Brightness Controller Extension

[Argenta Sugden]

Thebrightness of your screen can influence how you consume contents online. Think about the pain of glaring at a high bright screen for hours. This horrific event is why many of us are plagued with perpetual eye strain, painful eyes, headaches, and migraines. Fortunately, you can transform that experience for the better by adjusting the brightness of a website.

Adjusting the brightness of a website demands involves dimming the backlight of any website. However, you need the best chrome brightness extension to adjust the brightness of any website and combat eye strain. The right tool should allow you to modify the daytime and night-time brightness on your screen to your desired level. This article will talk about the benefits and how to adjust the brightness extension on any website.

For avid lovers of the internet, the Night Eye integrates with diverse browser selections giving you a compatible tool that works flawlessly. However, this guide focuses on the Night Eye as the best chrome brightness extension to dim any website. Use this guide below to install the Night Eye on your chrome browser, and start using its dim feature to reduce brightness across all web pages you wish to visit.

Using dark mode and reduced brightness features offers solid protection against eye-related problems. Plus, you will enjoy longer battery life on every recharge. When you enable dark mode and apply the dim feature, you can say goodbye to vision problems, undue stress, brain fog, and many more.

This extension reduces or increases the screen brightness level for both daytime and nighttime periods based on user-defined values. It helps the websites that do not support the native dark theme. Also, it can increase the brightness of websites that are too dark. It reduces the eyestrain while reading documents online when dark mode is not supported. The extension offers two different values for daytime and nighttime duration to enhance usability.

Features:

1. Control the darkness level of all websites or just a single hostname

2. You can increase or decrease the brightness level of a website

3. Supports keyboard shortcuts for every action.

4. You can disable the extension on a single website or entirely

5. Control the brightness level from 0% (completely dark) to 120% (20% brighter than the original)

6. Supports two different methods to decrease the brightness level.

Notes:

1. By setting the brightness level to 100%, the extension does not affect browser tabs (does not inject any CSS styling)

2. It is recommended to configure the start time for both daytime and nighttime. By default, daytime starts at 08:00, and nighttime starts at 19:00.

3. By adding a website to the exception list, brightness control is turned off for this website. You can use this feature to turn off the extension on websites that support native dark mode.

4. This extension does not reduce the screen brightness when printing a webpage. There is a CSS selector that only affects "screen" type displays.

I have installed Ubuntu 16.04 LTS on my laptop and connected it to an external monitor via an HDMI cable. I can easily change the brightness of the laptop screen but that does not affect the brightness of the external monitor. Is there any way to change the brightness of the external monitor as well?

This ddcci driver integrates all ddcci-capable monitors into sysfs, including /sys/class/backlight/.Because i.e. GNOME will use that interface to set the brightness, you can set the brightness without an additional UI, or the terminal.

The brightness controller mentioned before is now version 2. The original simple version is available using the following steps with support for up to 4 monitors. Tested working without issue on Ubuntu 14.04 and 16.04.

To "dim" your external monitor, you can use a program like f.lux, who will remove some colors (blue, mainly) from the GPU output. The result is that the image will look less "aggressive" for your eyes.

But every time I hit the command the brightness of the secondary display reduces for a second and reverts back. Then I found the reason behind it.I was using Redshift and it is periodically overriding all other settings. Simply exit redshift (if you're experiencing the same issue) and try the xrandr command again.

bashrc file is a script file that's executed when a user logs in. It contains a series of configurations for the terminal session. Like setting up or enabling: coloring, completion, shell history, command aliases, and more.

