[SOLVED] Running a script as root at startup/login

Basically, the only way i can enable turbo boost, as found on the  appears to be, weirdly, via 

sudo x86_energy_perf_policy --turbo-enable 1

which is pretty annoying since it means that I have to run it every time...
Since that might be useful, I'm running with KDE on an i5-8265, and I had the same problem on manjaro too.
Output of some commands, might be useful, I hope

sudo x86_energy_perf_policy --turbo-enable 1 && cpupower frequency-info

Weird how the "Supported" part also switches from yes to no, together with the "Active"

Re: [SOLVED] Running a script as root at startup/login

Create a oneshot systemd service that runs the command e.g.  /etc/systemd/system/energyPerfPolicy.service 

[Unit]
Description=Apply perf energy policy
ConditionVirtualization=!container

[Service]
Type=oneshot
ExecStart=/usr/bin/x86_energy_perf_policy --turbo-enable 1
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

systemctl enable energyPerfPolicy.service

see https://wiki.archlinux.org/title/System … unit_files as well.

Re: [SOLVED] Running a script as root at startup/login

How about this in /etc/tmpfiles.d/00-turbo.conf:

w /sys/devices/system/cpu/intel_pstate/no_turbo - - - - 0

Apologies if you've already tried writing to that file.

Re: [SOLVED] Running a script as root at startup/login

Thanks for both answers! You two spend a lot of time here, don't you? Not the first time I'm seeing you here
Appreciate it, though.
I will try both suggestons tomorrow and let you know
Also, I'd already tried using systemd, but that didn't work
Maybe I did something wrong, we'll see
