I have the same problem. On a newly upgraded Ubuntu 18.04 with Gnome 3.28, the system menu on the right in the top panel is missing entries, if booted with an ethernet connection. If booted without ethernet (with or without wifi) all the entries are there.
Replicable: yes How to: Boot (or restart Gnome by Alt-F2, r, Enter) with the ethernet cable connected - icons are missing (see screenshot 1). Workaround: Boot (or restart Gnome by Alt-F2, r, Enter) with the ethernet cable disconnected - all the icons are there (see screenshot 2). Then connect the ethernet cable (see screenshot 3). This workaround is, however, not a permanent solution... ** Attachment added: "screenshot1.png" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774957/+attachment/5160286/+files/screenshot1.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774957 Title: Network icons in status menu disappearing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1774957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
