Tx2 has two HDMI outputs, one is HDMI-0 and the other is HDMI-1. Then the default HDMI of the system is HDMI-0. How to make the system output to HDMI-1 by default?
What is your definition of “default monitor”?
System default image display output.In TX2, the default display output is HDMI-0. Now we want the system’s display output to be HDMI-1.How to configure to adjust the display output of the system to HDMI-1？
Your definition of default screen is the primary monitor from X11, right?
yes，primary monitor from X11
If you want to change the default output from X, please try
xrandr --output HDMI-1 --primary
did you resolve the problem that changing HDMI-0 to HDMI-1? i tryied ”xrandr --output HDMI-1 --primary”，it tells “warning: output HDMI-1 not found; ignoring”.
Do you have HDMI-1 in your xrandr list? If there is not, then it if of course not going to work…
Our platform base on tx2 with dual HDMI output. And we use fix edid code and set "use_fallback = true "in edid.c.
Does tx2 two HDMI support different resolution like HDMI0 1920x1080@60fps and HDMI1 1024x768@60fps according to edit edid code?
