A couple of questions just to confirm:

1. You do have the vim plugin installed in addition to the tmux plugin, right?
2. Have you checked for conflicting keymaps in vim as per these instructions?

Presuming neither of those resolve it, can you test out the following:

1. With vim open in the first pane (pane 0 in tmux)
2. In a split terminal pane, run ps -o state= -o comm= -t $(tmux display -p -t 0 '#{pane_tty}')
3. Share what the output is?

I'm seeing the following output, for context.

Ss   zsh
S+   vim

[ahmedsayedabdelsalam]

it's not working with me too. am using nvchad

[khalil-chermiti]

  -- No longer needed, using tmux navigation integration 

-- navigate = {
-- 	{ mode = "n", keymap = "<C-l>", action = "<C-w>l", desc = "pane left" },
-- 	{ mode = "n", keymap = "<C-h>", action = "<C-w>h", desc = "pane right" },
-- 	{ mode = "n", keymap = "<C-j>", action = "<C-w>j", desc = "pane up" },
-- 	{ mode = "n", keymap = "<C-k>", action = "<C-w>k", desc = "pane down" },
-- },

hey @alex-belost

I had my keymaps to navigate between neovim panes, I think this made a conflict with vim-tmux-navigator
if you have a similar keymaps, try removing them and check if it solves your problem

I want to mention the the above mappings didn't cause me any trouble at a certain point, this happened recently

I am using:

• tmux : 3.2a
• neovim : 0.9.5
