Download the ebook. Power Management. The topic of power management is often problematic. Indeed, properly suspending the computer requires that all the computer's device drivers know how to put them to standby, and that they properly reconfigure the devices upon waking.

Unfortunately, there are still many devices unable to sleep well under Linux, because their manufacturers have not provided the required specifications. The software suspend banner rallies several recent efforts to integrate reliable hibernation under Linux, on disk or in memory.

Recent kernels are relatively reliable in that regard, when used in cooperation with tools of the uswsusp package. Unfortunately the problems related to hibernation are not yet ancient history, and you should run tests on your hardware before putting too much faith in its ability to wake from suspend.

For those who want to learn more about how standby works with ACPI, Matthew Garrett has an excellent article about this in his blog.

The apmd package provides a daemon that looks for events connected to energy management switching between AC and battery power on a laptop, etc. In all other cases, ACPI should be used. More powerful and flexible, it is also more complicated to implement.

The acpid package is the counterpart to apmd for the ACPI world. When moving from one to the other, you must take care to remove the apmd package, since keeping it alongside with acpid could cause problems and vice-versa.

The graphics card driver often has a problem with standby. In case of trouble, it is a good idea to test the latest version of the X.TLP saves laptop battery power on Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it.

Nevertheless TLP is highly customizable to fulfil your specific requirements. Please note: TLP runs on every laptop brand. The above packages may be installed via package management tools Ubuntu Software, Synaptic, Depending on your model and kernel version external kernel module s are required to provide battery charge thresholds and recalibration.

The output of tlp-stat -b TLP 1. TLP packages for the newest version are available via Debian Backports read more. You should also mask the following services to avoid conflicts and assure proper operation of TLP's radio device switching options:. The necessary packages are not available from the official Fedora repositories. The installation with layman is described here.

Note: refer to "Which kernel module? The full reference can be read at TLP Configuration.

TLP will start automatically. To avoid having to restart the system, the first time you can start it manually by using the following command:. Please note: there is no TLP background process or daemon that shows up in ps. Hint: all commands described in this section that are shown with sudo, may be executed without sudo in a root shell. Changes to the power source will be ignored until the next reboot or tlp start is issued to resume automatic mode.

Sets the thresholds to the given values. Without parameters the configured settings for the main battery BAT0 are applied. Upon reboot, thresholds are reset to the configured settings.

Applies factory settings i. Note: after setting he thresholds the command terminates; it does not wait for the charge to complete. Sets the lower threshold to upper threshold - 4 to initiate the charge.Daemons typically run independent of users, waiting for events to occur and providing services in response.

Some common daemons include: sshd - listens for and manages incoming? To change the system immediately, use the --now option. For instance: systemctl --now disable ssh will prevent starting sshd at the next boot and stop the daemon immediately. Daemon management with sysvinit Before DebianJessieSystem V -style init scripts were used for daemon management by default.

This allows daemons to operate conditionally, based on the current RunLevel of the computer. For example, a daemon can be configured to run only when the computer is in single-user mode runlevel 1 or, more commonly, when in multi-user mode runlevels For more information, see Init and RunLevel. The Debian Policy Manual sections 9. Daemon init scripts are treated as configuration files by dpkg.

This means they remain on the system after a package is uninstalled, unless the ' purge ' option is used. Common daemon controls Most daemon scripts accept a common set of options, which can be passed directly to the script at the command line, for example: service ssh restart Restarting OpenBSD Secure Shell server: sshd. A brief description of the most common options follows: start : start a service stop : stop a service restart : restart a service without reloading its job config file reload : send a SIGHUP signal to running process status : return the status of a service Starting and stopping daemons in this manner is temporary and will not survive a reboot.

GUI utilities for daemon management Several GUI tools exist to make daemon management even simpler; some popular examples available for Debian include: rcconf and sysv-rc-conf. See also Init RunLevel manpages: inittabinitrcSupdate-rc. Wiki Login.

You signed in with another tab or window.Package management is very important in Linux, and knowing how to use multiple package managers can proof life saving for a power user, since downloading or installing software from repositories, plus updating, handling dependencies and uninstalling software is very vital and a critical section in Linux system Administration.

Therefore to become a Linux power user, it is significant to understand how the major Linux distributions actually handle packages and in this article, we shall take a look at some of the best package managers you can find in Linux. Here, our main focus is on relevant information about some of the best package managers, but not how to use them, that is left to you to discover more.

