[winswitch] error on build

[Michael Durkin]

ok .. this did work ....
at first i thought it was not ... but after (finally) looking at the log i
seen that Xvfb was causing an error ... it was not installed (iv done this
mistake more than once in the last few years)...

It might be handy to add installing Xvfb to the debian/ubuntu build section
