I have just enabled desktop effects on Gnome in F7. ( Well, prior to that, I have to add that Composite extension and add the line to omit xfree86-dga in xorg.conf ... then install the various berly packages ). I can see the wobbling effects on the windows in Gnome ... but I could not figure out how to actually have the cube workspaces ( I have both wobbling effects and cube workspace checkboxes enabled ). Do I need to do something else ? If I use KDE instead, I don't get the wobbling effects, but I do recognise that menus are somewhat animated ( drawn from small, then bigger and bigger until it reaches its normal size ), or a sliding effect. All of this is actual fast, so perhaps the only reason I noticed it was because I was conscious that I enabled desktop effects in Gnome. Looking at KDE Control Center, there is now a Beryl option under "Appearance and Themes". This option shows Opacity and Shadows. Under the "Style" option in Control Panel and then the "Effects" toolbar, I also see "Enable GUI Effects" which is checked, and they all have the "Animate" option selected, except for the "Menu tear-off handles" which has "Application Level". So my questions are: 1) How do I get cube workspaces in Gnome ? ( The option is checked in "Desktop Effects" ). 2) How do I have wobbling windows in KDE ? 3) How do I have cube workspaces in KDE ? What other "effects" could I do ?
