[SOLVED] How do I set a program to run as daemon?

rado84 · 2019-05-12 14:48:41

I was using Mint for 2 years and recently I decided to switch to Arch, following the advice of a friend. For the most part I manage either on my own or using a search engine, rarely I resort to help from others. But there's one thing for which I can't find the "how to": how to set a program to run as a daemon? In Mint the Gnome-screenshot was running as a daemon and it was only a matter of hitting the printscreen button in order to make a screenshot. But in Arch I have to start the program manually and click the interface button in order to make a screenshot. So, how do I do the same in Arch?
I tried adding gnome-screenshot to the list of autorun programs but this only shows the program window and I still have to click the button to take a screenshot. On top of that gnome-screenshot's interface is included in the screenshot and I don't want that.

A program is either designed to be ran as a daemon or it is not designed to be ran as a daemon. From what I'm seeing gnome-screenshot is not intended for that. So it's more likely that there were global hotkeys assigned to invoke it in a specific way. Which environment did you use in Mint and which are you using in Arch? If it's Cinnamon in both, go through your shortcut settings.

Running a program "as a daemon" will not change it's behavior. The program you are referring to either does or does not bind the printscreen button - it sounds like it doesn't. Running it as a daemon will not magically give it new behavior that it doesn't already have.

So forget that terminology, it's completely the wrong thing to look for. You want to set a keybinding to run a screenshot command - that's all.

Yes it is.

I've set a screenshot key long before I realized there was no gnome-screenshot installed in the system. Even after installing it, if I press PrntScrn, nothing happens - no screenshot is created.

Then you have not set PrntScrn to be a screenshot key. If you want help with that, we'll need information about that. As-is, this is a clear X-Y question. Running a program as a daemon will not help you in any way: the program will still not bind the key, and it will still display it's interface.

I don't use Cinnamon but the ArchWiki says that simply installing the gnome-screenshot package provides the functionality you want and also that the default key is PrtSc:

https://wiki.archlinux.org/index.php/Ci … Screenshot

Are you sure the PrtSc key isn't bound to some other application?

Try this to show the screenshot key:

gsettings get org.cinnamon.desktop.keybindings screenshot

And this to show any custom keybindings:

gsettings get org.cinnamon.desktop.keybindings custom-list

EDIT: corrected commands (but might still be wrong).

OK, what info do you need?

This will show the screenshot key:
gsettings get org.gnome.settings-daemon.plugins.media-keys screenshot
This will show any custom keybindings:
gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings

[rado@anarchy]: ~>$ gsettings get org.gnome.settings-daemon.plugins.media-keys screenshot
No such schema “org.gnome.settings-daemon.plugins.media-keys”
[rado@anarchy]: ~>$ gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings
No such schema “org.gnome.settings-daemon.plugins.media-keys”
[rado@anarchy]: ~>$

I can't say if it's bound to another app but I doubt it is. No other app uses this key for anything. I mean, it wasn't used by any other app in Mint and since I know Cinnamon better than the other DEs, I'm quite sure no other apps use PrnScrn key.

^ Sorry, I was using the wrong schemas, check my edit or use dconf-editor to browse the settings.

No such key “screenshot”

['custom0']
[rado@anarchy]: ~>$

No such key, it says. Which is weird bc when I open "Settings" --> "Keyboard" --> "Hotkeys", PrntScrn is set for "Screenshot". I set it myself before I downloaded gnome-screenshot.

Edit: I just did a logout (not reboot) in order to see if some other settings will work and suddenly gnome-screenshot started making screenshots. Can it be really? A reboot changes nothing whereas logging out makes things work? That doesn't make any sense to me.

Well I don't use Cinnamon so I'm shooting in the dark here.

Have you tried dconf-editor? Navigate to org.cinnamon.desktop.keybindings and see what options there are.

rado84 · 2019-05-12 17:16:03

I know of dconf-editor, it's one of the first things I install in any distro. There's no "keybindings" option. Anyway, it seems logging out somehow fixed the problem - see my previous post edited. Still, thanks everyone for answering.

For completeness

gsettings get org.cinnamon.desktop.keybindings.media-keys screenshot
['Print']
