I disabled everything. Right now I have it just go to a screensaver...  
I disabled all power management with gnome-power-preferences. When it  
goes to the screensaver, mythfrontend freezes. My remote wont stop the  
screensaver. If I wiggle the mouse the screensaver stops, and  
mythfrontend is completely unresponsive. Nothing in the logs. I need  
to remotely kill mythfrontend, and then restart it.

This is driving me NUTS. I running mythbuntu 8.10 w/ the weekly fixes  
build. The past two updates seem to have made this worse. It use to  
happen maybe 30-40% of the time, but now it freezes 100% of the time  
if I let it sit idle for a while. I have no other problems.

What could mythfrontend be doing while idle that would cause it to  
lock up, and NOT leave anything in the logs? I dont know how lirc  
works, but I find it strange I can wake up the screensaver with the  
mouse but not the remote. But since I believe lirc only influences  
mythfrontend, with mythfrontend hung, I guess it makes sense. I'm  
pulling out my hair over here, because every time I sit down to watch  
TV it turns into a big ordeal.
