[mythtv-users] System started hanging after boot when configured to use the TV for display

[Jeff]

I'm not quite sure what I did that caused this to start happening but at
some point my MythDora 4 box rebooted and ended up at a blank screen. There
isn't anyway to get into it at this point (telnet and VNC servers don't
respond). The boot process seems to have completed. Sometimes you get a
glimpse of the desktop before it hangs, sometimes not. I'm pretty sure it
had been working properly and started misbehaving all of a sudden, but that
doesn't seem very likely :)

This is using a GeForce4 MX 440 and NVIDIA dlloader X Driver 1.0-9639 Mon
Apr 16 20:21:54 PDT 2007

I believe mythdora installs a different Nvidia driver version but I had to
get this one to get support for the UseDisplayDevice because I couldn't get
X to use my TV as output even if no other monitor was attached.

At the moment if I remove
    Option "UseDisplayDevice" "TV"

then the system will boot and behave normally (on the CRT). If I add this
back then it boots but hangs.

This is the end of the X log from the bad boot:

Without the UseDisplayDevice (good boot) I get:
