Pat Deegan commented on CB-11870:

An interesting development, and possible clue to the nature of the issue:  I've 
found a way to get something to display--when you drag content (images and 
sometimes divs) it shows up momentarily.

There's a short demo of how to reproduce and of the effect at

> 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)
