[linux] setting icon works, but only sometimes

[jakub-stefaniak]

Hey, I ran into an issue testing the example project on a virtual machine running Ubuntu 20.04.3 LTS.

I tested the app on 2 virtual machines on different PCs. One works like a charm and the other one shows the tray icon only sometimes.

I tried launching the example app from the terminal on the problematic vm to see logs, and it throws:
GLib-GIO-CRITICAL **: 16:15:43.425: g_dbus_proxy_new: assertion 'G_IS_DBUS_CONNECTION (connection)' failed
whenever I try to set the tray icon.

One PC has Intel CPU and the second one has AMD CPU. I don't know if that's relevant, but it works as expected on intel.

This might probably depend if you flutter app is running on wayland or X11.
You can try to start the app with GDK_BACKEND=x11. Obviously, x11 should not be use anymore.
