I dont know if that could help you but it seems to be a VT-Switch related
problem. When you hit Ctrl-Alt-FX, a signal (SIGUSR1) is sent to X.org. This
signal raise a flag that is handled by xf86Wakeup then xf86VTSwitch. This
functions disable IO and framebuffer access for all screens. Then, an ioctl is
sent to switch to cli.
I'm not familiar with multiseat, but this situation seems normal if your two
seats share the same X instance. If not, it is a bit weird that the second X
instance got notified.

I think that -sharevts is used to allows multiple X instances to share the same
/dev/ttyx but i may be wrong or it can have other uses.

Hello,
Thanks for the replay,
I'm running X for each seat, meaning that any Ctrl-Alt-FX on a seat should not
be passed to the other seat.
in my case, the signal is passed only to the other seat, not even to the origin
seat.
why would multiple X instances to share the same /dev/ttyx? what is the gain in
that?
