I recently switched over to Xfce and really enjoy it. However, when I went in to my settings to change the appearance, the theme that I liked best was "Xfce-dusk" with one exception: The default colors for application tabs are so dark that it's hard to tell where they are. I hunted around for a little while looking anywhere I could to see where the styles for the tabs are set in the theme configuration file and couldn't find anything that looked like it would do what I need. The file I've found to define the theme was: /usr/share/themes/Xfce-dusl/gtk-2.0/gtkrc But looking through that file, I can't find anything that seems to apply. Any suggestions? Normally I'm a command-line only sort of guy and don't really know much about WMs or theming, and don't even know the terms of what I'm trying to modify, so my Google searches are coming up painfully empty. Here is a screenshot of the type of tabs I want to modify.

*Picture: Debian 12 Bookworm with Plasma 5.27 and Lightly installed from boehs's fork . Colour Scheme is called "Valo" and it's soon to be published in KDE Store / Pling.* Intended as a general guide for "***how-to-make-KDE-Plasma-applications-translucent***" for most Linux distributions while using colour schemes based on **Luwx/Lightly** . The three new options are in random order - I encourage you to try them and choose whichever the best suits your needs. ---- **Kvantum Engine** is a different approach and the colour schemes made for Lightly ***possibly are not translucent when using Kvantum***. --- **I would like to express my deepest gratitude** to **Luwx** -the original creator of Lightly - you have made something marvelous - to boehs and many others who have updated and maintained the original work - **and to creators of the new options**: **Séra Balázs** for Darkly, **ekaaty** for vinyl-theme and **taj-ny** for kwin-effects-forceblur. --- My hobby is to create transparent / tranlucent colour schemes based on Lightly - I am creator of Alpha colour scheme which is used as a reference in kwin-effects-forceblur aka *Better Blur*. My full set of colour schemes can be found in KDE Store / Pling (some old are not so good) and more are to published soon. Most of them are translucent when using Lightly based solutions. **When downloading colour schemes via System Settings' "Get new color schemes" you can find most of them with key word "lightly"**. --- If you have knowledge of how to install Lightly to a distribution not included here - please share it with us by writing an answer or a comment.

I have the following fontconfig configuration, but the font weights aren't changing as expected. I discovered that changing target="font" to target="pattern" makes it work.

Based on my research, I believe target="font" should work as well. Could anyone help me understand what might be causing this behavior?

I am a user of [Linux Mint](https://en.wikipedia.org/wiki/Linux_Mint) . One feature I often wish I had in Linux is the ability to switch between light and dark modes depending on the time of the day, as in macOS and mobile devices. I have put together the following script for switching from light to dark mode:

#!/bin/bash
notify-send "Switching to dark mode"
gsettings set org.cinnamon.desktop.wm.preferences theme Mint-Y-Dark
gsettings set org.cinnamon.desktop.interface gtk-theme Mint-Y-Dark
gsettings set org.cinnamon.theme name Mint-Y-Dark

and I have another one for the opposite direction

#!/bin/bash
gsettings set org.cinnamon.desktop.wm.preferences theme Mint-Y
gsettings set org.cinnamon.desktop.interface gtk-theme Mint-Y
gsettings set org.cinnamon.theme name Mint-Y

Currently, I run these manually when I want to switch between the two themes. Most programs respect the OS-wide theme meaning this method works surprisingly well! However, there are three problems that I would like to solve with this approach: 1. Automated switching between light/dark modes depending on the time of day (as in macOS). I tried using cron and anacron but they don't work well for this purpose. When my computer is turned on after a period of being off, I would like it to realise that the time to switch has passed and perform the mode switch (as in macOS and various mobile devices); 2. I would like my terminal (GNOME Terminal, Cinnamon default) to switch from a light theme to a dark theme (and vice versa); and 3. I would like my text editor (Emacs) to load a light/dark theme. Even getting just (1) to work would be quite nice!

When I was installing some icon-packs (from WhiteSur), I noticed that my panel/taskbar suddenly disappeared. I am using Kali Linux with I think XFCE. If it may help when I run xfce-panel--preferences. It gives me an error. "Failed to show the preferences dialog. GDBus.Error:org.freedesktopDBus.Error.ServiceUnknown: The name of org.xfce.Panel was not provided by any .service files.". If this helps in any way I created .themes and .icons folders before all of this, the second I switched the the whitesur icon pack my taskbar dissapeared.

