How To Use Two Different Wallpapers for ‘Light’ and ‘Dark’ Mode on Android

GNOME 42 introduced a new feature allowing for dual-tone wallpapers that automatically adapt to the system's dark or light mode. This means that when a user switches between light and dark themes, the wallpaper also changes its variant accordingly, providing a more cohesive visual experience. The feature is accessible through the Background section within the Settings > Appearance menu. However, users might encounter an issue where this functionality is not immediately available, presenting an empty Background section in the settings. This article addresses the common problem of missing dark and light wallpaper variants in GNOME 42. It outlines a straightforward solution for users experiencing this issue, particularly for those running Arch-based distributions. The primary fix involves installing the `gnome-backgrounds` package using the distribution's package manager. For Arch-based systems, the command `sudo pacman -S gnome-backgrounds` is specified. Before proceeding with the installation, users are advised to verify that their system is indeed running GNOME 42 by checking the "About" section in their system settings. The installation of this package is designed to be seamless, with changes taking effect immediately without requiring a restart or even a logout. Once installed, the dual-mode wallpapers should appear in the Background section, allowing users to select a pair that dynamically adjusts with their system theme. While the `gnome-backgrounds` package provides a selection of pre-designed dual-themed wallpapers, the article also caters to advanced users who wish to create their own custom dark and light mode wallpaper sets. This more involved process requires users to download two distinct images, one for the light mode (e.g., `image-l.jpg`) and one for the dark mode (e.g., `image-d.jpg`). These images then need to be placed into a specific directory: either `/usr/share/gnome-background-properties` for system-wide availability or `~/.local/share/gnome-background-properties` for a single user. Following this, users must create a custom XML file within the `gnome-background-properties` folder. This XML file, based on a template from GNOME's GitLab repository, needs to be edited to specify the paths to the custom light and dark wallpaper images. Once the XML file is correctly configured and saved, the custom dual-themed wallpapers become selectable from the system settings. The article acknowledges that this advanced method requires a certain level of technical proficiency and also references a video tutorial for those needing further visual guidance. #GNOME42 #LinuxCustomization #DesktopEnvironment #DarkModeBanner #LightModeBanner #WallpaperManagement #ArchLinux #SoftwareInstallation

The Google Pixel 2 introduces a dynamic theming feature that adjusts the user interface based on the chosen wallpaper. While Android has long offered customization through OEM modifications and third-party tools, the Pixel 2 integrates a form of theming directly into its operating system, leveraging capabilities introduced in Android Oreo. Out of the box, the device displays a white UI when using its default light-colored wallpaper, which features a beach scene with moving waves. The UI incorporates many transparent elements, contributing to a cohesive visual experience. The most notable change occurs when a dark-colored wallpaper is applied. Upon switching to a predominantly dark background, several key UI elements automatically transform to a darker aesthetic. Specifically, the app drawer, which is typically white, switches to a black background. Beyond the app drawer, the notification tray and quick settings panel also adopt a black interface with white text, enhancing readability and visual consistency with the dark wallpaper. However, it is important to note that individual notifications themselves do not undergo this color inversion. Further demonstrating this adaptive theming, the volume indicators and the refreshed power menu on the Pixel 2 also receive the dark makeover. This means that when a user adjusts the volume or accesses power options, these UI components will align with the overall dark theme activated by the wallpaper. This implementation represents a significant step towards more integrated and responsive UI customization on Android devices, moving beyond static themes or limited options. While the current iteration of this dark theme functionality is tied to wallpaper selection and does not extend across the entire system or offer full user customizability, it is seen as an important initial development. The article expresses optimism that this feature could evolve in future updates, potentially offering users more comprehensive control over system-wide theming. This semi-automatic theming capability provides users with a more personalized and aesthetically pleasing experience, particularly for those who prefer darker interfaces. It also highlights Google's ongoing efforts to enhance the user experience and visual flexibility of its Pixel devices. #GooglePixel2 #AndroidOreo #DarkTheme #UIcustomization #WallpaperAdaptiveTheme #PixelFeatures #AndroidTheming

