    Disable GUI on Ubuntu 19.04

    Hi All
    What is the way to (only disable GUI) a t boot on ubuntu 19.04?

    I have tried modify grub:

    Code:
    sudo vi /etc/default/grub
    Code:
    #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    comment it and

    add

    Code:
     GRUB_CMDLINE_LINUX_DEFAULT="text"

    Code:
    sudo update-grub
    In union with:
    Code:
     systemctl enable multi-user.target
    But the system returns:

    The unit files have no installation config (WantedBy=, RequiredBy=, Also=,
    Alias= settings in the [Install] section, and DefaultInstance= for template
    units). This means they are not meant to be enabled using systemctl.

    Possible reasons for having this kind of units are:
    • A unit may be statically enabled by being symlinked from another unit's
    .wants/ or .requires/ directory.
    • A unit's purpose may be to act as a helper for some other unit which has
    a requirement dependency on it.
    • A unit may be started when needed via activation (socket, path, timer,
    D-Bus, udev, scripted systemctl call, ...).
    • In case of template units, the unit is meant to be enabled with some
    instance name specified.

    After reboot nothing is changed (gui start regulary)

    Thanks

    I think you have to do:
    Code:
    sudo systemctl set-default multi-user.target

    Thanks for the nice tip.
    When in text mode you can start the GUI with startx.
    BUT avoid sudo startx .
    If you do that some files in your home directory are changed to owner root.
    And you can no more log as a normal user
