[mythtv-users] nvidia driver woes

[John Finlay]

I used to have an old analog tv on one of my myth frontends which drove 
it via the nvidia driver tv out (svideo). I upgraded to a new flat panel 
but I can't get x to start on the system. I finally gave up and did a 
new install of mythbuntu but as soon as I did the updates the nvidia 304 
driver was installed and now X won't start again. It almost seems as if 
the nvidia card is stuck on tv out as it's primary connection. The xorg 
log errors are:

If I switch to an alternate tty and manually startx all seems to go 
correctly. Before using this same system with the analog tv I used it 
with the same flat panel without a problem. I speculate that when I 
started to use tv out something was changed that now prevents proper use 
with tv out disabled. Is that possible?
