Screen-specific privates areas are only allocated for objects related to the target screen; objects allocated for other screens will not have the private space reserved. This saves memory in these objects while also allowing hot-plug screens to have additional private allocation space beyond what the core screens are using. Drivers are encouraged to switch to this mechanism as it will reduce memory usage in multi-GPU environments, but it is only required for drivers which will be loaded after the server starts, like modesetting. Objects providing screen-specific privates *must* be managed by the screen-specific private API when allocating or initializing privates so that the per-screen area can be initialized properly. The objects which support screen-specific privates are: Windows Pixmaps GCs Pictures Extending this list to include Colormaps would be possible, but require slightly more work as the default colormap is created before all colormap privates are allocated during server startup, and hence gets a bunch of special treatment. Of particular note, glyphs are *not* capable of supporting screen-specific privates as they are global objects, not allocated on a screen-specific basis, and so each driver must be able to see their privates within the glyph.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
