关于电源管理的问题

[xfcy]

笔记本为联想昭阳系列E40-30，intel核心显卡。系统：linux mint 17.2 内核3.16 桌面mate
问题：点击关机后系统已经关闭，但是电源灯亮，电源未关闭，只能强按电源键关闭电源。
按照网上的一些方法，在/etc/default/grub中将GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"改为GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off acpi=force apm power_off=1"并更新grub后可以正常关机了，但是开机不正常了。在logo画面显示乱码，重启后编辑grub，在Linux一行的参数中将acpi=off改为acpi=on，按crtl+x可以实现正常开机。后来使用sudo pluma /boot/grub/grub.cfg编辑了grub.cfg将152行附近的acpi=off修改为acpi=on,保存并更新grub,重启后仍然无法进入，在启动界面使用e键编辑grub,发现其中的acpi=off，没有变化为acpi=on。

请网友指点指点笔记本电脑开关机不正常的问题解决思路。

acpi=off改为acpi=on

这样改后能正常开机，能正常关机不？电源管理问题是否解决？

不说电源管理问题，修改grub2的配置要改/etc/default/grub，然后update-grub。

试了一下，果然开机正常了。关机好像也正常了。不过这个问题，还要多观察以下。

出现新的错误:modermmanager [771]:<warn> could not acquire the 'org.freedesktop.modermmanager' service name.

我华硕笔记本也是关不了机，后来把显卡驱动改为nvidia的binary驱动，问题解决了，所有有时候关机问题不仅仅是电源的问题

出现新的错误:modermmanager [771]:<warn> could not acquire the 'org.freedesktop.modermmanager' service name.

修改/usr/share/dbus-1/system-services目录下的org.freedesktop.modermmanager的名称即可。

今天重装系统后，好像该方法失效了，但是如果仅添加noacpi acpi=off似乎就是有效的。改为GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noacpi acpi=off"

1. acpi
1-1. https://en.wikipedia.org/wiki/Advanced_ ... _Interface
1-2. https://zh.wikipedia.org/wiki/%E9%AB%98 ... 5%E5%8F%A3

2. acpi 隨著 主板/晶片 的急速發展 並沒有一統的規格 所以一直是 Linux 系統頭痛的問題
通常需要安裝合適的顯卡驅動 才能解決 acpi 大部份的頭疼問題

3. 在還沒安裝合適的顯卡驅動以前 允許 使用添加 Linux Kernel Options 核心參數 的方法 來暫時應付 acpi 引起的問題
其中 最常被用的參數是 acpi_osi=linux 意思是
modifies the list of supported OS interface strings (changes the OS compatibility reported to the BIOS). Necessary on some broken BIOSes to make temperature/fan control work.

3-4. 其它跟 acpi 有關的 Linux Kernel Options 核心參數 參見
https://help.ubuntu.com/community/BootO ... el_Options

4. 添加這些 核心參數 的方法 只是 暫時解決方案
目的是 方便登入桌面 安裝合適顯卡驅動
然後 重開機時 就可以不必添加這些 核心參數
4-1. 當然 還是有 安裝合適顯卡驅動 後 還需要添加 核心參數 的案例
通常可以向顯卡驅動研發人員通報 Bug

5. Ubuntu 已經自己發展自己的 電源管理機制 未來的版本 會包含在內
