10. How Do I Prevent LightDM from Autostarting and How Do I Manage It Manually?
To prevent LightDM from autostarting, run the command sudo systemctl disable lightdm. You can then start it manually whenever needed with sudo systemctl start lightdm. To re-enable autostart, use sudo systemctl enable lightdm.
- Disable autostart:
sudo systemctl disable lightdm- Start manually:
sudo systemctl start lightdm- Re-enable autostart:
sudo systemctl enable lightdm- Check status:
systemctl is-enabled lightdmIf you encounter issues re-enabling LightDM, reinstall it:
sudo apt install --reinstall lightdmThis allows you to control when the display manager starts, which can be useful for servers that do not require a graphical interface at all times.
11. Why Avoid Installing Specific Desktop Environment Metapackages Directly?
Avoid installing specific desktop environment metapackages directly (e.g., lxde, xfce4, mate-desktop-environment, plasma-desktop, unity, gnome) because they may install packages that are no longer preferred by Ubuntu flavors. For example, lxde installs wicd as a recommendation, while most flavors now use network-manager and network-manager-gnome.
Instead, use the -core metapackages or the full desktop metapackages as described earlier. This ensures that you get a consistent and up-to-date desktop environment.
12. What Should I Do If the GUI Throws Me Back to the TTY Prompt After Boot?
If the GUI throws you back to the TTY prompt after boot, simply restart the lightdm service by running sudo service lightdm restart.
