Usage
maim
maim is aimed to be an improved scrot.
Save the full screen to file:
$ maim filename
Prompt for selection and save to file:
$ maim --select filename
Save the active window to file, assuming xdotool is installed:
$ maim --window $(xdotool getactivewindow) filename
Prompt for selection, save without cursor, and store it to clipboard, assuming xclip is installed:
$ maim -s | xclip -selection clipboard -t image/png -i
scrot
scrot enables taking screenshots from the CLI and offers features such as a user-definable time delay. Unless instructed otherwise, it saves the file in the current working directory.
$ scrot -t 20 -d 5
The above command saves a dated .png file, along with a thumbnail (20% of original), for Web posting. It provides a 5 second delay before capturing in this instance.
You can also use standard date and time formatting when saving to a file. e.g.,
$ scrot ~/screenshots/%Y-%m-%d-%T-screenshot.png
saves the screenshot in a filename with the current year, month, date, hours, minutes, and seconds to a folder in your home directory called "screenshots"
See scrot(1) for more information.
scrot -s
does not work properly when running via window manager's keyboard shortcut, this can be worked around by prepending scrot invocation with a short pause sleep 0.2; scrot -s
.Desktop environment specific
Budgie
Budgie ships with its own screenshot utility called BudgieScreenshot.
It allows capturing the whole screen using PrintScreen
, the active window or a selected area. See Keyboard Shortcuts for the shortcut to a specific action.
Cinnamon
The default installation of Cinnamon does not provide a screenshot utility. Installing gnome-screenshot will enable screenshots through the Menu > Accessories > Screenshot or by pressing PrintScreen
.
GNOME
GNOME users can press PrintScreen
or click the camera icon in the system menu. You can also optionally install gnome-screenshot and open it via Apps > Accessories > Take Screenshot.
GNOME features built-in screen recording with the Ctrl+Shift+Alt+r
key combination. A red circle is displayed in the bottom right corner of the screen when the recording is in progress. After the recording is finished, a file named Screencast from %d%u-%c.webm
is saved in the Videos
directory. In order to use the screencast feature the gst-plugin-pipewire and gst-plugins-good packages need to be installed.
KDE
If you use KDE, you might want to use Spectacle.
Spectacle is provided by the spectacle package.
Xfce
If you use Xfce you can install xfce4-screenshooter and then add a keyboard binding:
Xfce Menu > Settings > Keyboard > Application Shortcuts
If you want to skip the Screenshot prompt, type $ xfce4-screenshooter -h
in terminal for the options.
Other desktop environments or window managers
For other desktop environments such as LXDE or window managers such as Openbox and Compiz, one can add the above commands to the hotkey to take the screenshot. For example:
$ import -window root ~/Pictures/$(date '+%Y%m%d-%H%M%S').png
Note that import is part of the imagemagick package. Adding the above command to the PrintScreen
key to Compiz allows to take the screenshot to the Pictures folder according to date and time.
Notice that the rc.xml
file in Openbox does not understand commas; so, in order to bind that command to the PrintScreen
key in Openbox, you need to add the following to the keyboard section of your rc.xml
file:
rc.xml
<!-- Screenshot --> <keybind key="Print"> <action name="Execute"> <command>sh -c "import -window root ~/Pictures/$(date '+%Y%m%d-%H%M%S').png"</command> </action> </keybind>
If the PrintScreen
above does not work, see Keyboard input and use different keysym or keycode.
Packages including a screenshot utility
ImageMagick/GraphicsMagick
See ImageMagick#Screenshot taking.
GIMP
You also can take screenshots with GIMP (File > Create > Screenshot...).
imlib2
imlib2 provides a binary imlib2_grab
to take screenshots. To take a screenshot of the full screen, type:
$ imlib2_grab screenshot.png

Wayland
Capturing the screen on Wlroots-based compositor can be done using grim or grimshot (from sway-contrib), for screenshots and wf-recorder (or wf-recorder-gitAUR) for video; wlrobs-hgAUR is an obs-studio plugin that allows you to screen capture on wlroots-based compositors. Optionally, slurp can be used to select the part of the screen to capture. If your GPU supports vaapi encoding, wl-screenrec-gitAUR can be a more efficient alternative to wf-recorder.
Take a screenshot of the whole screen:
$ grim screenshot.png
Take a screenshot of current window in Sway:
$ swaymsg -t get_tree | jq -r '.. | select(.focused?) | .rect | "\(.x),\(.y) \(.width)x\(.height)"' | grim -g - screenshot.png
Take a screenshot of current window in Hyprland:
$ hyprctl -j activewindow | jq -r '"\(.at[0]),\(.at[1]) \(.size[0])x\(.size[1])"' | grim -g - screenshot.png
Take a screenshot of a part of the screen:
$ slurp | grim -g - screenshot.png
Take a screenshot of a part of the screen and put the output into the clipboard using wl-clipboard:
$ slurp | grim -g - - | wl-copy
Capture a video of the whole screen:
$ wf-recorder -f recording.mp4
Capture a video of a part of the screen:
$ wf-recorder -g "$(slurp)"
- screenshot.sh GUI Screenshot Tool for Wayland Using zenity, grim and slurp
Additionally, some programs mentioned above work under Wayland (e.g. ksnip, green-recorderAUR).
Screencasting
Via GNOME screencast
green-recorderAUR, obs-gnome-screencastAUR and obs-studio support screen recording on Wayland using GNOME screencast feature.
