[mythtv-users] Mythfrontend segfaults on load

Sun Nov 19 04:56:56 UTC 2006

I had yum updated to kernel 2.6.18-1.2849.fc6 and also got the required 
ivtv, nvidia lirc packages with the necessary kernel modules, so when I 
rebooted a couple of days ago, I was running kernel 2.6.18-1.2849.fc6. 

When I tried to start mythfrontend, nothing happened.  This is on my :0 
display (monitor with nvidia card).  Further exploration revealed that 
the frontend was dying very shortly after figuring out what painter I 
had selected.  The log in verbose mode gives the following:

And that's it -- after that, the front end segfaults.

The frontend that runs in the vnc window runs correctly and the remote 
even works with it.  I did a -v all with it and I've attached the log.  
(The frontend does a query or two doesn't it!)

Most notably, the vnc session hasn't got some of the bells and whistles 
of the actual front end such as GLX and RANDR.  Hopefully somebody can 
tell what's gone wrong from looking at all this.

Also, I am still wondering why my PVR-350 playback takes 50% cpu usage.  
That is a development that I think dates back to 0.20, but it also 
happened around the time I upgraded to FC6.

About that, here's the bit of the messages pertaining to the ivtv 
drivers loading.
