+==== Gnome Terminal ====
+Gnome Terminal //does// support 256 colour mode, but doesn't always sets the ''TERM'' variable to ''xterm'', rather than ''xterm-256color''. There's no way to override this directly, but you can work around it by setting:
+Profile Preferences → Title and Command → Run a custom command instead of my shell → ''env TERM=xterm-256color /bin/bash''

 ===== OK, it does. Now how about Vim? =====
 See '':help xterm-color'' for the official documentation. It makes mention of 256 colours, but isn't hugely helpful.

 For gnome-terminal, the default Ubuntu terminal if you didn't customise your install, you can't change what it reports itself as: ''xterm''. My work around for this was to add the following snippet to my ''~/.bashrc'':
