Linux Mint Xfce

By default, Ubuntu (so as to Linux Mint) installs the vim-tiny package, which is a ultra-light version of the console "vim" only.

To check the clipboard support of the installed vim, run vim --version|grep clipboard. If you get "-clipboard" and "-xterm_clipboard", your vim can't support system clipboard. You have to remove current vim, and install a "full" version vim like this:

$ sudo apt-get purge vim 
$ sudo apt-get autoremove # remove related packages of vim 
$ sudo apt-get install vim-gtk # gtk suited for Xfce environments

Now let's check:

$ vim --version | grep clipboard

You should get something like "+clipboard" and "+xterm_clipboard".

Now connect vim clipboard with that of system with adding "set clipboard=unnamedplus" into you ~/.vimrc. And check it:

1. Copy texts in web browser with Ctrl-c, and use "p" to paste them in vim;

2. copy a line in vim with "yy", then paste them into some GUI program (say, gedit) with Ctrl-v.

ArchLinux

Install gvim with sudo pacman -S gvim.

Note: On CentOS, use yum search vim to get the exact vim package name. On CentOS 6.4 it's "vim-X11".
