Hi,

Is there hands-on instructions how to downgrade to Saimaa in Ubuntu (4.13.0-)?
X2Go sessions terminate in random way.

Yes.

This is what i just did more or less following Stefans advice.


sudo mv x2go-stable-trusty.list x2go-stable-trusty.list.not
sudo add-apt-repository ppa:x2go/saimaa
sudo apt-get update

sudo apt-get remove libnx-x11-6:i386 nxagent nxproxy nx-x11-common x2goclient x2goserver* libx2go-log-perl libx2go-server-db-perl libx2go-server-perl libxcomp3:i386 libxcompshad3:i386
sudo apt-get install x2goserver x2goserver-xsession

This leaves me with

 dpkg -l | egrep "(x2go|nx)" | sort

Somehow i believe this is system related to my box rather than packaging, but i somehow can't put my finger on it.
Anybody see anything i overlooked?
