X Server Current Color Depth

C

The correct answer is C. xwininfo.

The X Server is responsible for managing graphical output on Linux systems. The X Server supports different color depths, which represent the number of colors that can be displayed at the same time on the screen.

To display the current color depth of the X Server, we can use the xwininfo command. The xwininfo command provides information about the X Server windows, including the color depth.

To use the xwininfo command to show the current color depth of the X Server, follow these steps:

1. Open a terminal window.
2. Type the following command: xwininfo -root
3. Press Enter.

The xwininfo command with the -root option shows information about the root window of the X Server, which represents the entire screen.

The output of the command includes several lines of information, including a line that shows the visual class and depth of the root window. The visual class represents the type of color model used by the X Server, while the depth represents the number of bits used to represent each pixel.

For example, the output of the xwininfo command might include a line like the following:

vbnetCopy code
Visual Class: TrueColor Depth: 24 planes 

This output indicates that the X Server is currently using a TrueColor visual class and a color depth of 24 bits (or 8 bits per color channel). This means that the X Server can display up to 16,777,216 different colors at the same time.

The other options listed in the question (A, B, D, and E) are not valid commands for displaying the current color depth of the X Server.