Google Pixel 2 devices running Android 8.1 included a limited dark mode feature that activated based on the selected wallpaper. This feature, while a step towards a system-wide dark mode, restricted users to only dark-colored wallpapers to maintain the dark theme. The article details a method to circumvent this limitation using a third-party application called LWP+, enabling users to apply a dark theme regardless of their chosen wallpaper. The LWP+ application, available for free on the Google Play Store, acts as a live wallpaper manager. It allows users to select any image as their background while manipulating how the Android system perceives the wallpaper's color. This manipulation tricks the operating system into activating its dark mode UI elements, such as the app drawer and notification shade, even when a light-colored image is set as the wallpaper. The process involves four main steps. First, users need to download and install the LWP+ app from the Play Store. The app itself is free and doesn't contain in-app purchases, though it may display occasional advertisements. Second, users must set LWP+ as their active wallpaper. This is done through the standard wallpaper picker on their Android device, typically by long-pressing on the homescreen, selecting 'Wallpapers,' and then choosing LWP+ from the 'Live Wallpapers' section. The third step involves selecting the desired background image within the LWP+ application. After opening LWP+ from the app drawer, users can access an option labeled "select background image" to browse and choose any picture stored on their device. This allows for personalization without sacrificing the dark mode functionality. The final and crucial step is to activate the custom color settings within LWP+. Users need to navigate to the "OS Colors" section within the app and toggle on "custom colors." Then, all color settings should be set to black. This configuration ensures that Android consistently recognizes the wallpaper as dark, thereby maintaining the dark theme across supported UI elements. This workaround is particularly useful for owners of devices running Android 8.1, including the Google Pixel, Pixel 2, and Essential Phone, who desire the aesthetic and potential eye-strain benefits of a dark mode but do not wish to be limited to dark wallpapers. The article highlights that while Google had not yet implemented a comprehensive dark mode across all Android versions at the time, this application provided a practical solution for specific devices to achieve a more consistent dark theme experience. #GooglePixel #Android #DarkMode #LWPPlusApp #WallpaperCustomization #Android8_1 #Pixel2 #EssentialPhone

The article delves into the efficacy of using black wallpaper to conserve battery life on Android devices, differentiating its impact based on display technology. It explains that this common advice is true, but not universally applicable, as its effectiveness hinges on whether the device uses an AMOLED (Active Matrix Organic Light Emitting Diode) or LCD (Liquid Crystal Display) panel. AMOLED is highlighted as the newer and more efficient technology, where pixels generate their own light. When an AMOLED pixel displays black, it is entirely off, consuming no power. Conversely, to display any color, including white, the pixels must turn on and consume power. This characteristic makes AMOLED panels ideal for features like ambient displays, as only the necessary pixels are activated, leading to significant power savings when black backgrounds are used. In contrast, LCD technology, which is more common and established, operates differently. LCD panels require a constant backlight (LED) to illuminate the pixels. This backlight remains on regardless of the color being displayed. Pixels in an LCD panel are composed of sub-pixels that filter light from this backlight through red, green, and blue components. The article details the intricate mechanism of LCDs, explaining that they consist of multiple layers, including polarizers and liquid crystals. These liquid crystals, when an electrical current is applied, untwist their natural helix structure to block light. To produce the color black, the liquid crystal must be completely untwisted, requiring the maximum amount of current and, consequently, the greatest power consumption. Therefore, brighter colors, such as white, are actually more power-efficient on LCD screens, though the difference in battery consumption is generally marginal compared to AMOLED. The article emphasizes that while using black backgrounds can notably reduce power consumption on AMOLED displays, it does not offer the same benefit for LCDs. For LCD screens, white or brighter colors are marginally more efficient in terms of power usage. Overall, the key takeaway is that AMOLED displays inherently use less power than LCDs, particularly when displaying black. This understanding allows users to optimize their device's battery life by choosing appropriate display settings and themes based on their phone's screen technology. The explanation includes technical details on how each display type renders colors and consumes power, providing a comprehensive insight into the topic of display-related battery efficiency. #AndroidBattery #AMOLEDDisplay #LCDDisplay #BatterySavingTips #MobileTechnology #SmartphoneOptimization #DisplayTechnology

