IntroDisplay Managers are provided for a login screen, which protects your desktop from unauthorized users. Display Managers all provide their own styles, and different types of skin support. Their system resource requirements vary.
Note: This installation guide is assuming you are already using the default Lightdm Display Manager.
Display Manager OptionsTo change the default DM from lightdm to the one of your choice you need to follow to simple steps:
- install the one you want
- use systemd to remove the entry from lightdm end enable the new one to start on bootup
SDDM (Recommended for KDE):
sudo pacman -S sddm sddm-kcm sudo systemctl -f enable sddmMore info at the Arch-Wiki SDDM sddm-kcm is integrating sddm settings into plasma native settings, where you can configure default settings.
GDM (Recommended for GNOME):
sudo pacman -S gdm sudo systemctl -f enable gdmMore info: GDM There is no GUI tool to configure GDM settings aviable, as GNOME do not provide any basics for this. You can change background with a hack provided in the Arch-Wiki: GDM-background-hack After running GDM (native DM for GNOME) you are able to use all lock- and power-settings inside gnome-control-center. Reboot Your System: After installing and enabling a display manager, reboot your login system. You should now see the newly installed display manager's login screen.
Side Note:You do NOT need to remove (uninstall) lightdm and light-locker as it will not run anymore, and if you keep it, t will be at hand if you get problems with enabled DM! If you want to uninstall you will loose also the meta packages what can cause inconvenience, if there come some major updates to the installed DE (Desktop Environment), this will not harm your system as long as you have this in mind!
LightDM - change the greeter (not the DM!)The default DM for Antergos can also run with different greeters, this is not changing the DM it will only give another style to LightDM.
- lightdm-gtk-greeter - with lightdm-gtk-greeter-settings tool to configure it comfortable
- slick-greeter - what can be configured with lightdm-settings
- deepin-session-ui - the lightdm greeter for deepin desktop
- lightdm-kde-greeter - the lightdm greeter for kde/plasma
sudo nano /etc/lightdm/lightdm.confand change the line: greeter-session=lightdm-webkit2-greeter To fit the greeter you want to use: greeter-session=lightdm-gtk-greeter greeter-session=lightdm-slick-greeter greeter-session=lightdm-deepin-greeter greeter-session=lightdm-kde-greeter Save the file with [Ctrl + X] restart lightdm to see that all is working:
sudo systemctl restart lightdmNow you can configure style as you want with the given tools.
Multiple screen arrangementTo get dual/multi Monitor/Display setup working for slick-greeter we need to edit /etc/lightdm/lightdm.conf and create a xrandr script to make this working:
[SeatDefaults] greeter-setup-script=/etc/lightdm/display_setup.shneeds to be added at the end of the file. Now we are going to create the script: Open Arandr (if not installed do it: sudo pacman -s arandr) Arandr is mostly self explanatory: setup your displays as you need it. Save the file to your home with the name: display_setup.sh and close arandr. Open a terminal, move the script to the right place, make it executable and restart lightdm:
sudo mv display_setup.sh /etc/lightdm/display_setup.sh sudo chmod +x /etc/lightdm/display_setup.sh sudo systemctl restart lightdmThat should work, if not you may need to reconfigure display setup and startover from "Open Arandr ..."
