Gnome 3 devs are stupid enough to remove features before some replacement is implemented. Simplified nautilus and (what's much more important for me!) broken keyboard layout configuration. Well, you still can configure what layouts to use, but you can't choose usual shortcut to switch layout, and you can't configure led to indicate alternative layout.
Well, I still can use setxkbmap (setxkbmap -layout "us,ru" -option "grp:caps_toggle,grp_led:scroll"), but that's f***ing ridiculous to remove things that were working here for years and propose nothing for replacement! They broke core functionality (who can work without a keyboard?!), and it makes me sick!
Update: more haterays to gnome-devs! Gnome 3 overrides xkbmap settings somewhere, I wonder if there's a way to prevent it...
Update-2: you can remove gnome-settings-daemon keyboard plugin as a workaround (sudo rm /usr/lib/gnome-settings-daemon-3.0/libkeyboard.so)
