在登录屏幕上打开numlock。GDM

Question

GDM正在关闭numlock键。

我试过以下几点：

a) installing numlockx and inserting following lines at /etc/gdm/Init/Default
if [ -x /usr/bin/numlockx ]; then
    /usr/bin/numlockx on
fi

b) Using setleds +num, but it corrupts the numlock state.

当我重新启动系统或gdm.service时

Numlock becomes on at boot
Numlock turns off at login screen[GDM]
Numlock again turns on after login. [ KDE / GNOME ]

如何确保numlock始终处于登录状态(gdm)。

Answer 1

按照@don_crissti的提示，我成功地在gdm登录屏幕上启用了numlock，如下所示：

sudo su #become root
su gdm -s /bin/sh #become gdm user with a shell
#do the work i don't 100% understand
export $(dbus-launcher) 
GSETTINGS_BACKEND=dconf gsettings set org.gnome.settings-daemon.peripherals.keyboard numlock-state on
exit #drop back to root user
systemctl restart gdm #restart gdm
