snixembed - proxy StatusNotifierItems as XEmbedded systemtray-spec icons
INFO: recent electron versions supports XEmbed tray icons again for now. This means snixembed is of limited use. It will however be maintained in case electron or other software eventually drops their XEmbed support again.
Previously, electron dropped support for the old XEmbed-based system tray protocol, while many status bars for simple X window managers still do no not support newer protocols like StatusNotifierItem. This project is basically a dirty hack using deprecated GTK+ StatusIcons to proxy this new specification to the old one.
As newer electron versions support the old XEmbed-based tray icons again, snixembed is currently not very useful, unless you rely on those old versions. (or rely on chromium tray icons, which still only support StatusNotifierItem) Most other software supports XEmbed icons as a fallback.
While snixembed works fine with most setups, some bars and DEs provide their own optional SNI support, which should be preferred when available.
Currently supported:
This is enough for electron apps like Riot and Signal, and also for most Qt apps as the list above includes all functionality QSystemTrayIcon permits. Please see the known issues and issue tracker if an app doesn't work properly.
¹: so-called AttentionIcons and OverlayIcons are not supported, but I have yet to encounter software that uses this part of the spec. Qt does not support it.
Simply launch snixembed to start watching for icons.
Some applications only present a tray icon if snixembed is available on start.
For autostarting, use snixembed --fork before starting SNI applications to
avoid race conditions. This will fork once the service is running. (e.g. in an
.xinitrc, use snixembed --fork instead of snixembed & before tray apps)
Issues are tracked on sourcehut: ~steef/snixembed. There's a Matrix room at #snixembed:matrix.org for discussion and support. Come say hi!
These should be packaged in most major distributions.
Simply run make to build and if desired make install to install, by default
to /usr/bin/snixembed.
There are AUR packages available: stable and development.
For Gentoo/Portage, powerman made an ebuild.
For Void Linux, it is packaged by projectmoon.
ayatana/libappindicator seem to think their standard is supported when they see the service, and then start talking appindicator to it. Therefore they do not fall back to XEmbed specification, and snixembed gets a load of AppIndicator jargon thrown at it. Currently, snixembed can handle basic AppIndicator functionality (icons and menus), and may support more in the future. But not everything works. Feel free to report issues to the tracker.
As a workaround, you may start such applications with their own D-Bus
session bus. They will be unable to communicate through D-Bus with the
outside world, and therefore they won't find snixembed and fall back to the
XEmbed tray icon. To do this, execute application like this:
dbus-launch --exit-with-session <application>.
As already mentioned, this will only work for apps that don't heavily rely on other services on the session bus for functionality. Examples that have been tested to work are discord and skypeforlinux.
Alternatively, one could also choose to run snixembed on a separate session
bus, and let all SNI-only apps run on that session bus too by running
dbus-daemon --session --print-address and then setting the environment
variable DBUS_SESSION_BUS_ADDRESS to the address printed by dbus-daemon
for all applications that have to communicate with snixembed. This will
isolate snixembed and those applications from the rest of the D-Bus world.
As the author does not really use any non-SNI applcations, this is not well
tested or supported, but I'm happy to assist anyone going this route or look
into contributions that make this easier.
some apps probe for StatusNotifierItem support not by checking for the D-Bus
service but by checking environment variables. Exporting
XDG_CURRENT_DESKTOP=KDE and KDE_SESSION_CURRENT=5 seems to do the trick.

This error could mean that no XEmbed tray is present.
