CentOS

Hi guys. First of all, excuse me for my poor English, and unlikely I'm gonna write a lot of English mistakes. I've got running Linux about 2003 and I got away for the last 6 years. For my sad surprise the most simple and ordinary functions on the desktop are still harsh to do. For example, auto-hide...

I've edited /usr/share/gnome-shell/theme/gnome-shell.css but no success. I commented all references to *bottom* and nothing happened.

Hello. Does anyone know how to remove the bottom bar in Gnome 3.8.4? Is there no way to "unlock" it?

Thank U all!
