I use zsh with oh-my-zsh and xfce4-terminal in XUbuntu 14.04.
If I configure xfce-terminal with xterm-256color, like this:

I get this error:
*** VTE ***: Failed to load terminal capabilities from '/etc/termcap'
If I leave the default setting, my terminal has 8 colors:
$ echotc Co 8 $ echo $TERM xterm If I export, like this:
$ export TERM=xterm-256color I get proper values and it seems that I have truly 256 colors:
$ echo $TERM xterm-256color $ echotc Co 256 But my zsh prompt doesn't show proper colors. For instance with agnoster theme:

I see proper colors in the output commands, but only 8 colors in the zsh prompt.
But using terminator I see all correct with xterm-256color:

The most funny part, is that terminator with only 8 colors, shows theme properly:

What I need to configure to continue using xfce4-terminal with 256 colors and proper theme colors?
