Variable customization doesn't work in terminal

[brian-schwedock]

Trying to customize a variable takes effect in windowed mode, but not in terminal (no-window) mode.

For example,

(setq monokai-background "#004d4d")
(load-theme 'monokai t)

The variable value correctly updates with setq, but the background color does not change.

I'm using emacs 27.1 and monokai-theme 20220117.1244 from MELPA.

I had the same issue when running emacs in both Alacritty and tmux. It went away in Alacritty after I had explicitly set the TERM variable in alacritty.yml. Not sure that's helpful to you, but try playing around with it.

Tmux is still ignoring the settings, but I suspect the root cause will be the same.

I do use tmux, but the issue exists just using the default terminal in Ubuntu (and with tmux too). I set TERM=xterm-256color in my bashrc, but removing it doesn't fix the issue either.

I got it working!
I'm not setting any TERM value in ~/.config/alacritty/alacritty.yml and letting it default to alacritty.

Adding the following to ~/.tmux.conf is what made it work for me:

set -g default-terminal "tmux-direct"
set -ag terminal-overrides ',alacritty:RGB'
