_Also applies to other distributions based on it, how do you change
|
|
the display manager, aka login screen._
|
|
|
|
- `--needed` makes pacman not install packages that are already installed.
|
|
- uncommented line = line that doesn't begin with `#`.
|
|
- to change DM you don't need to reboot, you can also
|
|
`sudo systemctl stop olddm` and `sudo systemctl start newdm`, but this
|
|
logs you out.
|
|
- my personal recommendation is using LightDM if it works for you,
|
|
otherwise sddm. I personally use LightDM, because sddm is missing
|
|
support for `sudo passwd -de user` [sddm/sddm#472](https://github.com/sddm/sddm/issues/472)
|
|
|
|
## LightDM gtk greeter
|
|
|
|
- `sudo pacman --needed -S lightdm lightdm-gtk-greeter accountsservice numlockx`
|
|
|
|
Edit the file `/etc/lightdm/lightdm.conf` and find the uncommented line
|
|
that starts with `greeter-session=` and change it to
|
|
`greeter-session=lightdm-gtk-greeter`.
|
|
|
|
If you have keyboard with [numpad] you might want to enable Num Lock by
|
|
default by finding the uncommented line starting with
|
|
`greeter-setup-script=` and changing it to
|
|
`greeter-setup-script=/usr/bin/numlockx on`. If there isn't uncommented
|
|
line anywhere in the file, just uncomment one or add it under the commented
|
|
line.
|
|
|
|
Then enable it by running `sudo systemctl enable -f lightdm` and reboot.
|
|
|
|
## sddm
|
|
|
|
- `sudo pacman --needed -S sddm`
|
|
|
|
SDDM is simple display manager for all desktop environments and is
|
|
successor of KDM which is the KDE Display Manager.
|
|
|
|
To create a config file and enable it for next reboot:
|
|
|
|
```
|
|
sddm --example-config | sudo tee /etc/sddm.conf
|
|
sudo systemctl enable -f sddm
|
|
```
|
|
|
|
The lines you might want to change are the one starting with `Nucmlock=`
|
|
and I recommend changing it to `Numlock=on` if you have the [numpad]. The
|
|
other line starts with `Current=` and is used to select the current theme.
|
|
Available themes can be seen with `ls /usr/share/sddm/themes`.
|
|
|
|
KDE users might also want to install `sddm-kcm` which gives GUI
|
|
for controlling sddm.
|
|
|
|
## gdm
|
|
|
|
- `sudo pacman --needed -S gdm`
|
|
|
|
The last display manager I am mentioning is the Gnome Display Manager and
|
|
is only for Gnome users and I am not so familiar with it and I believe
|
|
using it is just `sudo systemctl enable -f gdm`.
