Problems with interactive Matlab app window

Jeff, thank you very much for your engagement on this!

Those edits didn’t work for me, but I was able to get a fix.

It had to do with the dbus-launch command you first identified on our call, when reviewing the bc_desktop/template/desktops/xfce.sh script. I’m not sure what made me conclude it wasn’t working during the call, but it’s definitely working now.

Here’s my submit.sh.erb (the notable addition being eval $(dbus-launch --sh-syntax):

#!/usr/bin/env bash

# Clean the environment
module purge

# Set working directory to home directory
cd "${HOME}"

# Launch Xfce Window Manager and Panel
#

(
  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
  eval $(dbus-launch --sh-syntax)
  xfwm4 --compositor=off --sm-client-disable
  xsetroot -solid "#D3D3D3"
  xfsettingsd --daemon --sm-client-disable
  xfce4-panel --sm-client-disable
) &

#
# Start MATLAB
#

# Load the required environment
module load matlab

# Launch MATLAB
module list
set -x
matlab -desktop

I’m still a little hazy on the full picture, but the result that the Xfce components now have a dbus session interface running in the slurmd cgroup, rather than trying to use the short-lived connection in the user cgroup (XDG_RUNTIME_DIR). And the window control features work as expected!
