It takes a bit of time for Xvfb to start, so you may need a "sleep"
after starting Xvfb before you can actually use it.

I've been using Xvfb on a number of machines for years. Most of these
machines run for extended periods between boots, so I just start Xvfb
manually after a restart. There is one (headless) machine where we have
to use TCPIP, e.g. DISPLAY=localhost:2 in place of just DISPLAY=:2.

You can query the Xvfb server using xdpyinfo.
