You don't need to be root; any user can use synclient (which is why the
option is described as "insecure").

Try running "ipcs -m", it will list all shared memory segments on your
system.  I think the one used by synclient is this one:

0x00005d8b 0          root      777        360        1

The address will be different, but it's owned by root, readable and
writable by anyone, and is 360 bytes long.

You can also check if you have tmpfs mounted on /dev/shm (Ubuntu should
do that by default, but you never know...)
