Не могу включить gdm3 после руководства по удалению KDE из ubuntu

Каждый раз при запуске мне приходится нажимать ctrl + alt + f3 и вводить что-то вроде

sudo systemctl start gdm3

если я этого не сделаю, то мой компьютер застрянет на логотипе bios и больше ничего.

Это руководство, которому я следовал https://trendoceans.com/how-to-remove-the-kde-plasma-environment-in-ubuntu/

когда я пытаюсь

sudo systemctl enable gdm3

я получаю

Synchronizing state of gdm3.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable gdm3
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.

edit: I found the fix which was sudo dpkg-reconfigure gme3 thanks person on reddit
