why the color theme is terrible in xterm of Ubuntu?

[liao20081228]

I use the theme in Ubuntu 16.04 , and I add

export TERM=xterm-256color

to ~/.bashrc, add

set t_Co =256 
set  background=dark
syntax enable
synatax on
colorscheme solorized

to ~/.vimrc.

I use xterm of Xshell5 in Windows to connect Ubuntu，but the vim is：
)

So, it is incorrect , and what should I do？Thanks！

Your .vimrc should at least look like this:

syntax enable

set background=dark
let g:solarized_termcolors=256
colorscheme solarized

You have a few little typos like synatax or solorized and you don't need syntax enable and syntax on
