前因
从ubuntu14.04升级到ubuntu16.04 ,一直以来都是用gedit编辑代码，一直用这嵌入式终端这个插件，
在ubuntu16.04上嵌入式终端的默认颜色和代码区的颜色一样，都是白色的，感觉看起来怪怪，于是乎疯狂
百度修改之，以下方法亲测有效
1.直接修改配置文件
1.1 配置文件地址 /usr/lib/x86_64-linux-gnu/gedit/plugins/terminal.py //其他ubuntu版本可能不是这个地址
1.2 sudo gedit /usr/lib/x86_64-linux-gnu/gedit/plugins/terminal.py
只需要修改如下：
#fg = context.get_color(Gtk.StateFlags.NORMAL)
#bg = context.get_background_color(Gtk.StateFlags.NORMAL)
bg = Gdk.RGBA(0, 0, 0, 1)
fg = Gdk.RGBA(1, 1, 1, 1)
修改后的文件如下
