I am struggling a little bit with this issue I'm having with Nemo in Linux Mint (I just upgraded to 17.3 but this is happening since 17.1). In brief, I accidentally removed some shortcuts from the "My computer" section in the left sidebar of nemo as a user. I tried to restore them, nbut apparently I can't add icons to that tab, nor drag them from the "bookmark" section to the "My Computer" one. If I start nemo as root, I can add, remove, drag and drop icons in that tab, but of course the changings does not apply to the "user" version. Moreover, I tried to perform a clean install of nemo after purging it, but unsuccessfully. Can someone explain me where th configuration file of this sidebar are located and hot to delete them, or set their permission to user in order to drag and drop correctly into that tab? Alternatively, is there a "real" way to clean install Nemo and only Nemo without touching the other GTK features? Thanks a lot for your time, any help is really appreciated!

So I am using Arc as my GTK theme, and applied it like this [Settings] gtk-icon-theme-main=Arc gtk-theme-name=Arc gtk-application-prefer-dark-theme=true in `~/.config/gtk-3.0/settings.ini` To enable it for GTK2, I did this: gtk-theme-name="Arc" gtk-icon-theme-name="Arc" gtk-application-prefer-dark-theme="true" in `~/.gtkrc-2.0`. However, gimp and some other applications (I assume they are GTK2) are light.. Others have correctly been given the Arc Dark theme and the icon-theme as well.. How do I enable the dark-mode for GTK2?

I have changed general font size for gtk-2 applications by adding this to my gtkrc file: gtk-font-name = "Sans 16" this also affected the text size in the application "dock", or however it is called, in the panel: Now even the text "New Tab - Chromium" does not fit there anymore. Can I selectively only change the text size in the application dosck, while leaving the general gtk-2 test size ? I am using openbox and fbpanel.

To enable traditional scrollbars with scroll buttons in GTK3 applications I have added the file ~/.config/gtk-3.0/gtk.css with the content scrollbar { -GtkScrollbar-has-backward-stepper: true; -GtkScrollbar-has-forward-stepper: true; } scrollbar slider { border: 0; border-radius: 0; min-width: 15px; min-height: 15px; } The first screenshot below shows the result in the GTK3 application Pluma. How do I get the same kind of scrollbar in GTK2 applications like PCManFM in the second screenshot below? **Edit 2020-08-13**: I have tried the suggestion in How do I get a bigger static scrollbar... but it makes no difference to the file browser PCManFM which still has the narrow scrollbar as shown in the second screenshot below. **Edit 2020-08-18**: Following Miloš Pavlović's suggestion below changes the scrollbar in GTK2 applications but the scrollbar has no steppers and the slider looks really strange, see the third screenshot below. **Edit 2023-07-19**: After installing Debian 12 I have been digging a bit deeper into the problem. Correct stepper arrows can be achieved by commenting out the following lines in /usr/share/themes/Adwaita/gtk-2.0/main.rc: image { function = ARROW detail = "vscrollbar" } image { function = ARROW detail = "hscrollbar" } Here is a screenshot with the following settings in ~/.gtkrc-2.0: gtk-theme-name = "Adwaita" gtk-icon-theme-name = "Adwaita" style "TraditionalScrollbar" { GtkScrollbar::has-backward-stepper = 1 GtkScrollbar::has-forward-stepper = 1 GtkScrollbar::slider-width = 16 GtkScrollbar::stepper-size = 16 } class "GtkScrollbar" style "TraditionalScrollbar" The remaining questions are how to 1. make the scrollbar solid (not hollow) 2. make the scrollbar fill out the trough and 3. make the scrollbar have sharp edges (not rounded).

Xfce 4.10; Gtk 2.24.25 For example, zenity --question invokes an austere zenity question dialog window with default verbiage and two buttons, as expected. But, with focus on said window, pressing the **Tab** key does not visually appear to rotary the internal focus (as evidenced by a faint, dashed rectangle) through either of the two buttons. This just started happening recently and I've been unable to find a solution - any ideas for smarter searches appreciated!

Below is a screenshot from Chromium browser, running in Razor-Qt desktop, In other DEs, the cursor is just normal, but here you can see it becomes a big X, anyone know how to fix that? The cursor theme is not broken, as it works for KDE4 and XFCE4 P.S That happens to all GTK apps, Qt app works fine

I used sudo apt-get remove gtk2.0 command wrongly. Now, I don't know how to fix my problem.

I am trying to add a GTK window in PAM module. It works from my test pam app but doesn't work during desktop login or unlock. I see another unanswered question here - https://stackoverflow.com/questions/59011871/gtk-pam-module-not-showing-on-login Wondering whether this is possible? If not then what is the approach to integrate / customize the login UI (gnome-screensaver, gdm-password) and let my PAM do the authentication.

