Conflict with power-profiles-daemon

power-profiles-daemon (contained in GNOME 40 and newer) might be contained in the default install of your distribution.

Beginning with version 1.4 tlp start and tlp-stat -s will detect the conflict:

Error: conflicting power-profiles-daemon.service is enabled, power saving will not apply on boot.
>>> Invoke 'systemctl mask power-profiles-daemon.service' to correct this!


  1. Uninstall the power-profiles-daemon package (preferred)

  2. Disable power-profiles-daemon with

    sudo systemctl mask power-profiles-daemon.service

and reboot.

The following TLP version 1.5 distribution packages will take care of removing the conflicting power-profiles-daemon package when installed:

  • Arch Linux

  • Debian Bookworm/Sid

Does TLP conflict with other power management tools?

Yes. Using another tool simultaneously means that TLP’s settings get overwritten by the other tools settings (and vice versa), so actual power saving gets unpredictable. Special cases are explained in the following.

power-profiles-daemon: see above.

Powertop: please refer to Powertop.

Slimbook Battery: uses TLP as backend to apply power saving and for this purpose continuously overwrites your TLP configuration. If you want to configure TLP individually, you need to uninstall Slimbook Battery first.

system76-power: works on the same set of kernel settings. Do not use together with TLP.

thermald: thermald’s purpose is to limit power dissipation before the laptop’s temperature gets critical. TLP enables power saving to optimize battery power especially in idle and low workload situations. TLP does not conflict with thermald.

throttled: only throttled’s dynamic HWP_Mode setting interferes with TLP’s actions. If you want to use it, disable the feature in TLP by configuring CPU_ENERGY_PERF_POLICY_ON_AC=””.

Must I enable TLP’s systemd service units?

Symptoms: tlp-stat -s shows

Error: tlp.service is not enabled, power saving will not apply on boot.
>>> Invoke 'systemctl enable tlp.service' to correct this!


Error: tlp-sleep.service is not enabled, power saving will not apply on boot.
>>> Invoke 'systemctl enable tlp-sleep.service' to correct this!

Answer: yes, the service units are indispensable for correct operation:

  • tlp.service: applies power saving settings and charge thresholds as well as switching radio devices on system boot and shutdown

  • tlp-sleep.service: applies powers saving upon system suspend and resume (not applicable for version 1.3 and higher)


Debian, Fedora and Ubuntu enable the service by default as part of the package Installation, others such as Arch Linux don’t. If unsure check the output of tlp-stat -s for corresponding notes.

Does TLP run on my laptop (not a ThinkPad)?

TLP runs on every laptop brand. A few features are available on IBM/Lenovo ThinkPads only.

Does TLP make sense on newer laptops / with newer Linux versions?

Yes, of course.

The Linux kernel has accumulated many power saving features over the years, but not all are enabled by default. It seems to be really hard for the kernel developers to fully debug power saving on all possible hardware, so power saving stays disabled for many drivers and it’s up to the user to enable it.

Conclusion: a userspace tool like TLP is still needed to enable power saving globally.

Should I install TLP inside a virtual machine?

No. It is not effective to run a power management tool inside a virtual machine guest. Install TLP in the host operating system instead.

Ubuntu/Debian: I do not use Network Manager, how do I install tlp without tlp-rdw?

sudo apt install --no-install-recommends tlp

Ubuntu: How do I prevent the installation of postfix as a dependency?

The package tlp recommends smartmontools which pulls postfix (via recommends too). Use:

sudo apt install --no-install-recommends tlp tlp-rdw ethtool smartmontools

My Linux distribution does not provide a TLP package, how do I install it?

See Other Linux Distributions.

How do I install TLP on a development release of my distribution?

TLP packages for new distribution versions appear in due time for the release. If you want to use TLP with alpha or beta releases, download the packages for the predecessor and install them manually with your favorite package manager.
