Issue description

during my last update, which was probably between revision 1445 and 1449 a nixos-rebuild switch restarted my X-server which was quite a surprise.

  services.xserver = {
    enable = true;
    videoDrivers = [ "intel" ];
    deviceSection = ''
      Option      "AccelMethod"  "uxa"
    '';
    layout = "us";
    xkbOptions = "eurosign:e";
    config = ''
      Section "InputClass"
        Identifier "Logitech"
        MatchProduct "Logitech USB Laser Mouse"
        MatchIsPointer "true"
        MatchDevicePath "/dev/input/event*"
        # maps MMB to a different button
        Option "ButtonMapping" "1 8 3 4 5 6 7 2"
      EndSection
      Section "InputClass"
        Identifier "TPPS/2 IBM TrackPoint"
        MatchProduct "TPPS/2 IBM TrackPoint"
        MatchDevicePath "/dev/input/event*"
        Option "EmulateWheel" "true"
        Option "EmulateWheelButton" "2"
        Option "Evdev Wheel Emulation Timeout" "200"
      EndSection
    '';
    windowManager.i3.enable = true;
    displayManager = {
      sessionCommands = with pkgs; ''
        # synchronize clipboards
        ${autocutsel}/bin/autocutsel -s PRIMARY &
      '';
    };
  };

i'm not sure where to start but it could either be a systemd dependency which restarted xorg or it could be xorg itself.

  • nixos/modules/services/x11/xserver.nix (looks good)
  • nixos/modules/services/x11/window-managers/i3.nix (looks good)
  • display-manager (?)

just added some bogus into:

    displayManager = {
      sessionCommands = with pkgs; ''
        # synchronize clipboards
        # bogus added
        ${autocutsel}/bin/autocutsel -s PRIMARY &
      '';
    };

Not sure if it 's for the same reasons or/and because I mixed home-manager i3 config + system's awesome but that did occur to me several times. The way nixos kicks us out of X is kinda violent IMO. I don't know if it can be warned upon/deferred/disallowed with a flag but that could prove helpful.

I think #37739 is a bit different (17.09 -> 18.03, IIRC I was fine on nixos-unstable at the time of that issue) but both seem to be related to systemd.

But #39791 could be identical. The same thing happend to me recently on nixos-unstable and is reproducible. Unfortunately I didn't had time to have a closer look yet. In my case I suspect that it was due to restarting systemd-logind (After=systemd-logind.service) or systemd (systemctl daemon-reexec).

Restart=always is fine ("Configures whether the service shall be restarted when the service process exits, is killed, or a timeout is reached", see man systemd.service).

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.

Hi @qknight,

With the changes over the past 6 years, including some I know about, I suspect this particular shouldn't be an issue anymore.

If you can still reproduce this issue, please feel free to re-open this issue.

(@primeos: same goes to you, if you can reproduce the issue again, feel free to add details and re-open.)

To anyone else: if you think you are experiencing a similar issue, please open a new issue. Feel free to cross-reference this issue. It is more likely that you are observing the same symptoms, but are having different issues.
