Hmm, after the first time i test gnome-shell 3.0.0. on fedora 15, and slow simply slow on that system, now i try again this gnome-shell… first install, i just install the gnome-shell and gnome-session, and this is not work… then i just realize must install all of gnome dependencies so #pacman -S gnome is the right choice than install per part of it… then just edit your ~/.xinitrc for a little just add this line “exec dbus-launch gnome-session” done, don’t forget to comment the other u are using for, relog and login again, tada… a gnome-shell started… so what’s new??? i will say nearly nothing, but one thing i realiz is, gnome-shell on archlinux is pretty fast than the fedora’s… because the version??? i don’t know, surely the first thing you must do on gnome-shell is search for extensions, now there was a gnome-extension site here http://extensions.gnome.org , there will be many list extension u can use for your gnome-shell, and tweak…. don’t forget to install gnome-tweak tool, ah ya if you using notify-osd like, just remove it, it’s not integrated enough with gnome-shell… so this in my gnome-shell simple screenshoot on archlinux
