This article explains how to have the X server start automatically right after logging in at a virtual terminal. This is achieved by running the startx command, whose behaviour can be customized as described in the xinitrc article, for example for choosing what window manager to launch. Alternatively, a display manager can be used to start X automatically and provide a graphical login screen.

Shell profile files

Note: These solutions run X on the same tty used to login, which is required in order to maintain the login session.
  • For Bash, add the following to the bottom of ~/.bash_profile. If the file does not exist, copy a skeleton version from /etc/skel/.bash_profile.
    For Zsh, add it to ~/.zprofile instead.
[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec startx
Note:
  • You can replace the -eq 1 comparison with one like -le 3 (for vt1 to vt3) if you want to use graphical logins on more than one VT.
  • X must always be run on the same tty where the login occurred, to preserve the logind session. This is handled by the default /etc/X11/xinit/xserverrc.
  • For Fish, add the following to the bottom of your ~/.config/fish/config.fish.
# start X at login
if status --is-login
    if test -z "$DISPLAY" -a $XDG_VTNR = 1
        exec startx
    end
end

Tips

  • This method can be combined with automatic login to virtual console. When doing this you have to set correct dependencies for the autologin systemd service to ensure that dbus is started before ~/.xinitrc is read and hence pulseaudio started (see: BBS#155416)
  • If you would like to remain logged in when the X session ends, remove exec.
  • To redirect the output of the X session to a file, create an alias:
alias startx='startx &> ~/.xlog'
