How do I script changing from the light mode to the dark mode? In it GUI I do this: preferences>profiles>Unnamed>Colors>Bultin-in schemes (here I choose either black-on-white or white-on-black.

As far as I know, there is no config file. I use Ubuntu 22.04LTS Desktop and have no /org in my filesystem. How might I automate the process of changing the color scheme scripting the whole process with dconf or similar tools? The goal is to run the script via cron that changes from black-on-white to white-on-black at 2pm and vice versa at 7am.

I already know how to launch gnome-terminal with desired settings saved in a profile, e.g. gnome-terminal --profile=dark. This is not what I want to achieve because I want the already opened windows to change the color scheme.

    Did you look under /org/gnome/terminal/legacy/profiles:/ in dconf?

    I am not talking about any /org directory. I am talking about the dconf key path. Please, try dconf dump /org/gnome/terminal/legacy/profiles:/

Please, use the command

dconf dump /org/gnome/terminal/legacy/profiles:/

and find the relevant "profile id" that has visible-name='Unnamed'.

Using the command dconf write key_path new_value, you can change the values of the following keys:


e.g. changing to dark theme:

dconf write /org/gnome/terminal/legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/background-color "'#000000'"
dconf write /org/gnome/terminal/legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/foreground-color "'#ffffff'"

where :b1dcc9dd-5262-4d8d-a863-c897e6d979b9 is your profile id.

  • dconf dump /org/gnome/terminal/legacy/profiles:/ gave me this [:b1dcc9dd-5262-4d8d-a863-c897e6d979b9] background-color='rgb(255,255,255)' font='Monospace 21' foreground-color='rgb(0,0,0)' use-system-font=false use-theme-colors=false This Unnamed profile is not a profile that I created, it is on every Ubuntu Desktop installation. b1dcc9dd-5262-4d8d-a863-c897e6d979b9 seems to be its id. I figured out how to do this manually from dconf-editor but I need a solution that is non-interactive and can be run as a script via cron.

    Use the dconf write key_path new_value command in a script. Please, note that these values are per user, so your cron script should be run from the current user.
