Real headless rendering

[Arthur151]

Awesome project! The rendering works great on the desktop. But on the remote server, we may need a real headless rendering to avoid the error like: (standalone) XOpenDistplay: cannot open display

The following should fix this problem (it essentially fakes the existence of a display device):

export DISPLAY=:0.0
Xvfb :0 -screen 0 640x480x24 &

This is usually sufficient for us. Did you have any other strategies for "real headless rendering" in mind? Would be curious to hear!

Closing this since this hasn't been active in a while. Feel free to re-open it again in the future if required.

Hi! Thanks for providing this solution for headless rendering. But I meet an error message like this:

_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running
(EE) 
Fatal server error:
(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE) 

I try to change the display id like this:

Xvfb :1 -screen 0 640x480x24 &
export DISPLAY=:1.0

Then I meet this problem:

_XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be created.

Would you like to help me with this? Do you have any other strategy for headless rendering?

This seems to be a configuration issue with your system's X server, so unfortunately I cannot offer too much help, as this highly depends on your setup (e.g. searching for your last error message suggests that Xvfb might want root access).
