vim 颜色方案在启动时不生效

我有一个问题，当我启动 VIM 时，我在 .vimrc 上设置的颜色方案在第一次运行 VIM 时不会生效，但是每当我执行:colorscheme 'mycolorscheme' 时，都会应用颜色方案。

我是 linux 的初学者，所以请多多包涵。

我只是在想是否应该设置一个设置。这是我使用 xterm 设置的设置。

.X资源

*customization: -color
XTerm*termName: xterm-256color

.xsession

if [ -f $HOME/.Xresources ]; then
     xrdb -merge $HOME/.Xresources
fi

运行后xrdb -query 输出如下：

*customization:-color
XTerm*termName: xterm-256color
Xft.dpi:    96
Xft.antialias:  1
Xft.hinting:    1
Xft.hintstyle:  hintslight
Xft.rgba:   rgb
Xft.lcdfilter:  lcddefault

顺便说一句，每当我想启动 VIM 时，只有颜色方案不会生效。但所有映射和其他设置都有效

这是我的 .vimrc

无论我使用什么终端模拟器，它都不起作用。gnome-terminal 或 xterm。看起来 colorsheme 确实已加载。首次加载时，键入 :colorscheme 会报告我在 .vimrc 上设置的正确颜色方案。但是第一次不会生效。我必须在 VIM 上输入
