在 gnome-control-center 的省电设置中，其中包括：

  • “不活动时屏幕变暗”切换
  • “黑屏”下拉列表

然而，“不活动时暗屏”什么也没做。只要“黑屏”不是“从不”，无论切换状态如何，屏幕都会变暗。

相反，将其设置为“从不”将始终防止变暗。

什么是“不活动时暗屏”切换应该设置？

我的电脑 10 次中有 9 次需要 ≅ 2 分钟才能关闭或重新启动。我尝试了很多事情，比如添加systemd和/或shutdown到 initcpio 钩子，但没有运气。

reboot -f永远不会挂起，所以我按照这些步骤进行调试。添加选项/proc/cmdline后变为

initrd=\intel-ucode.img initrd=\initramfs-linux.img root=PARTUUID=d596f77d-aafa-479f-ad3c-df9e7c91fc7b rw quiet systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M printk.devkmsg=on enforcing=0

和debug.sh

#!/bin/sh
mount -o remount,rw /
dmesg > /shutdown-log.txt
mount -o remount,ro /

令我惊讶的是，这大大减少了挂起的次数，但我设法在重新启动时填写了shutdown-log.txt：https ://gist.github.com/MatTheCat/99498b006651110462f3488dcb454b40

这是重新启动正常时的shutdown-log.txt ： https ://gist.github.com/MatTheCat/77f168927008bb0b886bb944d19337f1

电脑是戴尔 XPS 13 9380。

所以我不明白，因为这总是对我有用，但是在安装新的 Arch Linux 后，我总是提示 GDM 登录屏幕。

我通过 gnome-control-center 启用了自动登录（“Connexion automatique”切换）

我相信更新了/etc/gdm/custom.conf

# GDM configuration storage

[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false

AutomaticLoginEnable=True
AutomaticLogin=mathieu

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
#Enable=true

但是这个配置仍然让我在启动时进入登录屏幕。我错过了什么？我正在使用 GDM 3.30.2

这是/var/lib/AccountsService/users/mathieu的内容
