> Key: CB-11870
> URL: https://issues.apache.org/jira/browse/CB-11870
> Project: Apache Cordova
> Issue Type: Bug
> Components: Ubuntu
> Affects Versions: 6.3.1
> Environment: Node version: v6.6.0
> Cordova version: 6.3.1
> Ubuntu: 16.04
> Compiz/Unity plugins: 'core', 'composite', 'opengl', 'regex', 'resize', 'commands', 'animation', 'snap', 'wall', 'place', 'compiztoolbox', 'imgpng', 'mousepoll', 'grid', 'unitymtgrabhandles', 'vpswitch', 'copytex', 'move', 'workarounds', 'session', 'fade', 'scale', 'expo', 'ezoom', 'unityshell'
> Reporter: Pat Deegan
> Assignee: Maxim Ermilov
> Labels: blackwindow, ubuntu
>
> On a fresh install of both Ubuntu (16.04) and node/cordova, doing a standard "hello world" create/build/run:
> $ cordova create hello com.example.hello HelloWorld
> $ cd hello/
> $ cordova platforms add ubuntu
> $ cordova build ubuntu
> $ cordova run ubuntu
> yields a black screen. Checking debug console (using chromium) seems to show the program is running correctly.
> However, an strace of the process shows that the program starts up and then goes into a tight loop of polling on the /tmp/.X11-unix/X0 which gives a series of EAGAIN (resource unavailable) messages, e.g.
> recvmsg(6, 0x7ffe56802b20, 0) = -1 EAGAIN (Resource temporarily unavailable)
> recvmsg(6, 0x7ffe56802b20, 0) = -1 EAGAIN (Resource temporarily unavailable)
> Quick demo of entire process and result uploaded to
