Emacs Configuration from TuDatTr

Preface

Before installing and using emacs, emacs should be run as a daemon. This decreases the loading times of the editor enormously and enables you to return to your former emacs session at any time. To do this you first need to make sure emace --daemon is run during the start up. To access the daemonized emacs you can either run emacsclient -t to use it in the terminal or simply emacsclient if you want to use the GUI version.

(add-hook 'window-setup-hook
'(lambda ()
(if not (display-graphic-p)
(set-face-background 'default "unspecified-bg"))))
