I am currently running Ubuntu Gnome 14.04. I wanted to stop users from changing their wallpaper, so i followed this guide: How to block the desktop background from being changed?
After I ran the first command, all windows in my session closed, then the terminal closed. I logged out and logged back in and still couldn't do anything. So I logged in as root and tried running the second command. The terminal comes back with a message saying the file doesn't exist. I browsed to /usr/bin and the file is not there. What do I do? I can only login as root(and I don't want to do that) Is there a way for me to retrieve that file? Can someone upload their unmodified file so that I could place the file back and chmod it to 755? I need some quick help as I will soon need my account for a school presentation.
/usr
, all of/usr/bin
and so on...