This article introduces Pywal, a Python-based command-line utility designed to automatically change the color scheme of a Linux terminal based on the colors extracted from the current desktop wallpaper. Pywal aims to enhance the aesthetic appeal of the Linux desktop environment by ensuring visual consistency between the wallpaper and the terminal interface. The article details the steps for installing and configuring Pywal, making it accessible to users with varying levels of Linux proficiency. The installation process begins by emphasizing Pywal's Python foundation, making it compatible with any Linux distribution that supports Python. Users are guided to install `pip3` if it's not already present, with specific instructions for Debian/Ubuntu-based systems using `sudo apt install python3-pip`. Once `pip3` is installed, Pywal itself is installed globally using `sudo pip3 install pywal`. This straightforward installation ensures that the tool is readily available across the system. Following installation, the article explains how to use Pywal to apply a new color scheme. Users are instructed to execute the `wal -i path_to_wallpaper_file` command, where `path_to_wallpaper_file` is the location of their chosen wallpaper. Upon execution, Pywal analyzes the wallpaper's colors and instantly applies a harmonized color scheme to the currently open terminal. It also sets the specified image as the desktop background, demonstrating the immediate visual impact of the utility. A key aspect addressed in the article is ensuring that newly opened terminal windows adopt the new color scheme. By default, Pywal only affects already running terminal sessions. To extend this functionality, users are advised to modify their shell's configuration file, typically `~/.bashrc` for Bash users. The article provides specific lines of code to add to `~/.bashrc`, which import the color scheme from Pywal's cache asynchronously. This modification ensures that any subsequent terminal launched will automatically use the Pywal-generated color scheme. Furthermore, the article provides instructions on how to maintain the Pywal color scheme across system reboots. Since Pywal does not persist color schemes by default after a restart, users can add the `wal -R` command to their system's startup applications. This command restores the last-used Pywal color scheme, ensuring that the terminal's appearance remains consistent with the desktop background upon every system boot. An example for Ubuntu users using the 'Startup Applications' program is included, illustrating how to add the command with a descriptive name. The article also touches upon Pywal's extensibility, highlighting its ability to customize other applications beyond the terminal. It mentions Pywal's plugin support for various tools like Vim, Emacs, Gnuplot, and CLI-Visualizer, as well as its compatibility with window managers such as i3 and Sway, and taskbars like Polybar. This broader customization capability allows users to achieve a more unified and personalized desktop experience. The article concludes by inviting user feedback and suggestions for other similar utilities to be featured in the 'Terminal Tuesday' series, underscoring the community-driven aspect of desktop customization in Linux. #LinuxTerminal #ColorScheme #Pywal #DesktopCustomization #WallpaperIntegration #ShellConfiguration #Command-LineTool

The choice between removable and traditional wallpaper often arises from past experiences with the difficult removal of traditional wallpaper. Historically, removing wallpaper was a multi-step, labor-intensive process involving scoring, steaming, and scraping. In response to this challenge, removable, or peel-and-stick, wallpaper options have become widely available over the last decade, offered by various retailers from mass-market to high-end brands, with prices comparable to traditional versions. Removable wallpaper functions like a large, durable sticker with an adhesive backing, typically made of vinyl. Installation is straightforward: peel off the backing and press it onto the wall, eliminating the need for adhesives or paste. This temporary nature makes it ideal for renters, college students, or those decorating a space for a short period, such as a nursery. It's also suitable for experimenting with trendy looks without a long-term commitment. One significant advantage is its easy removal, which can be done in minutes with minimal damage to the underlying surface, even after extended periods. However, despite its simpler installation process, proper placement can be tricky. Unlike traditional wallpaper, which allows for repositioning due to wet paste, peel-and-stick wallpaper adheres instantly. Correcting a misaligned panel requires removing the entire piece and reapplying it, which can be challenging, especially with intricate patterns or uneven walls. This can lead to stretching the paper or permanent bubbles if not handled carefully, suggesting the need for an extra roll for mistakes. Removable wallpaper is best for small projects like bookcase backs or accent walls, or for spaces that will change over time. Traditional wallpaper includes paste-the-wall and paste-the-paper varieties. Modern paste-the-paper options often skip the soaking step, allowing for direct paste application. While removable options have expanded, specialty finishes, luxury papers, or specific textures like grass cloth are predominantly found in traditional formats. The main drawback of traditional wallpaper is its permanence and the intensive removal process. This can take days, involving scoring, steaming, and scraping, often leaving behind adhesive residue or minor wall damage. This makes it less appealing for short-term decor or frequent changes, and professional removal can be costly. However, traditional wallpaper generally offers a higher quality finish and material. The wet paste during installation allows for easier adjustment and alignment, which is particularly beneficial for detailed patterns or older homes with imperfect walls. Paste-the-wall methods are often slightly easier than paste-the-paper, as they eliminate the need for a pasting table, making both accessible even for beginners. Traditional wallpaper is recommended for homeowners installing classic or high-end papers, those seeking a long-term decor solution (five years or more), or individuals undertaking larger projects like entire bedrooms. It is also suitable for older homes where walls may not be perfectly straight, as the adjustability of traditional wallpaper can compensate. Ultimately, the decision between removable and traditional wallpaper depends on the project's scope, home ownership status, and desired longevity of the decor. #RemovableWallpaper #TraditionalWallpaper #HomeDecor #InteriorDesign #DIYHomeImprovement #WallpaperInstallation #HomeRenovation #PeelAndStick #WallCoverings
