Aim : Use 1 computer for two tasks : a) Desktop for GF to use as a regular linux machine (web browsing, photos, etc)b) Completely independent MythTV set-up, with the output going to the TV.
Also, the set-up has to be turn-key, with both sessions logging in automatically (goodbye gdm).
There’s a lot going on for this [...]
