Question about Teamviewer. Irt needs to activate the daemon. But i need Teamviewer only once a month.
services.teamviewer.enable
On Debian i could enable and disable a daemon by hand only when i need it. What about Nixos?
The option you show is doing a few things (you can check here):
- it installs teamviewer
- it creates a systemd service
teamviewerd
In particular, you can usesystemctl status teamviewerd.serviceto check the status of the daemon, orsudo systemctl {start/stop} teamviewerdto start/stop it as usual:
╰─❯ systemctl status teamviewerd.service ─╯

You can also just set services.teamviewer.enable = false; when you don’t need teamviewer, and services.teamviewer.enable = true; when you need it, especially if you use teamviewer very rarely it makes sense.
But that needs a reboot then.? Or when it is set to false, i can enable it only for that session with?
You mean for services.teamviewer.enable = true; ? No, you should not need any reboot: when you set services.teamviewer.enable = true; NixOs is clever enough to start/stop/restart the good services. If you set services.teamviewer.enable = false;, it will completely uninstall teamviewer, so sudo systemctl start teamviewerd.service will not work. You can however disable the daemon if you don’t want it to start by default, I guess:
systemd.services.teamviewerd.wantedBy = lib.mkForce [ ];
should work based on this answer Disable a systemd service while having it in NixOS's conf - #3 by jtojnar

OK, just a moment, i will try it out
OK, without reboot it won’t work. Can later try after reboot…

used this line…
You put both:
services.teamviewer.enable = true;
systemd.services.teamviewerd.wantedBy = lib.mkForce [ ];
?
No, the last line.
And a reboot doen’t help
Oh, you need both: the first line just tells “please install teamviewer and create a new service called teamviewerd”, the second line just says “in the teamviewerd service, remove the line wantedBy, i.e. do not start it automatically”.

Programstarter does not work.
But i can start it via terminal…
On other distro there is a ./application dir filled with .dektop files. The rustdesk application has no starter, but can also started via terminal…
Oh, it is a bug of the derivation, here
The ${placeholder "out"}/bin should be removed to keep the path relative, as advised here What is the recommended use of makeDesktopItem? How to setup the icon correctly? - #6 by zarel as it allows better theming, wrappers by users etc. Right now, the issue is that makeDesktopItem will create first a different derivation, as seen in your screenshot, that contains wnly the desktop file, so the placeholder will point to this nearly empty directory.
I don’t have a computer with me right now, but it can be a nice simple first pull request for you if you want to get involved in nixpkgs. If not, just create a new issue in github with the maintainers of the package (cf names at the end of the above link) and me in mention, explaining what I just explained above.
And right now, you can temporarily fix your issue by using overrideAttrs, like replace anydesk.in your configuration with something like
(anydesk.overrideAttrs (finalAttrs: previousAttrs: {
desktopItems = [
(makeDesktopItem {
name = "AnyDesk";
exec = "anydesk %u";
icon = "anydesk";
desktopName = "AnyDesk";
genericName = description;
categories = [ "Network" ];
startupNotify = false;
})
];
});
)
(I can’t test but should work)
Hi, tomorrow i can look at it. Today i’m on tour for radio production. 1st time live transmitting with nixos. ~10000 listener via FM transmitter…
Oh good luck, seems very impressive. What kind of software/hardware are you using?
Oh, that’s very simple. Some 48V powered condenser microphones, a mixer with usb audio interface and the software “butt” to stream the audio to an icecast server, the studio is playing out the stream to put it on the air.
Yes, now i have a case by not running software…
[wolf@schwoon-desktop:~/APP]$ ./MQTT-Explorer-0.4.0-beta1.AppImage
Could not start dynamically linked executable: ./MQTT-Explorer-0.4.0-beta1.AppImage
NixOS cannot run dynamically linked executables intended for generic
linux environments out of the box. For more information, see:
Frequently Asked Questions — nix.dev documentation
First i search for it in the nix packages…
For App images, you can sometimes use appimage-run ./yourimage.AppImage, but sometimes it fails without obvious error message if a lib is missing. Enabling:
programs.nix-ld.enable = true;
will save you quite some headacke, especially if you develop/use nodejs applications that love to include pre-build binaries. Of course, you can also package the application yourself and submit it in nixpkgs, either from source (for Electron app it might be less obvious than for usual apps), or directly by wrapping the app image, apparently someone already tried to do that here for your program mqtt-explorer.nix · GitHub.
OK, before i’m trying this i check the package “mqttui”. And i found the real-vnc-viewer, that i sometimes use for local vnc server.
But the possibility to run AppImage application is maybe useful and good to know the workaround.
Show with mqttui
