Ubuntu14.04设置自定义桌面分辨率

    在ubuntu14.04虚拟机上修改自定义大小的桌面屏幕分辨率,使用的命令: cvt,xrandr

0、首先查看下当前已经提供的分辨率设置:xrandr -q

root@xxx:/home/xxx/Desktop# xrandr -q
Screen 0: minimum 1 x 1, current 1504 x 768, maximum 8192 x 8192
Virtual1 connected primary 1504x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x600        60.0 +   60.3 
   2560x1600      60.0 
   1920x1440      60.0 
   1856x1392      60.0 
   1792x1344      60.0 
   1920x1200      59.9 
   1600x1200      60.0 
   1680x1050      60.0 
   1400x1050      60.0 
   1280x1024      60.0 
   1440x900       59.9 
   1280x960       60.0 
   1360x768       60.0 
   1280x800       59.8 
   1152x864       75.0 
   1280x768       59.9 
   1024x768       60.0 
   640x480        59.9 
   1504x768_60.00   59.9*
Virtual2 disconnected (normal left inverted right x axis y axis)
Virtual3 disconnected (normal left inverted right x axis y axis)
Virtual4 disconnected (normal left inverted right x axis y axis)
Virtual5 disconnected (normal left inverted right x axis y axis)
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)

红色部分是我标明的,Virtual1 设备名称,后面会用到,maximum 8192 x 8192最大支持分辨率;

1、在终端输入:cvt 1920 1080,显示如下:

root@xxx:/home/xxx/Desktop# 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

红色部分会在--newmode命令中用到,直接复制即可。

  

2、接下来通过--newmode、--addmode、--output命令即可完成,如下:

root@xxx:/home/xxx/Desktop# xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
root@xxx:/home/xxx/Desktop# xrandr --addmode Virtual1 "1920x1080_60.00"
root@xxx:/home/xxx/Desktop# xrandr --output Virtual1 --mode "1920x1080_60.00"

此时,屏幕分辨率已经改变了。

3.通过xrandr -q命令查看:

xrandr -q
Screen 0: minimum 1 x 1, current 1920 x 1080, maximum 8192 x 8192
Virtual1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x600        60.0 +   60.3 
   2560x1600      60.0 
   1920x1440      60.0 
   1856x1392      60.0 
   1792x1344      60.0 
   1920x1200      59.9 
   1600x1200      60.0 
   1680x1050      60.0 
   1400x1050      60.0 
   1280x1024      60.0 
   1440x900       59.9 
   1280x960       60.0 
   1360x768       60.0 
   1280x800       59.8 
   1152x864       75.0 
   1280x768       59.9 
   1024x768       60.0 
   640x480        59.9  
   1504x768_60.00   59.9
   1920x1080_60.00   60.0*
Virtual2 disconnected (normal left inverted right x axis y axis)
Virtual3 disconnected (normal left inverted right x axis y axis)
Virtual4 disconnected (normal left inverted right x axis y axis)
Virtual5 disconnected (normal left inverted right x axis y axis)
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)

红色部分是我添加的分辨率,1504x768的添加过程省略了。


4.如果想把自定义屏幕分辨率设置为永久有效,在~/.profile文件中追加如下:

vim ~/.profile

cvt 1920 1080

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"

:x 保存退出即可。
