Tip Top Tips: Enabling Nvidia Dynamic Boost

Editor’s Note: Tip Top Tips is a semi-monthly column in The PCLinuxOS Magazine. Periodically, we will feature – and possibly even expand upon – one tip from the PCLinuxOS forum. The magazine will not accept independent tip submissions specifically intended for inclusion in the Tip Top Tips column. Rather, if you have a tip, share it in the PCLinuxOS forum’s “Tips & Tricks” section. Occasionally, we may run a “tip” posted elsewhere in the PCLinuxOS forum. Either way, share your tip in the forum, and it just may be selected for publication in The PCLinuxOS Magazine.

Editor’s Note #2: WARNING! Use this tip with extreme caution! You MUST follow directions explicitly as given. There is a big risk of borking your installation if things are not done correctly. This tip is aimed more at experienced users who are comfortable with tinkering with their system at this level. If you have ever borked your system by not explicitly following the directions provided, then this tip is most likely NOT for you! In either case, it might be a good idea to have timeshift running, so that you can roll back to a working version of your system should things not go as anticipated.

This month’s tip is from MBL.

CPU: Ryzen 5 5600H GPU: RTX 3060 NVIDIA Laptop

The FN + Q keyboard shortcut allows you to manage this (blue = silent, white = auto, red = performance).

Note: I disabled the “optimus/prime” option in the BIOS to be in full NVIDIA mode.

By default, my graphics card is locked at 80W. I unlocked the card so that it can now reach 130W max.

Technical background — what Dynamic Boost does
(https://download.nvidia.com/XFree86/Linux-x86_64/535.54.03/README/dynamicboost.html)

According to the official Nvidia documentation:

Dynamic Boost is managed by an nvidia-powerd daemon that relies on systemd and D-Bus to coordinate CPU⇄GPU and increase GPU power when the CPU is not saturated.

Under normal conditions in Linux, without this service, cards like my RTX 3060 Laptop remain locked at the base TGP (~80 W), whereas with Dynamic Boost they can reach up to ~130 W.

Specific limitations in PCLinuxOS

PCLinuxOS does not use systemd, so nvidia-powerd.service does not exist and cannot be enabled. Thus, the standard documentation does not apply as is. The absence of systemd means that standard Nvidia dynamic management cannot be used.

Step 1. Check GPU compatibility

First and foremost, you need to make sure that your laptop supports Dynamic Boost:

1) Check Dynamic Boost support via nvidia-settings:

nvidia-settings -q DynamicBoostSupport

Attribute ‘DynamicBoostSupport’ (82ju:0[gpu:0]): 1.
'DynamicBoostSupport' is a boolean attribute; valid values are: 1 (on/true) and 0 (off/false).
‘DynamicBoostSupport’ is a read-only attribute.
‘DynamicBoostSupport’ can use the following target types: GPU.

1 = compatible

0 = not compatible, meaning it cannot be enabled.

2) Check the GPU power limits:

nvidia-smi -q | grep -E "Current Power Limit|Max Power Limit"
Current Power Limit : 80.00 W
Max Power Limit : 130.00 W
Current Power Limit : N/A
Max Power Limit : N/A

Current/Default Power Limit = 80 W

Max Power Limit: must be higher than current/default setting (e.g., 130 W).

If Max Power Limit = Default, then Dynamic Boost is impossible.

Step 2: Check the Nvidia driver

Drivers >= 550 block nvidia-smi -pl for laptops.

Dynamic Boost only works via nvidia-powerd from this version onwards.

On PCLinuxOS, the official .run package contains the binary, but the distro packages may exclude it.

Step 3: Install the prerequisites

cpufrequtils (optional, useful if you want to manage the CPU):

sudo dnf install cpufrequtils

Check that D-Bus is working:

ps aux | grep dbus-daemon

dbus-daemon --system must be running.

Step 4: Download the official Nvidia driver

1) Download driver 550.163.01 (corresponds to the version I have on PCLinuxOS):

wget https://download.nvidia.com/XFree86/Linux-x86_64/550.163.01/NVIDIA-Linux-x86_64-550.163.01.run

2) Make the downloaded .run executable:

chmod +x NVIDIA-Linux-x86_64-550.163.01.run

Step 5: Extract the contents of the .run file without installing and go to the folder.

sh NVIDIA-Linux-x86_64-550.163.01.run --extract-only

cd NVIDIA-Linux-x86_64-550.163.01

Step 6: Check for the presence of the nvidia-powerd binary

find . -name "nvidia-powerd"
./nvidia-powerd

If found, then this is perfect. If not, then this .run version does not support Dynamic Boost.

Step 7: Check for the presence of the D-Bus file

find . -name "*dbus*.conf"

./nvidia-dbus.conf

Expected file: nvidia-dbus.conf

Step 8: Copy the necessary files to the system

1) Copy the nvidia-powerd binary:

sudo cp ./nvidia-powerd /usr/bin/

sudo chmod +x /usr/bin/nvidia-powerd

2) Copy the D-Bus file:

sudo cp ./nvidia-dbus.conf /usr/share/dbus-1/system.d/

sudo chmod 644 /usr/share/dbus-1/system.d/nvidia-dbus.conf

Step 9: Manually launch nvidia-powerd for testing

sudo /usr/bin/nvidia-powerd --verbose

The logs should show that it is running without errors.

Check the power draw:

watch -n1 nvidia-smi

or launch nvtop if installed

nvtop

Launch a game/benchmark. Your power draw should exceed 80 W.

Step 10: Automate launch at boot (without systemd)

1) Modify /etc/rc.d/rc.local:

sudo nano /etc/rc.d/rc.local

Add to the end:

# Start Nvidia Dynamic Boost daemon
/usr/bin/nvidia-powerd &

2) Make rc.local executable:

sudo chmod +x /etc/rc.d/rc.local

3) Restart the machine.

4) Check after reboot:

ps aux | grep nvidia-powerd
root 3646 0.4 0.0 151828 3048 ? Sl 16:35 1:14 /usr/bin/nvidia-powerd
mbl 5852 0.0 0.0 32748 2196 pts/1 S+ 21:15 0:00 grep --color nvidia-powerd

or with the command nvidia-smi or nvtop.

Key points

systemd is not necessary, rc.local is sufficient to launch the daemon.

Dynamic Boost only works if:

DynamicBoostSupport = 1

Max Power Limit > Default Power Limit

D-Bus is functional and allows nvidia-powerd (.conf file present)

nvidia-smi -pl does not work with 550+ on laptops, this is normal.

There you go, my RTX 3060 card can now go up to a maximum of 130W.

Example FN + Q with red light

nvidia-smi -q | grep -E "Current Power Limit|Max Power Limit"
Current Power Limit : 130.00 W
Max Power Limit : 130.00 W
Current Power Limit : N/A
Max Power Limit : N/A

Or with nvtop:

The power range in AUTO mode: 80-95-115-130W

That's it, feel free to share your feedback on this topic.

I did this with the help of AI. I even have three scripts that it gave me to do it. I haven't tested these scripts yet, but I can post them here for verification and improvement.

Does this also work with the “optimus/prime” mode like under PCLinuxOS? (gpu radeon + gpu nvidia)

I used the same process as the full NVIDIA version.

Yes it does! (130W also here)
