Comment 26 for bug 1875025

I recently added two Ubuntu 20.04 servers to my existing Ubuntu machines in the lab, and started experiencing something similar to this reported bug.

the problem happens when I remotely connect my new servers using x2go, and leave the session idle over >5 min. The x2go remote desktop screen appears to be frozen, no screensaver or password prompt is shown. The cursor is shown as an I-beam shape. However if I resize the x2go window, the desktop resizes accordingly. The only way for me to reactivate this remote window is to ssh to the server and kill the xfce4-screensaver process "/usr/bin/xfce4-screensaver --no-daemon"

My xfce4 screensaver is set as a blank screen, locking the screen after 5 min idle.

Please let me know if there is a workaround for this. I do not want to disable screensaver because it also disables this setting on my other machines because they share the same home dir via nfs.
