You shouldn't need to create that script, as it's already present in 
/usr/bin/napari :-)

I think it's related to python-vispy. I prepared and uploaded a package 
for a new upstream version of python-vispy (0.13.0-1) and tightened the 
dependency and build-dependency of napari on it, and now it does launch 
a GUI. The new napari (0.5.0~a1-4) is uploaded to unstable too.
