Anyway, having to install a WM in a TCE is not dumb stuff, it makes TCE acts much more like a real desktop than without it (and thus, easier to debug and a more uniform setup than with local fat client). The real problem was this was not part of the x2gothinclient-displaymanager install and so, you had to patch the installation by hand which is always risky.

It is NOT the xinerama code going nuts, the difference is happening somewhere else in nxagent. I will try to determine the cause tonight.