I upgraded to plasma 5.12 and the global menus disappeared, and the entry in settings also disappeared. > **Application Style ⇒ Widget Style ⇒ Fine Tuning** I tried deleting the plasma* files from ~/.config and also the whole ~/.kde folder thinking it may be some misconfiguration, but none of this helped.

So I'm using Parrot Security OS (Mate based UI), and I accidentally change the theme, but while I switch it back, the login page's background (the small box where you chose user and enter password) change from dark to light. I've thought that the default theme might be a customized theme so I enter live mode in the installer and grab the default theme, but while I later paste it to ~/.theme the login page background doesn't changes back. How can I fix it? ### Edit: I've try to install ParrotSec on other drive and this time the login box background color change on next reboot, and I didn't even touch the appearence part. Why?

There's [a way in browsers](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme) to query if the user prefers a dark or light theme so that a website developer could adapt the website's colours according to user preference. Is there also a way to detect that on the command line? Is there a command that outputs light or dark (or some equivalent boolean-valued output indicating light or dark?)

I know how to change the icon of a file/folder on Linux (using Dolphin in my case). I know also how to change the icon of a file/folder on Windows 11, both directly in the parameters and using a desktop.ini file. I'm more interested in this second option because I want to cusomize icons on an external sotrage unit (so the drive contains the icons it needs to display, and so I need to have the system look at the relative path --on Windows at least, with these stories about varying drive letters). But when I'm done creating (and hiding) all the desktop.ini files and my folders look all pretty in Windows, and I go back to Linux... The icons are the default icons. I expected that much, so I changed the icons the Dolphin way, in the naive hope that it wouldn't beak my "Windows setup". But it did! On Windows the nice icons don't show anymore, the folders are back to default, *even though the desktop.ini are still there and unmodified!!*! This is really anoying. The exact details: there a a few folders on my drive, and the first one (Backups) looks like this: * Backups * desktop.ini * .hidden * .directory \- desktop.ini: [.ShellClassInfo] IconResource=..\.icons\ICO\Backups.ico,0 \- .hidden: System Volume Information desktop.ini \- and .directoy: [Desktop Entry] Icon=/run/media/myusername/Appendix/.icons/ICO/Backups.ico (Appendix is the label of my pendrive). So if anyone has tried this before, all help is welcome. I think I'm close but something's eluding me. I guess on the Windows side.

I am using Linux 6.0.0-kali3-amd64 on Oracle VirtualBox. But, to me the icons on the Desktop appear to be way too small. Same goes for the icons on the top ribbon. I looked up the internet but most of forums addressed the problem by increasing the scaling from 1x to 2x, which in my opinion gets too big. Is there another way around this? Any way to scale somewhere in between 1x and 2x?

I have switched from Debian with systemd to Devuan without systemd and my quality of life has much improved. Both operating systems have xfce4 as desktop environment. But I have noticed that all the color themes in Settings -> Appearance -> Style (I believe this is known as GTK+ themes?) are missing. The themes that came with standard Debian Bullseye were called: Adawaita, Adawaita-dark, High Contrast, Raleigh, Xfce, Xfce-4.0, Xfce-4.2, Xfce-4.4, Xfce-4.6, Xfce-b5, Xfce-basic, Xfce-cadmium, Xfce-curve, Xfce-dawn, Xfce-dusk, Xfce-flat, Xfce-kde2, Xfce-kolors, Xfce-light, Xfce-orange, Xfce-redmondxp, Xfce-saltlake, Xfce-smooth, Xfce-stellar, Xfce-winter. There is only one theme in the Devuan xfce4-install, and I prefer to change it to one of those that came with standard Debian. Therefore I have some questions: - Were the themes that came with Debian Bullseye contained in some package? If so, what's it called? My goal is to apt install it if possible. - If it is not possible: I noticed in the past that there were subdirectories in /usr/share/themes with names that match the labels in Settings -> Appearance -> Style on Debian Bullseye. Are these connected to the themes in Settings -> Appearance -> Style? - If I install Debian again, can I somehow move them over to Devuan by copying? - If so, how would I do it? PS: I know there are entire websites dedicated to color themes for xfce4, that's not the question.

