This solves a race if we are trying to dynamically power off secondary GPUs. Its not the greatest fix ever but it probably as good as we can do for now. The GPU probing causes the devices to be powered up, then when we scan the PCI bus we get the correct information from the kernel, rather than a bunch of 0xff due to the device being powered off. drop gratuitous '&'.

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.
