So you should checkout difference between computers that use GPU and that use CPU.
But it seems that Blender needs a GUI session to use GPU (very pity).
May be all your ms windows afrenders runs within a GUI session?
And some Linuxes runs afrenders from init.d or systemd daemon with no GUI?
If so, you should write to Blender developers, other soft that uses GPU do not need a GUI session.
- what we should do with a cloud rendering? cloud with a GUI session is much more complex.

Sory for my quite poor english.

It looks like its not blender itself.

This is rendering on CGRU. (look at cpu and gpu utilisation)

And this is same command copied to terminal- so rendering without gui. Also i heard that blender works on AWS cloud withoud problem.

This is all done on one computer. So it seems that its cgru issue not blender itself...

"And this is same command copied to terminal- so rendering without gui"
- Terminal launched from GUI have a GUI. I see you screenshot - that terminal with a GUI.
In that terminal type:

Code: Select all

cd /opt/cgru
source ./setup.sh
afrender
- So that afrender client will be with GUI.
And check how it works.

At first you should ask:
- Can I render using GPU running Blender command line with no display? If I can, how to do it?
(may be we are doing something wrong)
