    5858The {{{LD_PRELOAD}}} trick only tells the application how to query for Xinerama screen information, it does not and cannot tell the application when it should refresh this data. Unfortunately, this means that many applications will only query this data once and cache the results.

    60 This means that you MUST connect your client (which will cause the Xpra server to generate a suitable fake xinerama configuration file) BEFORE starting the X11 client application that will use fake Xinerama.. Alternatively, you could start your application separately specifying {{{LD_PRELOAD}}} yourself, but then you either need to somehow pre-define the configuration file before the client connects or ensure that the application will only query Xinerama after Xpra/you have populated it.
     60Xpra solves this by always re-setting the display dimensions using [http://en.wikipedia.org/wiki/RandR RandR], which is usually enough to make the application re-query Xinerama.
