It was too frustating when I couldnt copy/paste to/from vim.
$ vim --version|grep clipb
+clientserver -clipboard +cmdline_compl +cmdline_hist +cmdline_info +comments
+xsmp_interact -xterm_clipboard -xterm_save
As you can see vim has disabled clipboard and xterm clipboard modules.
Luckily it can be fixed easilly by installing gvim on Arch like
$ sudo pacman -S gvim
Lets check now:
$ vim --version|grep clipb
+clientserver +clipboard +cmdline_compl +cmdline_hist +cmdline_info +comments
+xsmp_interact +xterm_clipboard -xterm_save
Modules present and copy/paste works fine! Great success!
