Disabling services

viyoriya

mcxds stop the service and disable the service and check ..

mcxds

viyoriya That gave me the same result as described in my first post.

mcxds thats strange how about a quick restart 😀

mcxds

viyoriya What do you mean? I rebooted the system after executing sudo systemctl stop bluetooth.service and sudo systemctl disable bluetooth.service.

viyoriya

mcxds I meant a restart ... check the /usr/lib/systemd/system/ you will find the files.

check the dependencies systemctl list-dependencies bluetooth.target

mcxds

Also, I have noticed the following: if I manually enable the bluetooth service in my Solus Installation two symlinks are created in /etc/systemd/system, namely /etc/systemd/system/dbus-org-bluez.service and /etc/systemd/system/bluetooth.target.wants/bluetooth.service. And if I disable the bluetooth service afterwards, those symlinks get deleted. What I find interesting is that those symlinks don't seem to exist by default in Solus. They were not there after I installed Solus, although the bluetooth service was running. This is different e. g. in Manjaro where those symlinks exist by default and get removed if you issue sudo systemctl disable bluetooth.service. And that leads to the service not getting started after you reboot the system.

mcxds you can uncheck Blueman in the Startup Applications Preferences

mcxds

kyrios Do you mean this?
I have excluded the Blueman Applet from the startup applications immediately after the Installation of the system. So that cannot be the cause of the bluetooth service getting loaded/started even after having disabled it.

kyrios Can you tell me where i can find this app? I've installed gnome solus but i can't find this app anywhere

Try this:

Create a folder /etc/bluetooth/
copy /usr/share/defaults/bluetooth/main.conf in the above folder
edit /etc/bluetooth/main.conf and look for AutoEnable=true
replace AutoEnable=true by AutoEnable=false then save the file

mcxds

kyrios I created the folder, copied the file, set AutoEnable=false, issued sudo systemctl stop bluetooth.service and sudo systemctl disable bluetooth.service. Then I rebooted the system. The result was:

● bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib64/systemd/system/bluetooth.service; disabled; vendor preset: enabled)
     Active: active (running) since Sat 2020-06-20 08:28:08 CEST; 1min 45s ago
       Docs: man:bluetoothd(8)
   Main PID: 1449 (bluetoothd)
     Status: "Running"
      Tasks: 1 (limit: 9367)
     Memory: 2.0M
     CGroup: /system.slice/bluetooth.service
             └─1449 /usr/lib64/bluez/bluetooth/bluetoothd

So that also didn't prevent the bluetooth service from getting loaded on startup.
I also want to make clear that the bluetooth service is only one example. As I said in my first post I also want to disable certain other services (like cups and modemmanager) that I don't need on a daily basis. I only want to start them when I actually need them. But every one of the services that are enabled by default still gets loaded on startup after disabling it.

Perhaps you can try to mask the service after stopping/disabling it ?
There should be an easier way... but...

Alternately, you should be able to do this with tlp but again that's probably not the answer you are expecting

mcxds

kyrios I know about the maskcommand. But in contrast to the disable command masking a service makes it impossible to start the service even as a dependency which can be dangerous as the Arch wiki points out: https://wiki.archlinux.org/index.php/Systemd#Using_units. So I'm a bit hesitant to use that command for what I want to achieve. Because I only do want certain services to not be started by default on startup, I do not really want to make it impossible to start them whatsoever.

No, unfortunately it's not as it doesn't prevent the bluetooth service from getting loaded on startup.
