xshell 中使用vim 显示Xmanager运行失败：

xshell 中使用vim 时显示
Xmanager运行失败：
请检查此系统的Xmanager是否已正确安装。

问题原因：
This problem occurs when VIM is trying to run as an X application with a full GUI interface and mouse support. You can suppress it by using 'vi -X' or 'vim -X' option.
If this doesn't work, check out your vi manual to see which option turns off the X application mode.

解决方法
1，vim -X
2，unset DISPLAY
3，调整session配置文件
