A display manager can be used to provide a login screen and start the X server. This article explains how this can be done using an existing virtual terminal.

To manually start X, startx or xinit are used. Both will execute ~/.xinitrc, which may be customized to start the window manager of choice as described in the xinitrc article.

Shell profile file

Note: This runs 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.
Note: 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.

Tips

  • This method can be combined with automatic login to virtual console.
  • 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'
