Need help with QML and systemd service creation

ds2k5

Hi,
I try to convert a Project from UB 16.04 to 20.04
but have the issue that a switch "Stop charging after limit reached" is not working.

Could somebody help me ?
I did not understand why.
I belive that the Service may be not installed.

gitlab --> ubtouch2 / fork-indicator-upower

Sorry did not have the right to post a link

indeed, we use now systemd, you can find an example here in
https://gitlab.com/lduboeuf/battery-saver

i can't show you exactly since i'm on UT with Morph bot supporting gitlab anymore but you should find a .service somewhere and the service installation is done with a python script

Hi,
how to find the systemd script for your APP ?

did install the APP but did not find a systemd script

phablet@ubuntu-phablet:~$ systemctl | grep -i batt
phablet@ubuntu-phablet:~$

phablet@ubuntu-phablet:~$ ls -la /opt/click.ubuntu.com/batterysaver.lduboeuf
total 12
drwxr-xr-x  3 clickpkg clickpkg 4096 Oct 28 07:00 .
drwxr-xr-x 41 clickpkg clickpkg 4096 Oct 28 07:00 ..
drwxr-xr-x  7 clickpkg clickpkg 4096 Oct 28 07:00 1.8.0
lrwxrwxrwx  1 clickpkg clickpkg    5 Oct 28 07:00 current -> 1.8.0

$ ls -la /home/phablet/.local/share/batterysaver.lduboeuf/batterysaver
ls: cannot access '/home/phablet/.local/share/batterysaver.lduboeuf/batterysaver': No such file or directory

$ ls -la /home/phablet/.local/share/batterysaver.lduboeuf/
ls: cannot access '/home/phablet/.local/share/batterysaver.lduboeuf/': No such file or directory

Did deinstall the APP an reInstall but the binary is not there

$ ls -la /home/phablet/.local/share/batterysaver.lduboeuf/batterysaver
ls: cannot access '/home/phablet/.local/share/batterysaver.lduboeuf/batterysaver': No such file or directory

@ds2k5 Now that i am on PC, it should be better

So to check the current status of the background user service:
systemctl status --user batterysaver
we can see that/home/phablet/.config/systemd/user/batterysaver.service is used.

So user service has to be copied to /home/phablet/.config/systemd/user/ and started accordingly, this is what is done with that python script:
