为上次保存的用户或默认用户配置 Lightdm (GTK) 并关注密码？

2024-5-20 • tag-icon

lightdm

我查看了手册页和配置文件，但什么也没找到（但也许我遗漏了一些东西）。我只看到很多自动登录选项。

从一些谷歌上我了解到 KDE 版本确实可以这样工作，但我想继续使用 GTK 版本。

更新

我仍然没有找到解决方案，有时我回到这个问题，环顾四周看到了一些lightdm-gtk-greeter支持主题的屏幕截图和用户列表的弹出菜单。

我肯定在配置中遗漏了一些东西或者需要安装一些软件包。

我使用的是 openbox 而不是 gnome，下面是我可怜的迎宾员的照片。

如何让它记住最后一个用户并专注于密码？

更新2

我使用的是 GNU/Debian/unstable (jessie/sid)

这里是已安装的一些详细信息lightdm*

$ dpkg -l "*lightdm*" | grep ^ii
ii  liblightdm-gobject-1-0 1.10.0-3     i386         simple display manager (gobject library)
ii  lightdm                1.10.0-3     i386         simple display manager
ii  lightdm-gtk-greeter    1.8.4-1      i386         simple display manager (GTK+ greeter)

$ apt-cache show lightdm-gtk-greeter|grep Homepage
Homepage: https://launchpad.net/lightdm-gtk-greeter

和调试日志（从桌面启动，最终我可以添加版本/var/log）

更新3

我检查了版本 1.1.6-2/stable，没有结果。

已安装accountsservice。

（目前lightdm-gtk-greeter已升级至1.8.5-1）

以下/usr/share/lightdm/lightdm.conf.d/01_debian.conf

注释掉的是来自 Debian 安装的值，我更改了它们（但似乎它们被覆盖了/etc/lightdm/lighdm.conf）

[SeatDefaults]
#greeter-session=lightdm-greeter
#greeter-hide-users=true
greeter-session=lightdm-gtk-greeter
greeter-hide-users=false
session-wrapper=/etc/X11/Xsession

也发生了变化greeter-hide-users，/etc/lightdm/lightdm.conf弹出菜单现在出现，它显示others...，用户alex是粗体的，就好像它是当前或默认的，但在弹出窗口下方仍然有用户输入文本字段，具有焦点和空（我将更新屏幕截图和测试/稍后调试日志）。

更新：（评论后）

尝试修改在/etc/lightdm/lightdm.conf:

 greeter-hide-users=true

在

 greeter-hide-users=false

似乎所有 lightdm.conf文件都需要它。您可能需要使用它 lightdm-set-defaults [OPTION...]来修复它。完整的可用选项位于文件中：（ /usr/share/doc/lightdm/lightdm.conf.gz如果已安装）。

更新

在 Debian 中，将其设置为正确的位置很重要部分 []，[SeatDefaults]在/etc/lightdm/lightdm.conf应该赢，用于lightdm --show-config查看更改的设置和文件所在位置（相对于默认值）

原文：也许你可以尝试添加这个ppa
ppa:lightdm-gtk-greeter-team/daily
并安装LightDM GTK+ Greeter 1.6.0。
看来它会自动解决你的问题你可以在这里看到。

我找到了关于这个的 ppa页Launchpad 博客文章的数量。
