To install GNOME Shell Autohide Top Bar in Ubuntu 12.04 (for GNOME Shell 3.4), use the commands below:
sudo add-apt-repository ppa:webupd8team/gnome3
sudo apt-get update
sudo apt-get install gnome-shell-extensions-autohidetopbar
Once installed, reload GNOME Shell and activate the extension using GNOME Tweak Tool.If toggling autohide on/off doesn't work properly or you just want to change the value, open "extension.js":
gksu gedit /usr/share/gnome-shell/extensions/autohidetopbar2@werewolves.us/extension.js
And change the "const TIME_DELTA" value to something that works better for you, then restart GNOME Shell.If you're not using Ubuntu, you can download the extension from HERE.
