Calls to dbus-update-activation-environment

Note that the default sway configuration template /etc/sway/config includes /etc/sway/config.d/*, and specifically includes /etc/sway/config.d/nixos.conf, which has the following contents:

   # Import the most important environment variables into the D-Bus and systemd
   # user environments (e.g. required for screen sharing and Pinentry prompts):
   exec dbus-update-activation-environment --systemd DISPLAY WAYLAND_DISPLAY SWAYSOCK XDG_CURRENT_DESKTOP

Likewise, the example configuration in the wiki creates a script /bin/dbus-sway-environment that attempts to call dbus-update-activation-environment. (In spite of the partial redundancy with /etc/sway/config.d/nixos.conf, the dbus-sway-environment script still seems to be necessary to get the required user dbus services successfully started.) However, neither of these attempts to execute

   dbus-update-activation-environment

works unless dbus-update-activation-environment is in the path (e.g., unless there is a symlink /run/current-system/sw/bin/dbus-update-activation-environment pointing at the executable somewhere under /nix/store/). To get dbus-update-activation-environment and the other binaries from the dbus package into the general path, one should add pkgs.dbus to the environment.systemPackages list in configuration.nix. (If using home manager, this might be accomplished by other means.)

Scenario:

On real hardware, I installed nixos with calamares but no desktop environment selected. Then, I proceeded with flakes and home manager proper configuration. Then I tried to follow the sway guide for home manager. It was then that I ran into this issue <https://discourse.nixos.org/t/wlr-errors-when-trying-to-start-sway/28698>. The solution of that thread worked for me.

So, I propose that <hardware.opengl.enable = true> to be added in the sway with home manager session,

To set up Sway using Home Manager, first you must enable Polkit in your nix configuration:

security.polkit.enable = true;

Additionally, you must enable opengl in your nix configuration //<<<<NEW LINE 1>>>>

hardware.opengl.enable = true; //<<<<NEW LINE 2>>>>

A general suggestion of 2 new lines can be seen above.

I just registered and I am new to nixos. I don't know the rules about editing the page, so I decided to post it as discussion first.

Hello RafTeog,

you can just start to edit the main page here. Its sometimes difficult to see whether a fix is just needed because you have some special circumstances. I am not a Sway user - maybe there are some circumstances where you dont need OpenGL, because you have an xserver enabled?

It may be a good way to just add a „Troubleshooting“ chapter and add your information about opengl and a link to the discource-discussion as a subsection. And: The troubleshooting chapter is already in this article. Maybe a subchapter like „Errors when trying to start sway?“.

Just start to contribute - have fun while doing it. Lets make this wiki ready for the 24.5 release together. Klinger (talk) 21:04, 2 May 2024 (UTC)Reply
