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.
