在关键的电池级别上冬眠/暂停-我应该在哪里设置它从MATE GUI？

Question

我为我的笔记本买了新电池。它正在运行Ubuntu 16.04.5LTS。

这种新型电池容量正常，充电时间长:)

但我有一个小问题:当电池电量低于某个级别时，笔记本电脑就会立即关机。我记得，它通常是用旧电池挂起来的。

使用新电池，我可以手动挂起，所有与挂起相关的测试(如pm-is-supported --suspend、pm-is-supported --hibernate、pm-is-supported --suspend-hybrid)都返回0，因此支持这些操作。

要获得更多的预测结果，我已经重新设置了所有设置

gsettings reset-recursively org.mate.power-manager

因此，我的GSettings报告如下：

$ gsettings list-recursively | egrep "critical|action|low|time" | grep -i power | sort -u
org.mate.power-manager action-critical-battery 'hibernate'
org.mate.power-manager action-critical-ups 'shutdown'
org.mate.power-manager action-low-ups 'hibernate'
org.mate.power-manager action-sleep-type-ac 'suspend'
org.mate.power-manager action-sleep-type-battery 'hibernate'
org.mate.power-manager idle-dim-time 10
org.mate.power-manager info-history-time 21600
org.mate.power-manager notify-low-capacity true
org.mate.power-manager notify-low-power true
org.mate.power-manager percentage-action 2
org.mate.power-manager percentage-critical 3
org.mate.power-manager percentage-low 10
org.mate.power-manager show-actions true
org.mate.power-manager time-action 120
org.mate.power-manager time-critical 300
org.mate.power-manager time-low 1200
org.mate.power-manager use-time-for-policy true

在/etc/UPower/UPower.conf中，我有默认值：

$ cat /etc/UPower/UPower.conf | grep -v ^# | egrep "Critical|Low|Action|Time"
PercentageLow=10
PercentageCritical=3
PercentageAction=2
TimeLow=1200
TimeCritical=300
TimeAction=120
CriticalPowerAction=HybridSleep

MATE Power Management Preferences (mate-power-preferences)没有设置关键电池级别的GUI元素：

我应该将hibernate或MATE GUI挂起的关键电池级别设置在哪里？通过GSettings或Dconf改变值会改变UPower.conf中的值吗？在关键的电池水平上，我还应该在哪里设置动作？

2.我的系统上没有安装其他类型的TLP。3.我重新安排了所有的设置，没有运气。今天我问了关于Ubuntu-Ubuntu。社区的问题。

Answer 1

我仍然找不到GUI解决方案来解决我的问题。所以我转向了半GUI解决方案。

我使用其他电池电平指示器解决了这个问题--它被命名为fdpowermon：

描述: ACPI fdpowermon笔记本电脑的简单电池电源监视器是一个简单的perl脚本，它在与freedesktop.org规范兼容的系统托盘中安装一个图标。每隔三秒，fdpowermon就会打电话给acpi，找出当前的电池电量。它将acpi命令的输出设置为工具提示文本，并将酌情更新已使用的图标。此外，当电源达到给定级别时，fdpowermon还可以选择性地调用perl子程序。但是，默认情况下不提供或启用此类子程序。

