$ scl enable devtoolset-6 bash
$ export PATH=`pwd`:$PATH
$ ./ds9 &
[1] 2064301
$ . /ssd/lsstsw/stack/loadLSST.bash 
Note: use devtoolset-6 in conjunction with this stack.
$ setup lsst_distrib

Now wait for ds9 to load, then run:

$ pytest $AFW_DIR/tests/test_ds9.py

You should see a bunch of activity in the ds9 window.

Next, you want to setup your own display_ds9 code:

$ cd display_ds9
$ setup -k -r .

Now you can jump into IPython and try using it:

$ ipython
>>> import lsst.afw.display.ds9 as ds9
>>> import lsst.afw.image as afwImage
>>> exposure = afwImage.ExposureF(100, 100) # blank 100 by 100 pixel image
>>> ds9.mtv(exposure) # display the image

But why is it called mtv? https://github.com/lsst/afw/blob/master/python/lsst/afw/display/interface.py#L425
