About

TuxClocker is a hardware controlling and monitoring program. TuxClocker consists of a DBus daemon and a Qt GUI that uses the daemon.

Features

• Supports any number of devices at once
• Read and write device properties (Click on a selected node to edit)
• Edit multiple similar nodes at once by selecting them and starting editing
• Connect any writable property to any readable property, for more possibilities than just fan curves. Currently only possible with range-based writable properties (Right click on a node)
• Reset writable properties to default (Right click on a node)
• Profiles
• Option to apply profile settings on startup/profile change

Currently missing from earlier releases

These are missing from the 1.3.0 release, but present in the 0.1.1 release.
Refer to the 0.1.1 release readme if you wish to use these.

Currently supported devices and features

Nvidia GPUs

600 -series and above

• Support for multiple fans on one GPU
• Fan mode
• Fan speed
• Core and memory clocks (Xorg works, also experimental support elsewhere)
• Power limit
• Temperatures
• Utilizations
• VRAM usage monitoring

600 to 900 -series

AMD GPUs

NOTE ABOUT AMD GPUS:

When writing to pp_od_clk_voltage (writable properties in the ‘Performance’ subtree), power_dpm_force_performance_level is implicitly set to ‘Manual’. Normally this shouldn’t matter, but if you set ‘Performance Parameter Control’ to anything other than ‘Automatic’ or ‘Manual’ you may get unexpected results due to the value being overridden by other settings. You can work around this by removing the setting values from your profile by right clicking on the properties.

• Temperatures
• Fan mode
• Fan speed

CPUs

Some CPU features require kernel module msr to be loaded.

• Frequency monitoring
• Utilization monitoring

• CPU Governor minimum/maximum frequency setting

AMD and Intel CPUs

• Energy-Power Preference setting (called ‘Power Usage Mode’ in the program)
• Power usage monitoring (MSR)

Intel CPUs

• Temperature monitoring (coretemp)
• Energy-Performance Bias setting (called Power Saving Tendency in the program)
• Core and memory power usage monitoring (MSR)
• Voltage monitoring (MSR)

Possible future improvements

• Support for more devices
• Support for more platforms than Linux
• Easier to discover UI
• CLI interface

Installation

Prerequisites

NVIDIA GPUs require Coolbits set to enable editing of most writable properties (31 for all functionality)

AMD GPUs require the amdgpu.ppfeaturemask boot parameter to edit writable properties (amdgpu.ppfeaturemask=0xffffffff for all functionality)

Using prebuilt binaries

You can use the tuxclocker.tar from the release page if you don’t want to compile. The tarball is generated from the mkTarball.sh script.

• Download the tarball into some empty directory
• Extract the contents eg. (tar xf tuxlocker.tar)
• For NVIDIA users, run ./nvidiaInstall.sh before running to get suitable NVIDIA libraries through Flatpak
• Run sudo echo && ./run.sh in the same folder (sudo is needed for the daemon)

Using distribution packages

This list may contain unofficial distribution packages, maintained by other people not directly related with this project.

For openSUSE Tumbleweed

NOTE: Due to NVIDIA proprietary driver license problems the package is built without NVIDIA modules. See issue#65 for more info.

Install the tuxclocker package from OBS. Or via terminal:

sudo zypper in opi
opi tuxclocker

Dependencies

Required: qt (charts, base, dbus), boost-system, boost-filesystem, meson

Optional:

• libnvml, libxnvctrl, xlib - NVIDIA support
• libdrm - AMD support
• python-hwdata, libpython3, python3 - Prettier AMD GPU names

NOTE: some distros like NixOS only contain libnvml as part of a fully featured CUDA package.

Note that these packages are likely called something different on each distribution.

For Nix

nix-shell release.nix

For Ubuntu

NOTE: Some Ubuntu releases provide libboost which is too old (1.76 or newer is required)

python-hwdata is not packaged for Ubuntu but can be acquired on OBS.

Compiling

Meson options

--prefix=<path> (install location prefix, usually '/usr')
-Dplugins=<true/false>
-Ddaemon=<true/false> (builds and installs 'tuxclockerd' binary/daemon)
# The following options allow you to abort the build if some components can't be built
-Drequire-nvidia=<true/false>
-Drequire-amd=<true/false>
-Drequire-python-hwdata=<true/false>

Clone, build and install

git clone https://github.com/Lurkki14/tuxclocker
cd tuxclocker
git submodule init
git submodule update
meson build <meson options>
cd build
ninja && sudo ninja install

Running

Once you have installed everything into a proper location, TuxClocker is available through a launcher or with tuxclocker-qt from the terminal.

If TuxClocker shows up with no items, there may be a problem with connecting to the DBus daemon. Refer to your system documentation on where DBus system service entries should be located. Alternatively, you can launch the needed components manually as explained in the Developing/Scripts section of the README.

Tests

NOTE: building tests requires passing -Dtest=true to meson.

Tests are located in src/test. Run them with meson test.

Formatting

TuxClocker uses clang-format. Code should be formatted with the provided clangFormat.sh script.

NOTE: to get designated initializers formatted like so:

auto Foo = Foo{
    .bar = 1,
    .baz = 2,
};

a trailing comma should be used after the last member (clang-format weirdness).

Scripts

There are a few scripts in dev/ for development convenience, mainly to deal with DBus. A separate DBus instance and custom config file is used, so the TuxClocker daemon is able to be registered without installing service files into the system.

Note: the following scripts assume TuxClocker is installed to inst/ and libraries to inst/lib so meson should be called as follows:

meson build --prefix=$(pwd)/inst -Dlibdir=lib

The scripts should be used in this order (they all have to be running simultaneously, so probably best to run in separate terminals):

dev/tuxclockerd-start.sh Starts a separate DBus instance with dbus-run-session and launches tuxclockerd using the separate DBus instance and LD_LIBRARY_PATH set to find the built libtuxclocker.

dev/gui-start.sh Launches the TuxClocker GUI making it connect to our separate DBus instance, so it can find the TuxClocker DBus service.

You can also use a program like d-feet if you are only making changes to the daemon. (To be documented)
