To run something from the other user in a terminal, switch to this user first:

sudo su - render

Then enter the command.

my assumption is, alsa lib is related to sound..if so... output devices list seems like...

i wish i knew how to set card1 as default output device.

OR

Q. is there a way to tell afanacy to use default user account (user) rather then user it created (render).?

thanks for your support / time. have a good day. regards,haseeb

Hi!

If your render engine needs display, how are you going to render as service (w/o display)?
- Ask on Blender forums, how it happens, how to avoid it.
- As a temporary solution, try to run afrender not as a service, but as a common program with display. Open terminal from a GUI user session, stop afrender service:

Code: Select all

sudo systemctl stop afrender

.
Go to cgru root folder and start afrender not as a service:

Code: Select all

cd cgru
source ./setup.sh
afrender

Read SystemD manuals to find different ways to setup the user to start systemd service by.
There are lot of SystemD documentation over internet.
