On RHEL 10 starting a single application may be not possible
On Red Hat 10 single applications fail to start in NoMachine custom sessions.
A possible workaround is to specify to launch the application through D-Bus.
To do that add 'dbus-run-session' before the command to start the application in a custom session.
For example, to launch the default terminal Ptyxis, command is:
dbus-run-session ptyxis --new-window
Note that this affects also the DefaultConsole key in node.cfg.
