Hi guys,
judging from this user feedback, maybe we should change our terminology? "Detach" (German: "Trennen") seems to be less misleading than "Suspend" (German: "Anhalten"). At least one of the closed-source, commercial players in the remote desktop field uses "Trennen" in its German client software, too.

X2go is generally working well as a replacement (thanks guys!), however one complaint that I'm getting from users is that x2go suspends sessions on disconnect. Some users have graphical tools that they are kicking off to run long tasks and want to disconnect, leaving the task to complete (for example, over night) without needing the session to be maintained. This was the default behaviour in neatx and hence the behaviour that the users have come to expect (sessions wouldn't suspend on disconnect). Is there any mechanism built into x2go to achieve this?
Are you sure your users actually tried that out and aren't just mislead by the expression "suspend"? In fact, it is more like "detach". You detach the X2Go session, and the virtual screen on the server remains running, so you can re-attach at any time.
I'd had a few guys independently raise this with me and hadn't actually tested it (it didn't seem unlikely and the "suspend" terminology made it seem plausible).
A quick test running a loop in a terminal kinda proved that they were wrong...
For anyone reading this in the archive, try:
i=0; while [ 1 ]; do echo Count $i; let i=$i+1; sleep 1; done
Leave running and disconnect, log back in after a while, you'll see the count has increased proportionally with the time that's past. (Or ssh in separately and watch the PID of the sleep command increment).
Sorry for the noise.
Martyn
I think there was a piece of code that would let you renice sessions that were in a detached state, so they take up less CPU, but I'm not sure if that made it to a stable release yet. Mike#1 might know more.
A full suspend, comparable to a laptop suspend/hibernate, is not something X2Go does.
