Q:

Vim colorscheme background not filling terminal

I am using vim with lxterminal, and the colorscheme kolor, and I am experiencing an issue where vim's background color does not fill the entire terminal.

It can be seen clearly at the bottom of this screenshot, as you can see the color of my terminal. My .vimrc is as follows;
syntax on          " Enable syntax highlighting

set number         " Enable line numbers
set smartindent    " Automatically indent text
set tabstop=4      " Set tab width to 4 spaces
set shiftwidth=4   " Indent text when using '>'
set expandtab
set nocompatible   " Disable compatibility mode (prevent ABCD key bugs)
set viminfo=

filetype plugin on " Enable filetype plugins

au BufNewFile,BufRead *.ino set filetype=cpp " Alias arduino (ino) files

I have tried changing my TERM environment variable to screen-256color, but to no avail. TERM is currently set to xterm-256color.

A:

You have to change change LXTerminal theme to kolor also, because from what I see, you are using solarized for the terminal.
