Can't activate tlp service on Ubuntu 22.04 #647

[x] I've read and accepted the Bug Reporting Howto [x] I've provided all required tlp-stat outputs via Gist (see below)

Describe the bug

I am using Ubuntu 22.04 on a HP ProBook 6440b. Because the power management was worse on any Ubuntu upgrade in the past I decided to remove power-profiles-deamon and give a try for tlp.

tlp-stat -s --- TLP 1.5.0 --------------------------------------------

+++ System Info System = Hewlett-Packard HP ProBook 6440b BIOS = 68CDD Ver. F.50 OS Release = Ubuntu 22.04.1 LTS Kernel = 5.15.0-46-generic #49-Ubuntu SMP Thu Aug 4 18:03:25 UTC 2022 x86_64 /proc/cmdline = BOOT_IMAGE=/boot/vmlinuz-5.15.0-46-generic root=UUID=c3b22675-9278-4af1-a9dd-5245beab30e9 ro quiet splash vt.handoff=7 Init system = systemd v249 (249.11-0ubuntu3.4) Boot mode = BIOS (CSM, Legacy)

+++ TLP Status State = enabled RDW state = enabled Last run = 17:30:04, 2 sec(s) ago Mode = battery Power source = battery

Error: tlp.service is not enabled, power saving will not apply on boot.

Invoke 'systemctl enable tlp.service' to correct this!

So its clear that service is not started:

sudo systemctl enable tlp.service Synchronizing state of tlp.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable tlp Failed to enable unit: Unit file /etc/systemd/system/tlp.service is masked.

$ ls -l /etc/systemd/system/tlp.service lrwxrwxrwx 1 root root 9 Dez 14 2021 /etc/systemd/system/tlp.service -> /dev/null

This looks worrying for me!

All forum entries said that tlp and power-profile daemons are incompatible. But I removed the last one as I said before.

Can I use tlp for HP ProBook? How can I start the service?

Try to unmask first

sudo systemctl unmask tlp.service
sudo systemctl enable tlp.service

From where did you install the tlp package: from the official Ubuntu repositories or from my PPA? Please show

dpkg -l | grep tlp

Thanks for the quick response! Yes - the unmask seems to solve the problem. Enabling the service has worked for me then, I used the Ubuntu repository: dpkg -l | grep tlp ii tlp 1.5.0-1ubuntu3 all Optimize laptop battery life ii tlp-rdw 1.5.0-1ubuntu3 all Radio device wizard

Is it OK to use the Ubuntu package?

Hopeful tlp solved my problem with the worse shut-down in battery operation and the wrong percentage notification after ac plugin. Have to study tlp documentation. Thanks again.