所以我已经安装好了

sudo apt-get install fdpowermon

并为此应用程序创建了配置文件夹：

mkdir -p ~/.config/fdpowermon/

在这里放了两个文件：

1.带有修改主题(在discharging数组中注意到第三个元素20:battery-low.png，它将用于Perl脚本中的挂起)：

cat << \EOF > ~/.config/fdpowermon/theme.cfg 
[mytheme]
steps = 8
dir = /usr/share/icons/oxygen/22x22/status
# The below line makes fdpowermon not show an icon when the power is
# connected and the battery is completely full. This is by design,
# because that's how the author likes to use the software, and he is of
# the opinion that it's easier to ship software configured just the way
# he likes it rather than to have to reconfigure things.
#
# Requests are often made to change this default. This will not happen,
# but it's an easy change: just change the last entry in this "charging"
# configuration so that it says "100:battery-charging.png" rather than
# "99:battery-charging.png", and you're done!
charging = 0:battery-charging-low.png, 10:battery-charging-low.png, 20:battery-charging-caution.png, 30:battery-charging-caution.png, 50:battery-charging-040.png, 70:battery-charging-060.png, 90:battery-charging-080.png,100:battery-charging.png
discharging = 2:battery-missing.png:battery-low.png,10:battery-low.png, 20:battery-low.png,30:battery-caution.png,50:battery-040.png,70:battery-060.png,90:battery-080.png,100:battery-100.png
EOF

2.带有dbus挂起操作的Perl脚本文件：

cat << \EOF > ~/.config/fdpowermon/theme.pl
# Copy this file to ~/.config/fdpowermon/theme.pl.
#
# If you don't like the 'default' theme, define a new one by copying
# /etc/fdpowermon/theme.cfg to ~/.config/fdpowermon/theme.cfg and
# renaming/adjusting the 'default' theme there to something new.
# Don't forget to replace "default" below with your new theme name.
#
# See the manpage fdpowermon(1) for full details on what you can do
# here.

# define a suspend action
sub suspend {
    system("dbus-send --print-reply --system --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.Suspend boolean:true");
}

# initialize our theme, from /etc/fdpowermon/theme.cfg or
# ~/.config/fdpowermon/theme.cfg
my $theme = fdpowermon::theme::get_theme("mytheme");

# on the discharge event for the lowest element in the list of steps (0 = first
# in the index, "d" for discharge), call the "suspend" sub defined above
$theme->set_event( 2, \&suspend, 'd' );
EOF

( DBus挂起命令来自这个伟大的答案)。

最后我已经禁用了MATE Power Manager电池指示器

gsettings set org.mate.power-manager icon-policy 'never'

并创建了自动启动桌面文件，将fdpowermon显示在托盘中：

mkdir -p ~/.config/autostart

cat << EOF > ~/.config/autostart/fdpowermon.desktop 
[Desktop Entry]
Type=Application
Exec=fdpowermon
Hidden=false
X-MATE-Autostart-enabled=true
Name[en_US]=fdpowermon
Name=fdpowermon
Comment[en_US]=
Comment=
EOF

因此，我在托盘中有一个漂亮的电池图标。

至

和

系统自动挂在20%的电池水平(该级别是可配置的，但我的新电池似乎报告的低值错误)。

Answer 2

GUI方法

出发地：在Linux 18肉桂中改变关键电池级别和动作您可以使用以下方法安装dconf-editor：

$ sudo apt-get install dconf-editor

然后转到org ->肉桂->设置-守护进程->插件-> power

• 默认设置为( %)：
• 关键电池动作: hibernate
• 关键:2
• 行动:2
• 低: 10

锻炼要谨慎，心满意足。

原始答案和

下面的编辑

使用：

查看当前设置

$ gsettings list-recursively | grep critical
org.gnome.settings-daemon.plugins.power critical-battery-action 'shutdown'
org.gnome.settings-daemon.plugins.power percentage-critical 3
org.gnome.settings-daemon.plugins.power time-critical 300

更改您的critical-battery-action

$ gsettings set org.gnome.settings-daemon.plugins.power critical-battery-action 'suspend'

Linux配偶差异

在使用Linux时，您需要用org.gnome替换org.mate，并可能更改密钥。来自ArchWiki：

电池放电

若要禁用电池放电通知，请运行：

$ gsettings set org.mate.power-manager.notify-discharging false

然而，在Ubuntu并没有类似的情况。

查找所有匹配电源设置

若要查找所有配偶电源设置，请使用：

$ gsettings list-recursively | grep power-manager

在Ubuntu中，您可以使用：

$ gsettings list-recursively | grep plugins.power
