Hello Eric,

Hi all,

Is there a way to configure a framebuffer console on a specific display
on a machine with multiple displays?


Have you looked at https://www.kernel.org/doc/Documentation/fb/fbcon.txt ?

There is a sysfb interface to bind / unbind fbdev devices to fbcon's VT
(/sys/class/vtconsole/vtcon1/bind) and also kernel command line parameter
to choose which fbdev driver is mapped to which VT console (fbcon=map:n).


I have seen this, but it's not clear how we can use this. In our case, we have a single driver for two displays.

I hope to get a device on my desk this week to test it out.
