The X Resize and Rotate Extension (RandR) allows clients to dynamically change X screens, so as to resize, rotate and reflect the root window of a screen. The initial X11 design did not anticipate the need for dynamic resizing and it was necessary to restart the X server to bring about the changes. RandR extension framework brought the ability to change display characteristics without restarting the X session. The extension framework allows laptops and handheld computers change their screen size to drive external monitors at different resolutions than their built in screens. [1] The current version of the protocol specification is 1.2.
If one's desktop environment doesn't provide a graphical tool for interfacing with this functionality, the xrandr command line tool may be used.

xrandr指令可以用來改變X環境的桌面大小和螢幕頻率. xrandr指令可以用来改变X环境的桌面大小和萤幕频率.
把桌面解析度調成1024×768:把桌面解析度调成1024×768:
$ xrandr -s 1024x768
把螢幕頻率調成75Hz把萤幕频率调成75Hz
$ xrandr -r 75
列出目前環境支援的解析度和頻率列出目前环境支援的解析度和频率
$ xrandr -q
它列出的訊息, 每行的第一個數字可以用來指定給-s 參數, 假設有一行這麼寫它列出的讯息,每行的第一个数字可以用来指定给-s参数,假设有一行这么写
20 640 x 480 ( 347mm x 260mm ) 75
那麼下那么下
$ xrandr -s 20
時, 就會把螢幕調成640×480 大小, 頻率75Hz时,就会把萤幕调成640×480大小,频率75Hz
如果有數個X環境同時運作的話, 可以用-d 參數去調整別的X環境, -d 後面加的是像:0 :1 :2 這樣, 例如:如果有数个X环境同时运作的话,可以用-d参数去调整别的X环境, -d后面加的是像:0 :1 :2这样,例如:
$ xrandr -s 800x600 -d :0
