company-mode no popup graphics at completion-at-point

Question

I tried to install company and lsp on running on Emacs v28.2 on 5.4.240-1-MANJARO for a handful of languages. Most of the stuff works fine, flycheck, linters,lsp-connection, the popup completion with added documentation. Then i reproduce the config on a other system, but the completion has no more graphic and information in the popup.

On other systems there is the popup more visual informative:

On both Systems lsp-describe-session points out to ruff and jedi.

The installed related packages are quite similare and load via use-package :

• all-the-icons-*
• company
• company-quickhelp
• flycheck
• lsp-jedi
• lsp-mode
• lsp-treemacs
• lsp-ui

can't point out where the problem lays.

EDIT:

The code for downloading company via use-package

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))
(add-to-list 'package-archives '("elpa" . "https://elpa.gnu.org/packages/"))
(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(eval-and-compile
  (setq use-package-always-ensure t ; get rid of the :ensure t key
        use-package-expand-minimally t))

(use-package company
  :config
  (global-company-mode t)
  (setq company-idle-delay 0.1)
  (setq company-minimum-prefix-length 2)
  ; (setq company-tooltip-align-annotations t)
  (setq company-tooltip-offset-display 'lines)
  (setq company-tooltip-flip-when-above t)
  (define-key company-active-map (kbd "\C-n") 'company-select-next)
  (define-key company-active-map (kbd "\C-p") 'company-select-previous)
  (define-key company-active-map (kbd "\C-d") 'company-show-doc-buffer)
  (define-key company-active-map (kbd "M-.") 'company-show-location))

EDIT II:

Check list-package and see that company and company-quickhelp are still "available" but not "installed" when check it. But when i check the variable package-selected-packages it is in the list.

EDIT III:

updated all the installed packages via list-package, still no progress

EDIT IV:

start with a blank emacs and install all with my init.el and config.org new, still no graphics from company.

EDIT V:

Managed to get correct pop-up completion at other ~prog-mode~ buffers then python i use. the only problem still is the python buffer, where there is no completion at all.

EDIT VI:

I tried to manually do M-x company-capf , and the pop-up-showed up correctly in python-mode. so i think there is an issue with the automatic pop-up. I think the problem lays in the function call in python-mode, which create the popup. Where can i fix this?

Answer 1

Seemed to be a conflict with tern-mode. Tern is a stand-alone code-analysis engine for JavaScript. And I used it with its company backend. So i used it with

(add-to-list 'load-path "~/.emacs.d/tern/emacs/")
(autoload 'tern-mode "tern.el" nil t)
(autoload 'company-tern "company-tern.el" nil t)
(add-to-list 'company-backends 'company-tern)
(add-hook 'prog-mode-hook (lambda () (tern-mode t)))

I realized that when i use M-x company-diag and see that the used backend in python-mode was also company-tern. So i just bind the mode to js2-mode and not to prog-mode-hook and have now correct completion in all languages i try.