I was trying to install pcsx 1.10 from source. After the configure step, make was executing until Utils.hpp:31:21: error: gtk/gtk.h: No such file or directory In file included from About.cpp:54: Utils.hpp:31:21: error: gtk/gtk.h: No such file or directory Then another one million of errors showed up. The file gtk.h is already present on: /usr/include/gtk-2.0/gtk/gtk.h Tried another time, this time changing the configuration to include the environment variables made to detect gtk files: ./configure --prefix=/media/34GB/Arquivos-de-Programas-Linux/Pcsx-df-1.10/ --enable-nautilusburn=false GTK2_CFLAGS=/usr/include/gtk-2.0/ GTK2_LIBS=/usr/lib/gtk-2.0/ This time the compilation process terminated with: /usr/bin/ld: /usr/lib/gtk-2.0/: No such file: File format not recognized collect2: ld returned 1 exit status Any suggestions?

I have the goal to compile a gtk version, so I can compile Gimp manually. This is necessary because I use Gimp 2.6, and newer distros only use 2.8 or newer. So I decided to manually compile and old gtk so to be able to compile a gimp 2.6.x. After an effort that it is even difficult to express in words to be able to compile all the GTK required libraries (with included most of the X library stack), I saw my effort being frustrated by broken compilation attempt with Pango. GTK requires Pango with X support enabled. And I tried to do so, however, during the make process of Pango compilation (1.8.2 or 1.20.5) with support to X enabled, it generates endless messages like. For instance with pango 1.20.5 I used these commands before make: ./configure --x-libraries=/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/lib/ --x-includes=/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/ PKG_CONFIG_PATH=/media/34GB/Arquivos-de-Programas-Linux/Fontconfig-2.4.0/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Freetype-2.2.1/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Glib-2.14.6/lib/pkgconfig/ XFT_CFLAGS=/media/34GB/Arquivos-de-Programas-Linux/Xft-2.1.12/include/ XFT_LIBS=/media/34GB/Arquivos-de-Programas-Linux/Xft-2.1.12/lib/ with apparently worked fine. However during compilation (make) I received endless error messages. SOme of these > ../pango/pango-layout.h:253: error: expected declaration specifiers before 'PangoLayoutRun' > > /usr/include/_G_config.h:31: error: storage class specified for parameter '_G_fpos64_t' > /usr/include/stdio.h:675: error: storage class specified for parameter 'ungetc' > ../pango/pango-modules.h:31: error: storage class specified for parameter 'PangoMap' The error messages are nearly endless. However, the compilation works fine without asking for X and xft support. The question is.........what can I do? Testing newer pango versions and hoping one works? Trying a newer gtk that might not require Pango with X support enabled?

I am having some minor trouble with SeaMonkey 2.49.1 on Linux (Manjaro 17.1.1 KDE). SeaMonkey isn't affected by my Gtk font settings. Instead it uses a really thin and barely legible font. It is the only Gtk (both Gtk2 and Gtk3) program on my system affected by this, and it affects both the official Gtk 3 build, and a custom Gtk 2 build I finished compiling. For comparison (top to bottom: Gtk2, Qt5, Gtk3, SeaMonkey): https://ibb.co/j6SODb " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy">

I want to install Qogir theme on Xfce (I'm using Debian). I've downloaded and extracted the files in the _~/.local/themes_ directory, then went to Appearance and selected Qogir in the list of "styles" (sorry if the words doesn't match precisely since my interface is in french). I've also chosen Qogir for the window theme (the "decorations"). This works, as well as the icons I've downloaded. However the content of the windows doesn't change, and instead of looking very Qogir flat design, it's looking like really old design. I've read that Xfce is using GTK2 for the rendering of some applications, and I've read in the Xfce doc that : >A GTK+ theme is the theme of the toolkit (buttons, textfields, etc). Most of the GTK+ themes need their own theme engine, make sure you have that theme engine installed with the same prefix as the GTK+ toolkit. So I installed the engines with apt, and nothing changed but I guess that's normal since the doc says the engine should have the same prefix as the GTK+ toolkit. My questions are : what exactly is the GTK+ toolkit ? It that my Qogir theme ? How can I find those installed GTK2 engines to modify their prefix ? And... how can I modify the prefixes ? Thanks a lot for your help!

Xfce4 was originally in GTK2. But after a recent upgrade to version 4.12, I find it is halfway GTK2 and halfway GTK3. Which applications are currently ported to GTK3 and which are currently not yet?

My Firefox is not displaying things correctly. 1. Bars on websites for me to enter text in are usually displayed in black, entered text is dark gray-ish (i can view it when i mark it, but that's only a temporary workaround) 2. Equations on Wikipedia are rendered in light gray for some reason. I recently updated to Firefox Quantum, hoping that this would solve the issues (it didn't). My machine is running Manjaro 17.1pre2 Hakoila, my desktop environment is Xfce and the window manager i am using is Xfwm with the Adapta-Nokto theme. My GTK theme is Vertex-Maia-Dark [GTK2].

