fix startup with Xephyr #414

Closed Piskvor closed 3 years ago

Piskvor commented 3 years ago

When Xephyr (or another X server) is provided outside of the container, do not try to start Xvfb on its DISPLAY - this will fail. Instead, set the display number.

(This bug seems to be caused by an omission - "we always need Xvfb [except when XE_DISP_NUM is passed in]")
