How do I find out screen resolution of my Linux desktop?

To find out the screen resolution of your Linux desktop, you can use one of the following methods:

1. Check the display settings: Depending on your Linux desktop environment, you may be able to check the screen resolution in the display settings. To access the display settings, you can usually right-click on the desktop and select "Display settings" or "Screen resolution" from the context menu, or you can search for "display" or "screen resolution" in the settings or control panel of your desktop environment. The display settings should show the current screen resolution and allow you to change it if needed.

2. Use the "xrandr" command: "xrandr" is a command-line utility that allows you to view and change the screen resolution of your Linux desktop. To find out the current screen resolution using "xrandr", follow these steps:

3. Open a terminal and type the following command: ``` sh xrandr ```
4. The output of the "xrandr" command includes a list of available screen resolutions and the current screen resolution, which is indicated by an "*" character. For example:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
   1920x1080     60.00*+  50.00    59.94  
   1680x1050     59.88  
   1600x900      60.00  
   1440x900      59.90  
   1280x1024     75.02    60.02  
   1280x800      59.91  
   1152x864      75.00  
   ...

5. The "current" line shows the current screen resolution, which in this example is "1920 x 1080".

With these methods, you should be able to find out the screen resolution of your Linux desktop.

Note: The screen resolution is the number of pixels (dots) that are displayed on the screen, and it is usually expressed as the width and height of the screen in pixels (e.g., "1920 x 1080"). A higher screen resolution means that more pixels are displayed.
