XQuartz总是打不出“.”这个符号（MAC版）(For Mac: XQuartz cannot output this notion ".")_xquarz 的xterm打不上

“.”打不出来，怎么写服务器的IP！！方法来了哦～～

1. 打开XQuartz这个软件之后，选择“终端”或者也叫做“xterm”(open the software and then choose "xterm")

2. 点击mac最上面一行navigation bar，找到XQuartz的“偏好设置”(Click the navagation bar of Mac and then find the preferenc of XQuartz)

请注意了！(pay attention!)

3. 初始的是只有正数第三行的是打勾的，但是我们一定要把正数第二行的也勾上！然后你的xterm里面就可以打出“.”啦(Original setting: only the third line is clicked, but we alse need to click the second line. Then you can output "." in your XQuartz successfully)～
