Where is Trash Bin in Ubuntu 11.10 with Gnome Shell?
Solution 1:
Open a folder (any folder). In the sidebar, you'll see an entry for the trash. That's it.
Solution 2:
sudo apt-get install gnome-tweak-tool
Install that. Go to Applications > Other > Advanced
You can put a trash can and change your font.

Solution 3:
Just install the gnome-tweak-tool, start it via Alt-F2 and you can add the Trash icon (and others) to your desktop.
