# GDM
|
||
|
||
From GDM - GNOME Display Manager: "The GNOME Display Manager (GDM) is a program that manages graphical display servers and handles graphical user logins."
|
||
|
||
Display managers provide X Window System and Wayland users with a graphical login prompt.
|
||
|
||
## 1.GDM auto-suspend (GNOME 3.28)
|
||
|
||
GDM uses a separate dconf database to control power management. To apply your user's power settings, copy them to GDM's dconf database:
|
||
|
||
```bash
|
||
IFS=$'\n'; for x in $(sudo -u username gsettings list-recursively org.gnome.settings-daemon.plugins.power); do eval "sudo -u gdm dbus-launch gsettings set $x"; done; unset IFS
|
||
```
|
||
|
||
where username is your username.
|
||
|
||
To only disable auto-suspend on AC, run（关闭 GDM 自动休眠功能）:
|
||
|
||
```bash
|
||
sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
|
||
```
|
||
|
||
(To also disable auto-suspend on battery, run the command with battery instead of ac.)
|
||
|
||
Restart GDM to activate your changes.
