## Disable a package completely

To completely disable a package and effectively uninstalling it even if it
is part of your used layers, look for the variable
`dotspacemacs-excluded-packages` in your dotfile and add the package name
to it:

```elisp
dotspacemacs-excluded-packages '(package1 package2 ...)
```

## Disable a package only for a specific major-mode

This is done by removing the hook added by Spacemacs. For example to
remove `flycheck` support in python buffers, look for the function
`dotspacemacs/config` in your dotfile and add the following code:

```elisp
(remove-hook 'python-mode-hook 'flycheck-mode)
```

**Hint** to know the name of the major-mode of the current buffer press:
<kbd>SPC h d v major-mode RET</kbd>

## Disable company for a specific major-mode

It may be handy to disable `company` for a given mode if you plan on
configuring `auto-complete` instead. On easy way to do it is to use
the macro `spacemacs|disable-company` in the function
`dotspacemacs/config` of your dotfile. The following snippet disables
company for `python-mode`:

```elisp
(spacemacs|disable-company python-mode)
```