But I will provide meaningful links that point out usage guides and many more. Dpkg is a base package management system for the Debian Linux family, it is used to install, remove, store and provide information about. It is a very popular, free, powerful and more so, useful command line package management system that is a front end for dpkg package management system. Users of Debian or its derivatives such as Ubuntu and Linux Mint should be familiar with this package management tool. This is also a popular command line front-end package management tool for Debian Linux family, it works similar to APT and there have been a lot of comparisons between the two, but above all, testing out both can make you understand which one actually works better.

It was initially built for Debian and its derivatives but now its functionality stretches to RHEL family as well. You can refer to this guide for more understanding of APT and Aptitude:. It implements the same features as apt-get command line tool. This is the Linux Standard Base packing format and a base package management system created by RedHat. Being the underlying system, there several front-end package management tools that you can use with it and but we shall only look at the best and that is:.

It is an open source and popular command line package manager that works as a interface for users to RPM. You can get a clear understanding of YUM with examples from this how to guide:.

If you have been using Fedora 22 onwards, you must have realized that it is the default package manager. Here are some links that will provide you more information about DNF and how to use it:. It is a popular and powerful yet simple package manager for Arch Linux and some little known Linux distributions, it provides some of the fundamental functionalities that other common package managers provide including installing, automatic dependency resolution, upgrading, uninstalling and also downgrading software.

But most effectively, it is built to be simple for easy package management by Arch users. You can read this Pacman overview which explains into details some of its functions mentioned above. It is a command line package manager on OpenSUSE Linux and makes use of the libzypp library, its common functionalities include repository access, package installation, resolution of dependencies issues and many more.

Importantly, it can also handle repository extensions such as patterns, patches, and products. The main aim of the Portage project is to make a simple and trouble free package management system to include functionalities such as backwards compatibility, automation plus many more.

For better understanding, try reading Portage project page. As I already hinted at the beginning, the main purpose of this guide was to provide Linux users a list of the best package managers but knowing how to use them can be done by following the necessary links provided and trying to test them out.

Users of the different Linux distributions will have to learn more on their own to better understand the different package managers mentioned above.

How does sleep work on a Linux Debian box? I do not usually use the box with a keyboard and mouse. I usually SSH into it. Does it sleep, but then "wake up" when I connect to it?

What if I were running a web server? Would it sleep until a GET request arrived, then wake up, or would it just ignore incoming packets when sleeping? I have a background process that I do not want suspended. How can I check from the command line what the sleep settings are?

How does the "power management" capability decide when to sleep and when not to sleep? Does it look at the running processes and somehow decide to sleep based on what those processes are? That's a large topic. It has been provided with Linux since the early s.

Very briefly, it's managed via the BIOS, which can be configured to check for activity on the devices attached to the computer, and use that to trigger the CPU wakeup. It's possible to wakeup on network activity although the typical Debian system probably is not configured for this.

For that related topic see. As Thomas Dickey said, power management is a quite multi-layered thing. On top of that is usually upowerwhich is the modern interface between user sessions and the power management framework. It communicates over D-Bus. The pm-utils package can use a lot of tools from various packages, like hibernateuswsuspethtoolhdparm and cpufrequtils among others to perform its actions.

Typically a web server would not sleep in the power management sense when waiting for clients: it sure would idle with the CPU underclocked while there is nothing to do, though. Waking up from sleep mode takes a bit of time, and that might cause too much of extra latency in the web service.

My machine is a desktop, but I'd like it to go to sleep after 3 - 4 hours of idling. The default has maximum of 1 hour. It would be nice if there is also an option for running the disks down after a few hours of idling. Then I may not need to put the whole machine into sleep. I'm not saving energy, but my hard disk and my guests' nerves they have to sleep in the same room with the machine.

I'm not saving energy Most don't have computer access, reuse or pay forward an old computer. Obviously you are making no attempt at saving energy, why even bother with a power manager. What happens if you need the system again at 4 hours and 1 minute?

You are the ultimate power-manager of your household, not some little system daemon. On most systems, suspend and hibernate work well and hardly take any time to revive.

If this is a home server, then you could also investigate a Wake-on-LAN type setup. Instead I found out that Gnome is heading to the same way as Unity. There are plenty of other features that have been removed making Gnome quite unsuitable for system with "server characteristics".
