After upgrading to Ubuntu 18.04 LTS and after successfully installing the Displaylink driver, I find that NoMachine Workstation version 6.1 no longer is accessible; opening a terminal session yields error “could not acquire name on session bus”. Unfortunately I can no longer tell whether this problem begun after the OS upgrade or the Displaylink driver installation. Otherwise the installation appears to be in good health.
The Interweb has a few suggestions regarding the same error and other remoting tools such as VNC, such as the suggestion to “unset DBUS_SESSION_BUS_ADDRESS” to “~/.vnc/xstartup file after unset SESSION_MANAGER“. Obviously this is about VNC, not nomachine.
Does anyone know how this error can be avoided with NoMachine, or where I might try to apply a workaround similar to the one suggested for VNC?