Compiling some of the answers here and elsewhere I made an xbindkey script to change main screen and second screen brightness (and other things such as volume) using mouse wheel or other control keys, it may be of some help : -guile-mouse-altkeys-and-more

Notably, as you might notice, ddcutil setcvp may be quite slow.To accelerate you might use --async option for multithreading and --noverify option once you are sure what you are doing.The main slowing issue is the implicit call of ddcutil detect, so you may want to note the bus number of the screen gave by this command as illustrated below:

I'm new to Linux, so I use Linux on dualboot. At the first time of installing Ubuntu, the brightness slider was working fine but when I made some updates + installed an Nvidia driver the slider is not doing anything anymore. Tried adding GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor to /etc/default/grub but didn't work. Tried to install Brightness Control as a temporary solution but even that wasn't working.The /sys/class/backlight folder has two folder in it; amdgpu_bl0 and ideapad, brightness slider only effect the files included in ideapad folder. What should I do?System specs:Ryzen 5 4600HGTX 1650 Ti

Thanks to this post, I am able to change the screen brightness.Go to /etc/grub and find GRUB_CMDLINE_LINUX= and add amdgpu.backlight=0 to there. Solved my issue in Fedora and Kubuntu both so the problem is the Radeon Graphics iGPU I guess.

Hope I'll still be in help. The best solution is to install a gnome shell extension called "Soft Brightness Plus", which allow you to change the screen brightness with both you keyboards and the slider.

Then you may go into the browse tab, find the extension and install it. Then return to the "Installed" tab, select the gear icon on the extension and turn on "Use backlight control"Extension github page: -brightness-plus.git

Just wanted to share that I tried a plethora of methods related to the grub configurations without any success, but I managed to solve this issue by simply updating the linux kernel. I had linux 22.04 LTS kernel 5.15 and updated it to 5.19.11-051911-generic.

My machine had 2 directories under /sys/class/backlight: amdgpu_bl0 and nvidia_0 and I was able to manually change the brightness value in the /sys/class/backlight/amdgpu_bl0/brightness with sudo. At first I thought it was because of the NVIDIA drivers but after uninstalling them the problem persisted. After the kernel update I no longer had the nvidia_0 folder in the /sys/class/backlight.

As the subject states, looking for a brightness app / extension that can control my External Monitor. I currently have a laptop with an external monitor connected (over USB-C), and the default brightness app only controls the monitor internal display.

Here is my sample xrandr command, with VGA-1 being the external monitor. I have the laptop screen pumped up on the gamma in the KDE gamma settings and so to compensate I had to lower the gamma output on the external display. You could start with values of 1 for red, blue and green and experiment from there.

Hmm ok I will install gnome tweaks and maybe try some extension, yes it's a QT application I always don't like that two toolkits look weird, when I was using KDE I always cringed when I see a GTK application on KDE

linux for hardware support has always had various glitches, my oled monitor in zorin can not adjust the brightness, but also need to use third-party methods to be able to, but pop os can perfectly support oled monitors, but pop os also has a disadvantage for the thunderbolt 3 support is not too good.

Though it is software-only modification, it does the trick anyway. According to the man page, xrandr is the primitive command line interface to RandR extension, so it is quiet possible to change my monitor brightness programmatically. However, I didn't find any related API in its header file .

First of all, this is the specific monitor I bought: UltraFine 4K 21.5" model 22MD4KA-BThe first problem was that this monitor is USB-C only.No HDMI or DisplayPorts.I figured out a solution but this isn't a blog post for that problem.The other issue was, there are no buttons anywhere on the monitor!A common task such as changing the brightness can't be done on Linux.On macOS you are expected to use the on-screen controls for this but they didn't exist on Linux.It's all good.

I broke out Vim (my text editor), Google, and went to working creating a command-line solution to this problem.Suprisingly it worked and now I had a little tool to raise and lower the brightness of my screen, finally!Covid hit, I got sick and spent less time in the office.Two years later I moved and my office equiptment spent months and months in boxes.Unsuprisngly, my little project grew stale.

A few days ago I built my new office in my new home, dusted off my monitors, and rediscovered this problem and the need for my project.Before I put time into my project to bring it up-to-date I decided to do some research.There were needs by others out there for a project like this to not just work in the terminal, but through GNOME.I also saw requests to make it work for multiple of these monitors at the same time.Fortunately I found a couple of projects that work together to meet all of these goals: a command-line tool and a GNOME extension.This means I can archive my project and work together on the extension to support more models than I did, and look better doing it. ?
