If our Linux OS is using the X Window System, we can use the
xwd (X window dump) command there to make screenshots. This command is part of a package called
x11-apps. Under Debian-based operating systems 🔗, like Ubuntu, we can run
sudo apt install x11-apps to install it.
🚀 ~ xwd -out screenshot.xwd
The command above will provide us a pointer to select the window we want to make a screenshot of. The problem here is that when we have another window in the foreground, that window will be captured as well, as shown in the illustration.
To avoid this, we can use the
sleep command and have a delay before taking a screenshot to successfully minimize, close, or bring backward all other windows we don’t want to capture.
🚀 ~ sleep 5; xwd -out screenshot.xwd
🚀 ~ xwd -out screenshot.xwd 🚀 ~ convert screenshot.xwd screenshot.jpg
xwd will not include the window frame. To make it shown, we must use the
frame flag, like this:
🚀 ~ xwd -frame -out screenshot.xwd
And, finally, to make a screenshot of the entire screen with all windows, we should use the
root flag. All frames of all windows will be included in this case. There’s no need to specify the
frame flag when using the command with the
🚀 ~ xwd -root -out screenshot.xwd
It’s important to mention that the
xwd command doesn’t talk well or, sometimes, even allow window background transparency options. Keep this in mind when taking your screenshots with it. 🙂
