Installation

Ubuntu, Debian (PPA)

sudo add-apt-repository ppa:hbriese/fancon; sudo apt-get update
sudo apt install fancon

.deb (alternative)

wget https://github.com/hbriese/fancon/releases/latest/download/fancon_amd64.deb
sudo dpkg -i ./fancon*.deb; sudo apt install -f

Fedora, Red Hat, CentOS (.rpm)

wget https://github.com/hbriese/fancon/releases/latest/download/fancon.x86_64.rpm
sudo yum –nogpgcheck install ./fancon*.rpm

Configuration

/etc/fancon.conf is automatically created on first run once the tests complete

Only 'sensor' & 'temp_to_rpm' for each fan is required to be manually configured

config {
update_interval:
  1000 #Milliseconds between updating fan speeds dynamic
      : true #Interpolate speeds between temps e.g(30 : 800, 50 : 1200)
            results in 1000
        @40 smoothing_intervals : 3 #Intervals over which to smooth RPM changes
            top_stickiness_intervals : 2 #Intervals to wait before decreasing
                RPM temp_averaging_intervals : 3 #Intervals to average
                    temperatures over -

Undetected fans

First try detecting devices using lm-sensors

sudo sensors-detect

• You may need to reboot if unloaded kernel modules were added

Check to see if your device is detected

sensors

Mis-configured or unsupported devices

Devices (fans & sensors) that:

• Expose a sysfs like interface but are not found by lm-sensors
• Are reported as not having the required features but they do

May be configurable by altering their configuration

$XAUTHORITY and or $DISPLAY env variable(s) not set

X11 access is required for NVIDIA control

You will need to configure the unset environmental variable.

Manually configure the unset environmental variable(s)

Inside /etc/profile

• export XAUTHORITY=...; You can find the XAuthority file by running xauth info
• xhost si:localuser:root; May be necessary on Wayland

fancon's Issues

fancon service segfaults

Describe the bug

Since the instructions for Arch installation did not succeed (it seems that Boost 1.72 is too old for this project), I used Boost 1.74 and 1.73 to test. I ran the fancon service command in one terminal, and in the other fancon, and said y to test the fans. The fancon service then segfaults. Also copied is the output from Valgrind.

fancon service output:

Steps to Reproduce

Run sudo fancon service in one terminal, and fancon in the other.

Expected behavior

It should let me configure and test fans, I guess.

Environment

• Version: Latest Git
• OS: Manjaro
• Kernel: 5.9.1

unable to set log levels

How does the logging configuration work?

$ sudo ./fancon --help
fancon argument=value ...
…
-l  log-lvl      Sets the logging level: info, debug, trace, warning, error (default: info)

Based on the help text I assumed one of the following invocations should work. As you can see fancon always reports <debug> No config found

$ sudo ./fancon start -v -l=debug
20/07/07 08:49 [20757] <debug> No config found

$ sudo ./fancon start -v -l debug
20/07/07 08:50 [20844] <warning> Unknown argument 'debug' from statement 'debug'
20/07/07 08:50 [20844] <debug> No config found
Starting controller

Failed build due protoc version

Describe the bug

I tried to wwrite PKGBUILD for the Arch Linux distribution. But I faced with some problems.
Seems current version of the protobuf library not compatible with fancon sources.

Please add how to use the program in the readme

Hi

Its would be really great if instructions on how to use the program were included in the readme. I understand that it is somehow controlled through the command line but other than that I can't work it out.

A GUI would be really amazing, currently there don't seem to be any other options for Ubuntu

Thaniks very much for making this

please release a new version

Seems like release 0.20.1 does not compile (#8) and these issues were fixed since then. How about releasing a new version so users don't have to resort to git versions? (Ideally after fixing #12 ;-)

Not doing it on a macBook Pro

Hi,

It's not working on Mac, there's some msg fancon test gives that it can't find files in /sys/class/..., messy output about pwm or similar, what doesn't surprise when you're aware that all seems to be is in /sys/devices/platform/applesmc.768/ where you can change fans via rpm. Can this be fixed? Listing fans and sensors seems ok, it's applesmc/1:fan1, applesmc/1:fan2 for fans or alike..

fancon always tests fans, tries to write /etc/fancon.conf

I compiled git version de5bb40 on Fedora 31.

Steps to Reproduce

sudo ./fancon start
20/07/06 16:45 [81198] <warning> Unknown argument 'start' from statement 'start'
Starting controller
Testing fans, this may take a long time.
Don't stress your system!
Tests …

Expected behavior

• no warning about "Unknown argument 'start'"
• fancon just uses the preconfigured /etc/fanconf.conf, does not write to /etc

Environment

• Version: git version de5bb40
• OS: Fedora 31

unable to compile git since commit d76e6780

Describe the bug

I'm unable to compile fancon since git commit d76e678 (I used cmake … -DNVIDIA_SUPPORT=OFF ..).

commit d76e6780ff87fdb4a76e65934b0592d6b338ef6d
Author: Hayden Briese <[email protected]>
Date:   Thu May 7 02:02:38 2020 +1000

    - Fixed bug where configured NVIDIA devices may be run without NVIDIA control
    
    Signed-off-by: Hayden Briese <[email protected]>

Steps to Reproduce

$ make

Expected behavior

compilation works

Environment

• Version: fancon git (commit d76e678)
• OS: Fedora 31
• Kernel: 5.7.7
• clang: 9.0.1
• g++: 9.3.1

Additional context

fancon_amd64.deb for 0.23.7: "not installable" dependencies on Bookworm

Describe the bug

The following packages have unmet dependencies:
 fancon : Depends: libgrpc++1 but it is not installable
          Depends: libprotobuf23 (>= 3.12.3) but it is not installable

Steps to Reproduce

After downloading from https://github.com/hbriese/fancon/releases/download/0.23.7/fancon_amd64.deb
apt install /tmp/fancon_amd64.deb

Expected behavior

fancon installed

Environment

• Version: 0.23.7
• OS: Debian Bookworm
• Kernel: 6.1.0-15-amd64

core dump when running test

I'm testing fancon_0.12.0_amd64.deb on Ubuntu 17.04

$ fancon test
07/28 15:34 [12860] <debug> NVIDIA fan control not supported
Adding 1 new fans
Starting tests. This may take some time (to ensure accurate results)
terminate called after throwing an instance of 'std::ios_base::failure[abi:cxx11]'
  what():  basic_filebuf::underflow error reading the file: iostream error
Aborted (core dumped)

the fancon.conf contains following:

# <Fan UID>     <Sensor UID>     <Fan Config>
#nouveau/0:fan1
dell_smm/1:fan1
dell_smm/1:fan2

Start with root/systemd unit fails

Describe the bug

Failed with NVIDIA control by root user.

# LANG=C fancon
No protocol specified
20/05/06 20:27 [109117] <warning> $XAUTHORITY env variable(s) not set, set to enable NVIDIA support
20/05/06 20:27 [109117] <fatal> X11Display must be connected
terminate called after throwing an instance of 'std::exception'
  what():  std::exception

But I can't run as normal user:

$ funcon
20/05/06 20:32 [109236] <fatal> Must be run as root

Seems service which needs running the Xorg should be running by non root user.

Steps to Reproduce

• build fancon with NVIDIA support
• run fancon by root ro with systemd unit file

Expected behavior

Run without errors with systemd unit file.
