Desktop Effects (the application of XGL and Compviz technologies) are a relatively new addition to Linux, and as such are in the initial stages of integration with the rest of the desktop. The purpose of this page is to house information about using Desktop Effects, and to discuss their potential application.
There are many options available for the person who wants to customize her Desktop Effects; some of these options are (relatively) easy to find in the Desktop Effects (gnome-xgl-settings) capplet, while some are only changeable from the Configuration Editor (gconf-editor). Thanks to Dan W, we have the following descriptive list of the options available through gconf.
the cube looks as though there’s a light shining on it from somewhere. If unset, it’s evenly lit.
/apps/compiz/plugins/cube/screen0/options/skydome_animated: if set, the skydome_image rotates opposite the cube as the cube rotates. So if you set the skydome_image to a picture of sky with clouds, or a starscape, then when you rotate the cube, the effect is as though the cube is staying in place and you are moving around it (and so you see a different portion of the sky behind each cube face). This is one of the blingiest options that we don’t have a UI for configuring yet. :)
/apps/compiz/plugins/move/screen0/options/snapoff_maximized: If set (the default), you can unmaximize windows by dragging down on the titlebar, to snap them away from the edge. If you have wobbly windows on, this behaves in a physically plausible manner; if you don’t, it just suddenly shifts from maximized to not.
/apps/compiz/plugins/scale/screen0/options/: options for the scale plugin, aka “the plugin formerly known as exposé”. You can tweak things like how dark/transparent various parts of it are, whether or not to use icon overlays, etc.
/apps/compiz/plugins/wobbly/screen0/options/_window_types: lets you enable wobble-on-focus, wobble-on-X-grab (ie, something grabs the mouse, preventing you from interacting with other apps),
wobble-on-map (map == when the window first appears) and wobble-on-move for individual window types.
/apps/compiz/plugins/wobbly/screen0/options/friction,grid_resolution, min_grid_size, spring_k: lets you change exactly how wobbly the windows are (I have no idea what the numbers mean. Just play around with them...)
