[mythtv-users] Dual-Head and misplacement of mythfrontend

[DaveD]

Do you actually have two displays (two video cards) or just one display 
with two screens (one video card (GPU) with dual montior connections)?

You may need to specify the display in a variable before starting Myth.  
If you have two displays:
export DISPLAY=:1.0; mythfrontend  (change :1.0 to 0.0, as needed)
or if you have one display with two screens
export DISPLAY=:0.1; mythfrontend (change :0.1 to :0.0, as needed)

Hope this helps.
