How to make GIMP 2.10 titlebar black

  • 772

By default, Gimp 2.10.6 in Ubuntu 18.10 uses a dark theme. However, in a vanilla Gnome session using the default Adwaita theme, or with any other light theme, the title bar is light. Is there a way to have Gimp automatically adopt a black title bar when launched?

    My new, simpler solution

    Another solution is to use Dark-Headers, a background service will ensure that your software always has a dark title bar.

    Follow the installation instructions on the Github page, and define the list of software in ~/.config/dark-headers.conf.

    Kudos to @catvitalio for developing the service.

    My original solution

    Open Gimp, and run the following command in a terminal:

    xprop -f _GTK_THEME_VARIANT 8u -set _GTK_THEME_VARIANT dark

    Then click on the Gimp window. Its titlebar will become dark.

    Unfortunately you have to do this each and every time you open Gimp. I am sure there must be a way to run this command via a Bash script so that it happens automatically. The following bash script should automate this:

    #!/bin/bash
WINTITLE="GNU Image Manipulation Program"
APP="flatpak run org.gimp.GIMP"
$APP &
until [ -n "$(wmctrl -l | grep "$WINTITLE")" ] ; do : ; done 
WINID=$(wmctrl -l | grep "$WINTITLE" | awk '//{print $1}')
xprop -f _GTK_THEME_VARIANT 8u -set _GTK_THEME_VARIANT dark -id $WINID

    You would then just modify your menu entry to launch the bash script, rather than directly launching Gimp.

    You can use the MenuLibre tool to modify menu entries easily.
