I am operating Insync in several computers (both Windows and Ubuntu) and some of these instances have problems on icon appearance.
The problem is simple: tray icon do not appear on Ubuntu 18.04.
Insync itself is running flawlessly according to reply from command line interface (sharing, downloading, uploading, …). And very curiously, this symptom happens on my two notebook machines; ThinkPad X220 and ThinkPad X1 Carbon (2015=3rd). Other Ubuntu 18.04 instance (desktop computers) have no problems on icon.
I wonder this trouble may be due to lack of some related packages … desktop computer has it (them) and notebooks not. Of course, as it is just my speculation, the cause may be different.
Is there any solution to detect the cause of problems, and even solve it ?
Thanks all for cooperation.
(Machine info) Two ThinkPads are dual-booting machine, Ubuntu and Windows. Ubuntu 18.04 and Windows 10. Both Ubuntu 18.04 instance is upgrade from 16.04.
I don’t install “AppIndicator Support” as mentioned in here. Instead, I use TopIcons Plus, a GNOME extension which maybe has similar function. Anyway, this extension has no effect for this problem (no change for enabling/disabling the extension).