I am using Chrome web browser on MX Linux 19.2. I installed a theme from Chrome Web store. For removing an installed theme, you have to go to settings and click on appearance. There is an option to reset to default theme. But, in Linux version, this option is nowhere. It only shows a button to shift on classic or gtk+ theme. When the theme is changed to classic or gtk, the theme installed from store is simply disabled, but not removed. How can I remove it ?

Can I hide full name of desktop objects? Long names keep appearance ugly. Is there a config file or setting for do that? I use cinnamon in linux mint.

In order to increase size I have used larger fonts (beside some other settings like toolbar icons size in Dolphin) and a global scale of 112%. This is how my panel looks for me to be comfortable with it. But Firefox tabs are too small. The fonts are OK, fallowing the system settings for font size, but tabs and buttons are not ok, global scaling seems to have no effect... This is on Fedora 34 KDE with Plasma 5.21 - KDE Frameworks 5.80.

I don't see an option for this in the System Settings option. Is it possible to do this one?

I first noticed an issue I had on Linux Mint using the mate desktop environment. I wasn't able to resolve it, so I thought that switching to a different distro and desktop would be the answer. I'm now using Antergos and the openbox desktop and I've run into the same problem once again. My icons look weird and are showing the wrong colors. They're displaying as shades of pink, red, and white. I noticed this in several areas such as the app icons in the taskbar, icons in my file manager, icons of programs like GIMP, and the window border theme previews in the LXAppearance settings. I've tried several things to try to fix or get around this. I've switched to multiple desktop environments and window managers like fluxbox, icewm, awesome, KDE plasma, and gnome. This issue remains in every single DE and WM. I've also tried changing themes and icon themes and the problem still remains. I'm out of ideas and could really use some help. This has turned my linux desktop into an ugly mess and I really don't want to continue to use it when it's like this. I've included some images of my problem below.

I am quite happy, how my kde on debian handles the theming for gtk apps like firefox or thunderbird. I usually use the breeze-dark or adwaita-dark themes. However, I use one application (moneyplex) that never looks good with my gtk theming. There are text fields that have ugly white backgrounds with light grey font color in them, where their background should be dark. So I really want to set an override theme for just that one application. I found a frequently named solution to try something like GTK_THEME=Adwaita:light moneyplex and variants of it but it does not work at all. Is there any other environment setting that will override the current gtk theme engine for one app?

For the package GeoGebra 5, the text of the menu bar looks bad, with a strange (and unwanted) font. This is the normal, good look of the menus of other programs: This behavior is new. It's happening since around one week ago. Before this issue, I was tired by a poor appearance of my desktop: it looked with an old-fashion; almost all the fonts of the desktop looked no so well. So, I followed this suggestion: https://forum.manjaro.org/t/better-font-settings-in-easy-way-xfce-and-gnome/24319 However, I didn't make the step for Qt configuration. My system works with Qt4. Maybe this is the reason for the trouble. Today, I tried with the Qt4 configuration, font substitution. However, I don't know how to manage rightly this setting. I guess that the shown font is Abydos (it appears in the Qt4 font setting window, substitution area; it's exactly the first item in my fonts list). I have tried too: - changing some options in Setting tools Appearance and Windows Manager - uninstalling (https://askubuntu.com/questions/151941/how-can-you-completely-remove-a-package , post of user2777677), deleting the geogebra and GeoGebra folders of my .config directory, and reinstalling GeoGebra 5 without fixing the issue. My system: Debian 9, Xfce, 64 bits This questions could be similar to my case: - https://unix.stackexchange.com/questions/126281/weird-bug-with-xfce4-menu-panel-font-very-small - https://unix.stackexchange.com/questions/443065/fix-for-ugly-fonts-in-programs-like-keepassxc-or-nextcloud-on-antergos-with-gnom

I wanted to create a desktop wallpaper slideshow with my own set of images as described in this answer using shotwell but faced certain problems - once photos are selected from shotwell for slideshow ; it continues using even those images which have been deleted manually from the specified folder after selection of photos - similarly when photos are added they aren't automatically picked up for slideshow In short How to set up the slideshow in such a way that photos are automatically picked or removed ?I will prefer scripts over any extra apps if possible or apps if they are from well known authentic sources .

I'd like to know if there's a way to customize the sudo password request. The default string is: [sudo] password for USER: Is there a way to change that to some other custom string, like: Insert sudo password: ? I want to clear this: I'm *not* asking how to change the password. I'm asking how to edit the terminal string that appears in the terminal when the system asks for the user password. Thank you! :)
