Python script hangs on ubuntu server using selenium firefox driver -

Python script hangs on ubuntu server using selenium firefox driver -

i'm trying take screenshots of webpages. opted selenium , firefox. i'm using xvfb , setting environment variable display.

the script works fine without xvfb on os x desktop. on server script hangs after webdriver.firefox() issued if python script no longer executing. no exception ever raised , firefox still active in process list.

setup:

sudo xvfb :10 -ac export display=:10

test.py

from selenium import webdriver print 'start' firefox = webdriver.firefox() print 'hello?' firefox.quit() print 'done!'

output:

start cursor winks tauntingly

i had same problem chrome. tried phantomjs flash fork, successful did not capture flash content.

starting independently firefox gives
