gnome-shell-184.108.40.206 error in fedora 20 - solution
I ran Fedora 20 64-bit Live on my i5 64-bit PC and it ran fine. Gnome desktop worked fine. I ran install from live and when I logged in Gnome desktop would not start and generated an error message, " a problem occurred with gnome-shell-220.127.116.11 " and the system required me to logout and log back in.
Ctrl-Alt-F2 into tty2
yum update gnome* xorg* taglib*
Log back in ... Gnome should work
