Human theme

This theme works with GTK 2.24 (with murrine/pixbuf) & GTK 3.24 & GTK 4.8..4.23, with or without compositor, with or without CSD windows, and with or without gtk3/4-classic. It works also with Qt 5.15 & Qt 6.0..6.11 & Firefox 152.

It is mainly intended for MATE desktop environment, it's not too bad with Xfce, it's experimental with Cinnamon.

Installation

To meet the truth (not required, if you can't/won't, no worries, but the truth will be far):

• remove gtk3-nocsd
• install gtk3-classic & gtk4-classic
• use Pango 1.42- or 1.51+

For Debian Testing, I provide a repository for gtk3-classic and for gtk4-classic, it also includes mate-notification 1.26 with a patch to customize notifications from theme. For Ubuntu, I provide a repository for gtk3-classic & gtk4-classic.

The following packages no longer install the metacity/marco theme (ClearlooksRe), because it is provided by marco package.

The road is long, but the way is free — we always have a choice.

Then set Human theme in Gimp/Edit/Preferences/Interface/Theme.

Known issues

MATE

If some characters are wider than others (for example clock applet versus classic main menu applet), this may be due to the DPI value in mate-appearance-properties (go to the Fonts tab, then Details). If you're using automatic detection, disable it. To solve the problem, press the minus button then the plus button above, see bug 1475.

Firefox/Thunderbird/Chromium

If font rendering is bad, try this:

cd /etc/fonts/conf.d/
sudo rm 10-hinting-slight.conf # /usr/share/fontconfig/conf.avail/10-hinting-slight.conf
sudo ln -s /usr/share/fontconfig/conf.avail/10-hinting-full.conf

LibreOffice

For design of menu bar, see bug 157708.

GTK 3

For better results, use gtk3-classic.

GTK 4

For better results, use gtk4-classic.

If font rendering is bad, try to add in ~/.config/gtk-4.0/settings.ini:

[Settings]
gtk-font-rendering=manual
gtk-hint-font-metrics=1
gtk-xft-hintstyle=hintfull
gtk-xft-antialias=0
gtk-xft-hinting=1

GTK 5

From migrating guide: non-standard CSS extensions are going away [...] @define-color should be replaced [...] the color functions can all be replaced by combinations of calc() and color-mix().

I think it would be nice to create a patch to fix this GTK regression.

Qt 5 & 6

For Qt, install GTK platform theme and GlobalQSS style plugin. But sadly, box-shadow and multiple background gradients are not supported, border-radius is not fully supported...

On Fedora with Qt 5, the GTK 3 platform theme (qt5-qtbase-gui) works better than on Debian (qt5-gtk-platformtheme), but the fonts remain blurry, see bug 2459509.

Xfce panels

Unfortunately, the border cannot be removed, see forum.
When a window is maximized, the window bottom border color is wrong and there is an offset of 1px.

Windows shadow

With window compositor, the window/dialog/menu shadow can't be removed or configured.

Customize

For GTK, use ~/.config/gtk-3.0/gtk.css and ~/.config/gtk-4.0/gtk.css files.

For Qt, with GlobalQSS, use ~/.config/qt5/qt.qss and ~/.config/qt6/qt.qss files.

Dev

To restore notifications from nm-applet, run:

gsettings reset org.gnome.nm-applet disable-connected-notifications
gsettings reset org.gnome.nm-applet disable-disconnected-notifications
gsettings reset org.gnome.nm-applet disable-vpn-notifications
gsettings reset org.gnome.nm-applet disable-wifi-create
gsettings reset org.gnome.nm-applet suppress-wireless-networks-available
gsettings reset org.gnome.nm-applet show-applet

To enable GtkInspector via Ctrl+Shift+I / Ctrl+Shift+D, run:

gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true
gsettings set org.gtk.gtk4.Settings.Debug enable-inspector-keybinding true

Run AWF with screenshot on theme reload:

awf-gtk2 -s ~/2.png
awf-gtk3 -s ~/3.png
awf-gtk4 -s ~/4.png
awf-qt5 -s ~/5.png
awf-qt6 -s ~/6.png

Run Entr to send the SIGHUP signal when files change to reload theme:

ls ~/.themes/Human*/gtk-2*/gtkrc | entr killall -s SIGHUP awf-gtk2
ls ~/.themes/Human*/gtk-3*/*.css | entr killall -s SIGHUP awf-gtk3
ls ~/.themes/Human*/gtk-4*/*.css | entr killall -s SIGHUP awf-gtk4
ls ~/.themes/Human*/qt5/*.qss | entr killall -s SIGHUP awf-qt5
ls ~/.themes/Human*/qt6/*.qss | entr killall -s SIGHUP awf-qt6

Run ImageTragick to create the diff image:

killall -q eom
rm -f dif.png
compare -fuzz 1% -compose src -highlight-color blue -lowlight-color none 2.png 3.png dif.png
composite dif.png 2.png dif.png
eom dif.png &

Run colors.sh to update colors. See also technical information. For any issue and pull request, please add before/after screenshots.
