[Nix-dev] Teamviewer will not connect to remote machine

[Christoph-Simon Senjak]

Hi.

I am trying to use the TeamViewer client on NixOS. I added `teamviewer` 
to my `environment.systemPackages` in `configuration.nix`, and set

  services.teamviewer.enable = true;

Mostly, after boot, the client complains about no network connection 
being available, but after restarting teamviewerd, I can log in to my 
account. However, after when I select my remote machine, and try to 
connect to it, the teamviewer main window minimizes, but no remote 
connection window shows, as it would do normally.

My first guess is that, since everything is in wine, there is some 
problem with spawning another windows process. However, I have now idea 
how to confirm that. It works inside my Win10 VM and it works inside my 
Debian VM, so it cannot be a problem with my account or remote machine.

I would appreciate any help. I don't even know how to further 
investigate on this problem. Journalctl does not say anything, and the 
stdout of teamviewer also has no info. The gui.log sais, when trying to 
connect,

fixme:nls:GetGeoInfoW -1 4 0x1dee2ec 3 0
fixme:nls:GetGeoInfoW -1 4 0x1dee2ec 3 0
fixme:nls:GetGeoInfoW -1 4 0x1dee2ec 3 0
fixme:nls:GetGeoInfoW -1 4 0x1dee2ec 3 0
fixme:nls:GetGeoInfoW -1 8 (nil) 0 0

The file TeamViewer12_Logfile.log contains lots of entries like

2017/03/17 16:41:35.393     8     9 GX0!  TeamViewer.exe: unable to send 
command 7
2017/03/17 16:41:36.393     8     9 GX0!  TeamViewer.exe: unable to send
