From your bug report I see that you have a very complex multi-monitor=20= =20 setup=20on your client running X2Go Client. The Xinerama implementation in nx-libs has been reworked tremendously. Could you please try to install a test server running nx-libs 3.6.x? The nx-libs 3.6.x can be obtained from deb http://packages.arctica-project.org/ubuntu-nightly trusty main You have to add "+xinerama" to the X2GO_NXAGENT_DEFAULT_OPTIONS in=20=20 /etc/x2go/x2goagent.options.=20Currently the Xinerama switch in X2Go=20=20 Client=20is ignored, but you can test Xinerama with nx-libs 3.6.x. Also on resumed sessions, the Xinerama extension will not be present.=20=20 That=20is also work to be done in X2Go Server. (Please ignore it for=20=20 now...).
