/xresources

1. Open or create your ~/.Xresources file (or ~/.Xdefaults) using a text editor:bash
nano ~/.Xresources
Use code with caution.
2. Add the following configuration lines to set the terminal window area to a black background with light gray text:text
xterm*vt100.background: black
xterm*vt100.foreground: lightgray
Use code with caution.
(Note: Using xterm*vt100 targets just the terminal grid area. If you want the application menus to be dark as well, use xterm*background: black and xterm*foreground: lightgray instead.)
3. Save and close the file (Ctrl+O, then Ctrl+X in nano).
4. Reload the resources into your active window manager session by running:bash
xrdb -merge ~/.Xresources
Use code with caution.
