How to run from boot on Ubuntu 16.04

[cdysthe]

Hi,

I am not a developer so please bear with me. I have followed the installation instructions and I can run yoga_fan with "sudo ./yoga_fan. I then ran this:

sudo -s
make install
update-rc.d yoga_fan_daemon defaults

The install went well with this output:

-- Up-to-date: /usr/local/usr/bin/yoga_fan
-- Up-to-date: /usr/local/etc/init.d/yoga_fan_daemon

I get this error message:

update-rc.d: error: initscript does not exist: /etc/init.d/yoga_fan_daemon

I also enabled the service with systemd and the symlink was created. When I reboot I can not see a yoga_fan process. What am I missing?

had the same problem, inside the lenovo_yoga_fan_control, run the comman cp yoga_fan_daemon ../../../etc/init.d

then try running the update command again

Hello, @Cono52 and @cdysthe.
Seems it's a bug with cmake install path. I faced it once, when make install command put binary file and init.d script in the /usr/local/ prefix instead of /, i.e. just root prefix.
Anyway, I can recommend you only make project and manually copy all files to the locations:

cd lenovo-yoga-fan-control
cmake CMakeLists.txt
make
# sudo ./yoga_fan # just check whether it's working or not :)
# do not run make install
sudo cp yoga_fan /usr/bin/yoga_fan
sudo cp yoga_fan_daemon /etc/init.d/yoga_fan_daemon
sudo chmod 755 /usr/bin/yoga_fan /etc/init.d/yoga_fan_daemon
sudo update-rc.d yoga_fan_daemon defaults
# sudo /etc/init.d/yoga_fan_daemon restart # check init script

I believe it will work.

P.S. A thousand apologies for so late answer 😔.

Quick question. If i run it with systemd do i need to worry about this at all? Thank you for getting back to us on this! :-)

@cdysthe
If you use system.d you should copy the service file yoga_fan.service to the /etc/systemd/system/ directory. After that enable service by sudo systemctl enable yoga_fan.service. That's all if I'm not mistaken. So you can chose init.d script or system.d.
