Thanks, I'll look into it. looks like it's missing a merge from master,
since don't think I ever touched this file.

ok, now this sounds a bit weird. xinit choosing the right binary?

this is intentional behaviour. unless a user explicitly wants to have
two cursors, they shouldn't even notice mpx is there.


in your case, you will need the xinput tool to create a new master.
compile the mpx branch from
git://anongit.freedesktop.org/git/xorg/app/xinput

and then run

$> xinput --create-master foobar
this will create a "foobar pointer" and a "foobar keyboard" device and a
new cursor+kbd focus.
$> xinput --reattach 5 6
this will reattach device 5 to device 6. modify appropriately to attach
your mouse to foobar pointer.
