I upgraded my Ubuntu 17.10 install to 18.04 yesterday, and I'm noticing that I don't have any AppIndicators anymore. Here's what I tried that didn't work:
- Enable
Ubuntu AppIndicators
in the gnome tweak tools - Enable
Ubuntu dock
in the gnome tweak tools - Installed the
KStatusNotifierItem
gnome extension. It fixed the issue for a few minutes, then upon reboot the icons disappeared again and reinstalling it didn't work.
Thanks!
