[X2Go-User] Turn off ALL clipborad interaction -- even PRIMARY (middle mouse clicking activities)?

Hi!

I really need to "sandbox" the user as much as possible.

I managed to rewrite the x2go client so the clipboard sharing is "none" whatever they select.

But is it also possible to turn off the classic X (PRIMARY) cut and paste-model?

Ideally I want to keep it working "inside" the g2go-login, but I can live with a way to completely turn it off.

So what I whant to achive is this:

1. No selection with mouse INSIDE the x2go-session should be middle-button-pasted outside the x2go-session
2. No middle middle-button-paste inside the x2go-session should "grab" information from the outside system.
3. All this must be activated on the server side -- but there it can be rather hard core fiddling...

Any ideas?
