Dear all,
I use SDDM with (display-server "wayland"), and Sway as my main
window manager.
My current configuration files are here:
- system configuration:
https://gitlab.com/wehlutyk/guix-config/-/blob/master/config.scm
- main profile:
https://gitlab.com/wehlutyk/guix-config/-/blob/master/sl-manifest.scm
- dot files: https://gitlab.com/wehlutyk/dotfiles
I've been struggling to get the DBUS_SESSION_BUS_ADDRESS variable
to be set by SDDM, as it does not seem to set it by default. The
current script that SDDM runs before starting Sway is
https://github.com/sddm/sddm/blob/master/data/scripts/wayland-session
, and I haven't found any other setup step which might be a source
for enviroment variables inside Sway.
(Somehow environment variables set in
`.config/environment.d/*.conf` also get set, but I don't know how
or where that happens.)
In the default configuration, DBUS_SESSION_BUS_ADDRESS is
therefore not set inside Sway, which leads to a number of problems
(e.g. nautilus can't read the Trash system).
One can set the value of DBUS_SESSION_BUS_ADDRESS produced by
`dbus-launch --sh-syntax` in `.profile` (
https://gitlab.com/wehlutyk/dotfiles/-/blob/master/.profile#L9 ),
which is then sourced by `wayland-session` if the shell is bash.
In my case my shell is fish, and the way `wayland-session` calls
fish doesn't make it export the variables exported by `.profile`.
For that a small patch to `wayland-session` works, which I ended
up using:
https://gitlab.com/wehlutyk/guix-config/-/commit/5105ab1bea7f8233de5dffc053f794ae69822acd
With the two changes above (setting DBUS_SESSION_BUS_ADDRESS in
.profile, and patching wayland-session), apps can connect to dbus
inside Sway. But this seems extremely hacky. Is there maybe a
better way to make sure SDDM+Sway(+fish) is set up properly as a
desktop enviroment? Is it time to make a
`sway-desktop-service-type`?
Happy hacking,
Sébastien
