[Linux-fbdev-users] How to determine the console attached to a given fbdev

[Sean D'E. <se...@de...>]

I have implemented vt switching in my program, I can set up the program
to recieve signals if the vt it is attached to is aquired or
released using linux-kbd ioctls.

This would be enough if I did not have two monitors and two framebuffer
devices!  I want my program to be able to update if it is still the most
recently active vt on it's fbdev.

Right now I continuously poll ioctl on CON2FB while I do not have the
active vt, and supply the active vt number which I get from another ioctl.
If the resulting framebuffer matches mine, I know I need to stop drawing.

This is not a good solution, sometimes I need to refresh the display when
switching because of this.

Would anything need to be implemented in kernel space to allow for this? 


Thanks
