Since KNIME is a graphical application it needs an X server. Please check if the DISPLAY variable is set to a valid value.
It is set and now got it only working for root.
How do I get it working for a nonroot user.
Thanks
ALso can you execute a workflow in batchmode with out knime having to launch its display?
knime -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION
-workflowDir="workspace/<your_workflow>"
When I login as root and launch the command it works only as root and has to launch the knime analytics to process the workflow. Is there a way for it to process the workflow and not have to launch the analytics display?
If you cannot start KNIME as normal user from a shell then something is wrong with your system configuration. KNIME is just like any other program with a GUI. I guess you also cannot launch any other GUI program. I suggest you fix your system first before you continue.
The batch mode of KNIME does not need a GUI and works without an X connection.
Yes it worked thank you so much.
I am facing the similar issue. Not sure if I am setting the display variable properly. Please advise with example.
I am facing the similar issue. Please advise how did you setup the display variable to resolve this.
How to check if the DISPLAY variable is set to a valid value?
Hi @pkamenga , you can just print the variable:
echo $DISPLAY
Hi Bruno,
I have run the command. nothing displayed. screenshot below.
Hi @pkamenga , it looks like you don’t have any X connection. Are you connected remotely to your Linux Box?
Also, are you in an Anaconda environment? What is that base) in your prompt from/for?
Hi @bruno29a ,
Yes I’m connected remotely to our Linux Box. Yes I’m in Anaconda environment. below base.

Hello @pkamenga,
if this is related to KNIME Server I suggest to open up a new topic for it.
