I have decided to try this desktop out once again, even though it is not to everyone`s taste. I have switched to The Mist metacity theme and the Raleigh GTK theme. Pop up dialog windows appear and disappear very quickly indeed and the desktop is quite responsive after all. The only gripe I have with this desktop is that a part of the desktop will crash and then the pulseaudio sound will not work anymore necessitating that you log out and then back in to fix it. But this hopefully, soon we will see this remedied, or else this will get very annoying fast. Alsa still works though, I do not understand why they do not just use that instead. pulseaudio is very good when you are using HDMI audio output for crystal clear sound.
Anyway, I am liking this Gnome 3 better than the Unity desktop, but they are fundamentally the same thing, with the same layout, only that Unity has the left dock visible all the time and Gnome 3 only shows it when you move the mouse over to the top-left of the desktop. Anyone who wants to install and use Gnome 3 will need to install the Gnome tweak tool to enable a little more customisation than the default installation will allow. I still prefer Gnome 2, but I just wanted to try Gnome 3 again. My very nice apocalyptic wallpaper makes that Gnome 3 screenshot even better.

[4walled.org] Some people have had issues with HDMI sound on Fedora 15, but it seems to work fine for me, if the Gnome 3 sound system would not crash on me regularly. I have found some cool Gnome 3 themes here: http://blogs.codecommunity.org/mindbending/gnome-3-themes/. These are looking very nice and I would check these out if you are using Gnome 3.
As shown in the screenshot below, I have discovered how to change the Gnome Shell themes using packages available in the standard Fedora repositories. Just install the gnome-shell-extension-user-theme package and some theme packages as well, then press Alt-F2 then type “r” in the box and hit ENTER and after Gnome 3 has restarted, you may run the gnome-tweak-tool and change the shell theme. And you can install a plugin that gives you a standard Gnome 2 styled foot menu! The Activities menu is still there, but this is very cool. Maybe this Gnome 3 desktop is not so bad after all. I wonder if these plugins are available in Ubuntu 11.10, I have heard that distribution has Gnome Shell. The alternative status menu option will give you a power off option in the status menu on the right hand end of the top Gnome 3 bar. I prefer to use Suspend though, the computer wakes up much faster using Suspend than powering off and back on again. And you can type su -c “init 0” in a terminal to shut down. So Unity 0, Gnome Shell 1.
