scenic

I was running sudo pbuilder build scenic_0.6.3-1.dsc which builds it without X11.

The DISPLAY env var is present. We should not onyl check for its presence, but also test if can open the display with gtk, prior to run this test.

At least, please print an error message. Avoid using assert like that, please.

Which jack-info executable is it running? What if there is one that is installed?
