the Icon of Gnome shell is missing from lightDM.. I had to manually add Gnome Shell to lightDM because it didn't install properly on my machine. now I don't now how to add the Icon to lightDM.

Im on Ubuntu 14.04


In 14.04 the gnome-session package was split so that there is also an ubuntu-session package. In a standard Ubuntu 14.04 install, the gnome-session part won't be installed by default, so if you only installed gnome-shell you won't get the /usr/share/xsessions/gnome.desktop xsession file which is what LightDM reads to add the session. So the fix is:

sudo apt-get install gnome-session

In previous versions both the Unity and gnome-shell xsession files were in the same package and installed by default so you only needed to install gnome-shell.

  • thanks you so much. that solved everything i had problems with in one go. – aceloop Apr 21 '14 at 22:54
