I have a Dell Latitude E6430 laptop. I just installed tlp:
sudo apt install tlp cpufrequtils
This worked successfully. I then entered:
sudo systemctl enable tlp.service
This produced the error message,
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.
I COULD unmask tlp.service; but should I do this? The fact that tlp,service is masked suggests on the architecture of this Dell Latitude, the system power management is better?
I'd appreciate advice on which is best on this architecture.
