Window() just freezes (in a docker)

[kforner]

Hi,

In a docker with remote x11, when I run:

using Blink
w = Window()

an empty window appears on my screen. But the julia REPL seems to be waiting, it does not print the prompt so that I can not type any further command.

If I close the window (with the cross), nothing happens.

If I type CTRL+C in the console, I get:

^CERROR: Unexpected end of input

I'm not entirely sure what In a docker with remote x11 means, but the main issue with Docker is that it's not usually running an X11 server. Does it work if you run with xvfb-run?

[kforner]

docker with remote x11

means that you use the local host X11 server by binding the x11 socker inside the container.
With this all usual x11 applications work (xeyes, evince, firefox, eclipse...).

Does it work if you run with xvfb-run?

I did not try, but here the point is to see the window
