[X2Go-User] Suspending sessions causes performance slowing down

[h i]

Hello,

We've been using x2go for a few months. Recent converts from using the old freenx nomachine 3.5.

We installed x2goserver on Ubuntu mate 18.04 and have several users connecting through x2goclient 4.1.2.2

I have a question regarding suspended sessions with x2go. When we suspended an open session, we noticed the session stopped running. After resuming the session the next day, the process resumed executing. Thought this was strange and rebooted the server.

Ran a few tests and noticed performance slows after suspending a session.

Here is output from gxlgears. You can see the FPS decreases when the session suspends. The FPS returns back to normal (633 at the bottom), upon resuming the session.

I searched online and discovered you can change the /etc/x2go/x2goagent.options to X2GO_NXOPTIONS="sleep=0". When doing this, now the performance increases considerably after suspending the session (middle portion of the output).

Is there a way to suspend an x2go session, and have no decrease or increase in performance? Is there some setting we can change to keep things running as is while session is suspended?

Thanks in advance.
