[Tips] Switch to External Monitor in LXDE

之前換了國人自製的LXDE,發現有些設定不太一樣,比如說想要將螢幕投到外接螢幕,function按鍵就沒作用,非要重開機才能正常,爬了一下文才發現原來LXDE還有做這樣的螢幕管理工具,說明如下:

Description: simple monitor config tool for LXDE This is a very basic monitor config tool utilizing the X extension called RandR. It can let you change the screen resolution on the fly. Besides, when you run lxrandr with external monitor connected, its GUI will change, and show you some quick options to get your projector or external monitor working correctly.

執行方式就是直接呼叫

$ sudo lxrandr

預設執行起來應該是這樣

如果有外接螢幕就會變成這樣

選擇正確的輸出就可以快樂的投影了