Via Hyprland
The Hyprland window manager allows screen casting and recording with OBS (including selection of individual windows and workspaces) when used with xdg-desktop-portal-hyprland [1].
Via a virtual webcam video feed
See v4l2loopback#Casting Wayland using wf-recorder.
- This method has been tested with zoomAUR (desktop client running under xorg-xwayland) and BigBlueButton under chromium (under firefox the resolution is really low); skypeforlinux-binAUR detects the virtual video device
VirtualVideoDevice
, but outputs a blank screen. - The example uses
wf-recorder
but you can use whatever software, just feed the output to the virtual device.
Install wf-recorder (or wf-recorder-gitAUR) and v4l2loopback-dkms. Load the v4l2loopback
kernel module with the following parameters:
# modprobe v4l2loopback exclusive_caps=1 card_label=VirtualVideoDevice
Verify that a new virtual video device VirtualVideoDevice
has been created:
$ v4l2-ctl --list-devices
... VirtualVideoDevice (platform:v4l2loopback-000): /dev/video2 ...
Start recording the screen with wf-recorder
and feed the output to the new virtual video device VirtualVideoDevice
created by v4l2loopback
:
$ wf-recorder --muxer=v4l2 --codec=rawvideo --file=/dev/video2 -x yuv420p
The yuv420p
colour space is required for the video output to be compatible with Zoom [2].
Unknown V4L2 pixel format equivalent for rgb0
run wf-recorder
with --force-yuv
or -t
to force conversion of the data to yuv format, before sending it to the GPU. [3]
You can now select the above virtual video device as your "webcam" in video calling/video conferencing applications (the device is called VirtualVideoDevice
). You can use ffplay
(part of ffmpeg), mpv, or gst-launch
(part of gstreamer) to verify that the virtual video device indeed outputs your screenshare:
$ ffplay /dev/video2
$ mpv av://v4l2:/dev/video2
$ gst-launch-1.0 -v v4l2src device=/dev/video2 ! glimagesink
If Firefox is unable to read the video stream and prints a message like "AbortError: Starting video failed", try preloading v4l2compat.so
:
$ LD_PRELOAD=/usr/lib/v4l1compat.so firefox
Sharing individual applications
As explained above, wf-recorder
is able to record only a portion of the screen by first selecting a region with slurp. To use this functionality for sharing a specific region/application window through a virtual video device, start recording the screen with the following modified command:
$ wf-recorder -g "$(slurp)" --muxer=v4l2 --codec=rawvideo --file=/dev/video2 -x yuv420p
After selecting a region of the screen, you will be able to access the video feed through the virtual video device /dev/video2
as above.
Via the WebRTC protocol
See PipeWire#WebRTC screen sharing.
Chromium and Firefox should now be able to access the screenshare. You can verify this through Mozilla's getUserMedia / getDisplayMedia Test Page.
Screencast Wayland windows with X11 applications
You can share native Wayland windows (or the whole screen/workspace) to the X11 application. For this you need to use xwaylandvideobridge. See Fixing Wayland: Xwayland screen casting for details.
Terminal
Capture with ANSI codes
You can use the script(1) command, part of the util-linux package.
Just run script
and from that moment, all the output is going to be saved to the typescript
file, including the ANSI codes.
Once you are done, just run exit
and the typescript
would ready. The resulting file can be converted to HTML using the ansi2htmlAUR package (not to be confused with ansi2html from python-ansi2html).
To convert the typescript
file to typescript.html
, do the following:
$ ansi2html --bg=dark < typescript > typescript.html
Actually, some commands can be piped directly to ansi2html:
$ ls --color|ansi2html --bg=dark >output.html
That does not work on every single case, so in those cases, using script
is mandatory.
Framebuffer
Install a framebuffer and use fbgrab or fbdumpAUR to take a screenshot.
Virtual console
Screenshot
If you merely want to capture the text in the console and not an actual image, you can use setterm
, which is part of the util-linux package. The following command will dump the textual contents of virtual console 1 to a file screen.dump
in the current directory:
# setterm -dump 1 -file screen.dump
Root permission is needed because the contents of /dev/vcs1
need to be read.
Screencast of console
asciinema allows to record a whole terminal session activity, which is saved in a file in its own (open) format. This file can be played with the same tool or an HTML5 version of the tool, and can be shared on the asciinema.org official web site of the application, or on any own hosted HTML version.
Usage: asciinema(1) or asciinema --help
.
-
asciinema rec output.cast
records the session,Ctrl+\
can pause/resume it,Ctrl-d
/exit of the session will stop it. Name of output file is optional.
Interesting arguments for recording:
-
-c command
if you just want to record a specific command action/output -
-i 1.2
record for 1.2 seconds only -
-t "beautiful title"
add a title to the terminalcast
Other functions than recording:
-
asciinema play file.cast
play an asciinmea record file -
asciinema upload file.cast
upload the file on asciinema.org for sharing -
asciinema auth
manage recordings on asciinema.org account
Troubleshooting
Screenshot uses old screen state
See KDE#Spectacle screenshot uses old screen state.
NVIDIA clipping background
If the nvidia proprietary driver is in use and the screen recording is experiencing background clipping, enable the ForceCompositionPipeline
setting. See NVIDIA/Troubleshooting#Avoid screen tearing for details.
