Drivers call xf86InstallSIGIOHandler() for their fd on DEVICE_ON. That function does not actually enable the signal if it was blocked to begin with. As a result, if one vt-switches away from the server (SIGIO is blocked) and then triggers a server regeneration, the signal remains blocked and input devices are dead. Avoid this by always unblocking SIGIO when we start the server.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
