Desktop Managers

by Bryanpwo

If you don’t have automatic login enabled, the Desktop Manager is the first thing you’ll see after your system went through Grub and the kernel start-up.

Most people call it a greeter, but it’s so much more than that, it also is responsible for a smooth desktop experience. That’s why it’s key to install the Desktop Environment with the corresponding Desktop Manager.

Gnome

Gnome recommends GDM as their DM. If you installed the Gnome group, GDM is already installed, but not enabled by default. If you’re coming from the offline installer do the following:

sudo systemctl -f enable gdm

(the -f option forces to disable the already enabled one and enables the new one)

Then reboot the system and GDM will appear on your login screen.

KDE Plasma

KDE uses SDDM, to install it enter the following

sudo pacman -S sddm

Then follow the disable/enable instructions described under Gnome, replacing gdm for sddm.

Deepin

Deepin uses Lightdm, but with a customized script (DDE) to make the DM more in sync with the DE. This DDE is already shipped when you’ve installed the deepin group, you only have to change the Lightdm file to enable it.

sudo nano /etc/lightdm/lightdm.conf

And change the next line to look like this:

greeter-session=lightdm-deepin-greeter

Be careful to look for the line without the # in front of it (there’s also a line that starts with # greeter-session=) don’t change that line. After you’ve done that save and close the file with ctrl+o and ctrl+x and reboot.

Budgie

Budgie doesn’t have a specific designated DM, but since it’s recommended to install the Gnome group with this DE, you can use GDM. To enable it read the Gnome section.

Cinnamon

Cinnamon uses Lightdm, but if you want to make the DM look more like Linux Mint you can install lightdm-slick-greeter and to customize it to your liking you can also install lightdm-settings. Since both packages are in the AUR, you can use yay to install them.

After install you have to change the lightdm config file, just read the deepin section for this and change the line into this:

greeter-session=lightdm-slick-greeter

Save and close the file (see Deepin) and reboot. To customize Lightdm just open the lightdm-settings app so you can change the position of the login box and change the background picture.
