.conf;#109220
, the pc locked up and had to be hard reset. After rebooting, xorg.conf
and gdm.conf were both trashed (garbage throughout). I got xorg.conf
restored from a backup, and got a clean (??) copy of gdm.conf from
another pc. Now, I can run either server, but not both at the same
time. Here are some symptoms:
- Run X on pc monitor only, works and mythtv plays on pvr350 tvout port
- Run X on pvr350 tvout, works and mythtv plays on tvout port
- Run both from a clean boot, computer freezes (needs hard reset)
But, if I do this, both work once.
- Run X on pc monitor only
- Play live tv on mythtv on on pvr350 tvout
- Logout of X, turn both servers back on, startx again
- X runs on both, but:
- at startup the tv speaker buzzes
- Tv shows the X session for a couple of seconds, goes blank
- Move mouse over to Tv display, and X session is repainted wherever
the mouse is moved.
- Play live tv on pvr350 tvout, it works
- Logout of X
- Run X again, computer freezes
Any suggestions on what to try? Thanks,
Don
PS - Here's part of the xorg.conf file. I turn the monitor and pvr350
on / off by commenting out the appropriate line(s) in the server layout
section.
