I apologize if this post is not in the right spot.
Anyway I copy and pasted about 6 new theme files to usr/share/gnome-shell and then hit alt-f2 r and the system went wiggy. Got the unhappy computer icon that said the system could not recover. Now I am in failsafe mode and have cd in root mode to /usr/share/gnome-shell. I would just like to know how to remove the files that I placed there. I called the files I placed in there theme 1, theme 2, etc...
Thank you for your time