I'm using **Linux Ubuntu 14.04 LTS** installed on **VirtualBox** using mini .iso and trying to make my own distribution based on it. I know, support of that version ends in 3-4 months, I'll update it on my new computer. Of course, I'm developing desktop environment, taskbar, etc. But I don't know how to customize the **message dialogs** (error, warning, question and information) of it. Now I want to replace the shell of these dialogs with my own version. I'm using "**Openbox**" as base for desktop environment. And **x11** and **GTK** is installed on it. Are these message dialogs related to GTK or X11? *(Note : This is my first question in StackExchange)*

I prefer the user interface of the font-selection dialog of GTK2 to that of GTK3. How can I make GTK3 applications use the GTK2 dialog? EDIT: Unfortunately, Gnome doesn't let me take screenshots of the dialogs, so I am posting links. The font-selection dialog of GTK2 is on top of this page , whereas the font-selection dialog of GTK3 is on top of this page . I prefer the interface of the former dialog, so I would like all applications to use it instead of the latter dialog whenever I need to select a font.

I know how to set font for GTK+3 programs from the command-line, namely by editing the right-hand side (RHS) of ~/.config/gtk-3.0/settings.ini's font line: gtk-font-name=Font Awesome 5 Free Regular likewise to set the GTK+ 3 font I'd edit the RHS of: gtk-theme-name=Qogir-win-light (these lines are taken from my settings.ini file) but I do not know how to do so for GTK+ 2 programs.

I've recently updated a few programs to gtk3 (deadbeef gtk3 plugin, pcmanfm-gtk3, l3afpad) and there's one thing that's really been bugging me: Why is the Statusbar thrice the height of the gtk2 version? It's clearly not because there's more information or a bigger font - the text is the same for both versions, it's just a 10 px margin for the statusbar in gtk3. So I thought "hey, gtk3 has some nice CSS, maybe I can tweak that with gtk.css oder settings.ini" - turns out that nah, not really. Any stuff in gtk.css like GtkStatusbar { margin:0px; margin-top:0px; margin-bottom:0px; } doesn't do anything, sadly. So I tried playing around with GtkInspector in pcmanfm. When I select the whole Statusbar element (you have to select the whitespace between the left and the right labels, only 10 px wide) and I check the properties, I see theres a 10 px value for all margins defined for GtkWidget (except for bottom and top, those are 6). Now if I doubleclick that value and set "all margins" to 0 it immediately gives me a gtk2 statusbar - rejoice! So I know it is possible, but I just haven't found a way to get that into gtk.css. I got desperate enough to try: GtkWidget { margin:0px; margin-top:0px; margin-bottom:0px; } but I didn't really expect it to work - so of course it didn't. I've also tried searching for solutions online, but I've only ended up with a few very specific tips to downgrade eclipse from gtk3 to gtk2 in order to save screen space or this patch to engrampa that removes those margins. Hell, it could be there's some GUI-Tool for GNOME that does this in like 5 seconds, and I've been searching for the wrong stuff all along.

I am using Debian Stretch with Openbox window manager and I am trying to set the uniform look for GTK2, GTK3, QT4, QT5 widgets. Everything went smoothly except for GTK3 that partially ignores ~/.config/gtk-3.0/settings.ini file which looks like this *(I used Lxappearance to modify it)*: gtk-theme-name=Breeze gtk-icon-theme-name=breeze gtk-font-name=Roboto Medium 10 gtk-cursor-theme-name=breeze_cursors gtk-cursor-theme-size=0 gtk-toolbar-style=GTK_TOOLBAR_BOTH_HORIZ gtk-toolbar-icon-size=GTK_ICON_SIZE_SMALL_TOOLBAR gtk-button-images=0 gtk-menu-images=1 gtk-enable-event-sounds=0 gtk-enable-input-feedback-sounds=0 gtk-xft-antialias=1 gtk-xft-hinting=1 gtk-xft-hintstyle=hintfull gtk-xft-rgba=rgb Option gtk-font-name=Roboto Medium 10 is completely ignored by all GTK3 applications which continue to use their default font Sans 10 while option gtk-font-name=Monospace 10 works. Other options like gtk-button-images=0 also work if I change them and restart GTK3 applications. So what can I do to be able to use Roboto font in GTK3 applications inside my Openbox window manager? Roboto font works for GTK2 applications in ~/.gtkrc-2.0. It looks like gtk-font-name="Roboto Medium 10" *(mind the quotes which should be avoided in GTK3 configuration file)*. Roboto font also works for QT4 and QT5 applications and was applied using qt5ct... So only GTK3 is making problems for Roboto fonts...

I did the following steps to install Firefox 57 on CentOS 6.5 : 1) wget http://ftp.mozilla.org/pub/firefox/releases/57.0/linux-x86_64/en-US/firefox-57.0.tar.bz2 2) tar xvjf firefox-57.0.tar.bz2 3) sudo ln -s /usr/local/firefox/firefox /usr/bin/firefox 4) firefox I get the following Error: libgtk-3.so.0: cannot open shared object file: No such file or directory Couldn't load XPCOM. Is it possible to install Firefox 57 on CENTOS 6.5 ?
