Question / Help unable to run on headless machine

[Marco G.]

I installed obs and openGL on an headless server on AWS and using an ssh tunnel to log in and to use a remote display.

ubuntu@ip-172-30-0-159:~$ echo $DISPLAY
localhost:10.0

Staring obs bring up a pop-up erroe window with the message "Failed to initialize video: Unspecified error" and the following on the terminal:

ubuntu@ip-172-30-0-159:~$ obs

The file /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so does exist on my system (64-bit Ubuntu 15.04).

OpenGL seems also to be installed properly as I can run and see the display on my local machine for glxgears, although there are some errors:

OBS requires a GPU to render on. An emulated adapter / remote display is unlikely to work.

I can get a AWS server with a GPU. Would then obs run headless?

Thanks,

Probably not very well. But with AWS I suppose you can test it and only pay for an hour of time.
