Hi I tried to run example in README on Archlinux with Python 3.5

Python 3.5.2 |Anaconda 4.2.0 (64-bit)| (default, Jul  2 2016, 17:53:06) 
Type "copyright", "credits" or "license" for more information.

IPython 5.1.0 -- An enhanced Interactive Python.

In [1]: import gym
   ...: import universe  # register the universe environments
   ...: 
   ...: env = gym.make('flashgames.DuskDrive-v0')
   ...: env.configure(remotes=1)  # automatically creates a local docker container
   ...: observation_n = env.reset()
   ...: 
   ...: while True:
   ...:   action_n = [[('KeyEvent', 'ArrowUp', True)] for ob in observation_n]  # your agent here
   ...:   observation_n, reward_n, done_n, info = env.step(action_n)
   ...:   env.render()
   ...: 

but it's show below error

Any suggestions

Try it under regular (not Iron) Python, with the program in a file instead of typing interactively. Iron Python does something strange with X11 and threads.

@tlbtlbtlb Thanks, I just tried without regular iPython, and also get same error, (I'm using Xmonad as WM, does that matter?)

Does your system run OpenGL? If you run glxgears, do you see gears spinning on screen? If not, that's the problem.

If you drop the call to env.render(), you can watch the environment run by pointing your browser to http://localhost:15900 instead.

seems it's a issue of Xmonad, I switch to Openbox and it works for me, Thanks @tlbtlbtlb
