如何使用命令行获取显示器分辨率？

Question

我想找到最适合我的分辨率的壁纸。如何仅通过在命令行中编写命令来获得分辨率？

Answer 1

取自这个答案：

xdpyinfo | grep dimensions

或者只获得分辨率：

xdpyinfo | awk '/dimensions/{print $2}'

或者

xdpyinfo  | grep -oP 'dimensions:\s+\K\S+'

Answer 2

我只会使用xrandr：

$ xrandr 
Screen 0: minimum 320 x 200, current 3520 x 1200, maximum 32767 x 32767
LVDS1 connected 1600x900+1920+0 (normal left inverted right x axis y axis) 310mm x 174mm
   1600x900       60.0*+
   1440x900       59.9  
   1360x768       59.8     60.0  
   1152x864       60.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm
   1920x1200      60.0*+
   1920x1080      60.0     50.0     59.9     24.0     24.0  
   1920x1080i     60.1     50.0     60.0  
   1600x1200      60.0  
   1280x1024      75.0     60.0  
   1152x864       75.0  
   1280x720       60.0     50.0     59.9  
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   720x576        50.0  
   720x480        60.0     59.9  
   640x480        75.0     60.0     59.9  
   720x400        70.1  
HDMI2 disconnected (normal left inverted right x axis y axis)
HDMI3 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
DP3 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

这里我有两个屏幕，分辨率是：

• 1600x900（笔记本电脑）
• 1920x1200（显示器）

要仅获得主显示器的分辨率，您还可以使用此 python oneliner：

$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
geo = screen.get_monitor_geometry(screen.get_primary_monitor()); \
print(geo.width, "x", geo.height)'
1920 x 1200

要获得扩展桌面的分辨率（用于多显示器设置）：

$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
print(screen.get_width(), "x", screen.get_height())'
3520 x 1200

Answer 3

请求是为了决议。这是由

xdpyinfo | grep resolution

Answer 4

您还可以使用：

 xrandr | grep ' connected'

我的其中一台机器上的输出示例：

LVDS connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm

Answer 5

在没有 X 的树莓派上，我可以通过运行以下命令来获取屏幕分辨率：

fbset -s
