Run exported app without display
Nov 27th, 2007, 8:28pm  
Hi, we have a processing app that renders a series of images.

I've exported it as a linux application, but when I run it it opens an X11 window and show the display while also rendering the images to disk.

I want to run this in a command line context on linux without having to show the display. How do I do this?

Short answer: I don't think you can.

Hm. Well, thanks to your link I at least got it to not pop open a X window while rendering by using the non-display render code posted there.

But on the mac when I do this it renders faster than real time, using 100% of the CPU. On Linux, it uses 1% or 2% of the CPU and takes much longer than real time. Is it still sending data over X11 even though a window is not showing up?

Hey, I got it to not take forever on a remote linux box. You still need X11 but I did

# apt-get install xvfb
# Xvfb :2 &
[1] 14401
# export DISPLAY=":2"
# ./runcode

This creates a virtual framebuffer so it doesn't have to send over all the data to your client.
