Hi, I’m having some problems with Matlab interactive app. Matlab does launch normally but window is very small and cannot be resized. I’m using xfce, have tried also Mate with same result. Desktop app works fine (fit to screen) but haven’t tried any other GUI apps yet. Any help would be appreciated.
My output.log file:

So I understand correctly, are you using a modified version of this app for your location:
If so, would it be possible to see the scritp.sh.erb you are using for the app?
What version of OOD are you using?
This would give me the best view of what is missing when the environment is setup and it sounds like the window manager is missing so knowing how the app is getting setup will help.
Yes, I’m using this version of the app. For script.sh.erb I am using a little modified template for XFCE use case
provided in your documentation. This is how it looks:
#
# Launch Xfce Window Manager and Panel
#
(
export SEND_256_COLORS_TO_REMOTE=1
# session.staged_root.join("config") refers to /.../bc_my_center_matlab/template/config
# which is copied at job start time to a session specifc directory.
# It will override without replacing any XFCE settings that the user
# already has.
export XDG_CONFIG_HOME="<%= session.staged_root.join("config") %>"
export XDG_DATA_HOME="<%= session.staged_root.join("share") %>"
export XDG_CACHE_HOME="$(mktemp -d)"
module restore
set -x
xfwm4 --compositor=off --daemon --sm-client-disable
xsetroot -solid "#D3D3D3"
xfsettingsd --sm-client-disable
xfce4-panel --sm-client-disable
) &
cd "$HOME"
#
# Start MATLAB
#
# Launch MATLAB
set -x
matlab -desktop # Launch MATLAB
One thing to do is make sure to include the module purge to ensure you are working in a clean environment for LMOD as the app builds. It looks like that is missing at the start.
The ERROR messages in the logs all suggest that there is nothing being loaded for those modules and so I guess I’d be curious if those modules are on the system. Can you put a module list at the end of the script.sh.erb to capture what modules are loaded in the output.log.
Is there a reason for removing the some of those LMOD commands overall?
Did you have the following line in mind?
module load xalt/latest <%= context.version %>
I am currently testing OOD on a testing system which has no modules available, but I have installed required packages on worker node and set up environment locally on that node for my user.
My logs on worker after starting Matlab if it is to any help:

Thanks for that information. Knowing there’s packages there and looking at the script I can’t see anything there that looks wrong.
Ok, so looking at the script things look fine knowing there’s packages there to use (also, you can remove all the module lines to get rid of those missing module errors in the logs).
Looking at the logs, this looks to be a problem of which display is being used. Notice this message in the first logs you posted:
So this is using display :1.
But then subsequent errors for xfsettingsd it is trying to use :0 and this is not where the window manager is running.
Now, why that is happening I’m trying to debug currently still, but that looks to be the problem.
This is the other error I’m looking at as it may be the main culprit and not the display:
