Well, you can adjust your screen brightness for your eyes but at some point. Dimmer lets you make your dark screen to darker. It is a free utility for setting the brightness of your main screen as well as external monitors. You can choose which screens will be set to the selected brightness level. Perfect for dark room, planetariums or anyone working in the dark with multiple monitors. For video presentations use dimmer to dim your laptop screen, while leaving the VGA output at full brightness on the projector. From the system tray you access Dimmer slider, the range from 0% (Means full brightness) to all the way to 100%.

Green Recorder is a simple, open source desktop recorder developed for Linux systems built using Python, GTK and FFmpeg. It supports most of the Linux desktop environments such as Unity, Gnome, Cinnamon, Mate, Xfce and so on. Recently it has been updated to work with Wayland too in Gnome session.
It uses FFmpeg libraries and currently supported formats are: MKV, MP4, AVI, WMV, NUT and WebM (it only available for Wayland in Gnome session). You can choose the area to record, or use handy option ' Select a Window' to record a specific window, if you don't use any of these option and simply hit 'Record' button then it will record full-screen of the desktop. You can stop the recording process easily by right-clicking the icon and choosing 'Stop Record'. Or middle-clicking the recording icon in the notifications area (but doesn't work on all interfaces). Show Mouse and Follow Mouse are great options to have, you can adjust them as per your needs.
It uses default audio device on your system, you can record audio using Microphone or completely disable mic using its option, you can also change audio input source. Advanced options allows you to set Frames, delay to record the screen, Audio input source, as well as lets you run the command after recording is stopped.
By default, On Wayland only, Green Recorder uses the V8 encoder instead of the default V9 encoder in GNOME Shell because of the CPU & RAM consumption issue with V9. Which - now - should also give you better performance. On Xorg, each format uses its own default encoder.

What do you say about this application?
Are you a Laptop user who installed Linux and want to give it a try? There is no doubt that Linux is great operating system but still there are some small issues floating around and should be fixed. We hope these small issues will be fixed in future releases of Linux. Now a days many users who use other OS(s) migrate to Linux and most of the time very first distribution they install is Ubuntu because it is easy to setup, essential applications are included and it works out of the box for all kind of users.
Qterminal is a Qt-based multitab terminal forked from QTermWidget, it is lightweight, open-source, specially designed for LXQt desktop environment. Author of QTermWidget had no time to make it more advanced, thus this fork was created. Unlike Tmux or Screen, it is much easier to deal with it.
"Initially this project was started as an attempt to create relatively light and stable terminal emulator application like Konsole or gnome-terminal but without any dependency from such monsters as KDE or Gnome. The author was looking for such kind of application for a long time but haven't found anything worth while."
It offers features like vertical and horizontal terminal split, zoom in or out, terminal tabs switcher, background color scheme adjustments (choose from predefined schemes) or change background image, font resizing, shortcut keys, hide/show scroll bars and windows borders, and many more from preferences.
Using Multiplexer features you can create as much multi-screens in one terminal window as you want, you can kill the current window, copy text between windows, scroll with in split window using mouse, easily switch between windows, etc. All windows run their programs completely independent of each other. Professional may find it useful and very handy with a lot of features.

Tmux Terminal Multiplexer

Tmux is a terminal multiplexer, it enables a number of terminals (or windows) to be accessed and controlled from a single terminal. Tmux is intended to be a simple, modern, BSD-licensed alternative to programs such as GNU screen. Tmux may be detached from a screen and continue running in the background, then later reattached.
When Tmux is started it creates a new session with a single window and displays it on screen. A status line at the bottom of the screen shows information on the current session and is used to enter interactive commands.
A session is a single collection of pseudo terminals under the management of Tmux. Each session has one or more windows linked to it. A window occupies the entire screen and may be split into rectangular panes, each of which is a separate pseudo terminal. Any number of TMUX instances may connect to the same session, and any number of windows may be present in the same session. Once all sessions are killed, Tmux exits. Also checkout Tmux manual.
