ubuntu添加並設置屏幕分辨率

我想要一個920x1080分辨率，但是Ubuntu的說面設置沒有這個分辨率，需要的一些參數都是從上個命令中讀取的，本文都用顏色標識了

 

# 查看當前機器的分辨率信息
$ xrandr
Screen 0: minimum 1 x 1, current 1680 x 1050, maximum 8192 x 8192

1856x1392 60.00
1792x1344 60.00

Virtual6 disconnected (normal left inverted right x axis y axis)
Virtual7 disconnected (normal left inverted right x axis y axis)
Virtual8 disconnected (normal left inverted right x axis y axis)

# 生成分辨率配置參數
$ cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

# 添加一個分辨率
$ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

# 綁定顯示器到分辨率
$ xrandr --addmode Virtual1 "1920x1080_60.00"

# 設置顯示器的分辨率
$ xrandr --output Virtual1 --mode "1920x1080_60.00"

 

這些命令設置完以后，ubuntu重啟設置又無效了，可以在/etc/profile中把最后三個命令加進去啟動自動執行

xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode Virtual1 "1920x1080_60.00"
xrandr --output Virtual1 --mode "1920x1080_60.00"
