[mythtv-users] mythbuntu stops working for no reason

[Dan Hayes]

Ok, I just checked and the entire machine is not locking up.  Its just the
mythtv frontend that's freezing.  while its frozen, the caps lock key
toggles the light on the keyboard, and I can drop to a command prompt with
ctrl+alt+f1.  commands enter and run fine while the frontend is locked up
attempting to play live tv.
