I've used x2go on linux (Fedora) for years and never experienced this before. I just setup a new workstation.

When I suspend a session, the running processes started by it seem to sleep. A bit of googling suggested I

need to edit /etc/x2go/x2goagent.options setting:

X2GO_NXOPTIONS="sleep=0"

I hope this helps: it hasn't yet. Will this only take effect after I terminate the current session and start a new one?

Those who don't understand recursion are doomed to repeat it
