SimpleScreenRecorder indicator not displaying in Ubuntu 17.10

[Ads20000]

See https://plus.google.com/+PopescuSorin/posts/HhSFUy8Cqsf (will link this Issue there), is it possibly because XDG-CURRENT-DESKTOP is set as Unity and should be set as Unity:Unity7 as per this post? I can't find XDG-CURRENT-DESKTOP in the code though...

Ubuntu is doing some nonstandard stuff with the system tray. It's implemented by a Qt extension which translates the Qt systray API to the appindicator API which Ubuntu prefers. I did not implement this extension, it is just something that gets loaded automatically when you run SSR (or any other Qt program) on Ubuntu.

XDG_CURRENT_DESKTOP is an environment variable. You can see the current value in a terminal like this:

echo $XDG_CURRENT_DESKTOP

You can change it like this:

export XDG_CURRENT_DESKTOP="Unity:Unity7"

The change only applies to the current tab of the current terminal. You can run SSR from that terminal like this, to see if it fixes the problem:

simplescreenrecorder

If you want to make the change permanent, you should add the following line to your ~/.profile file:

export XDG_CURRENT_DESKTOP="Unity:Unity7"

After that you need to log out and log in again for the change to take effect.

Yeah sorry I should've commented quicker but wanted Popescu to comment for herself rather than speaking for her (some people would have something to say about that...) :/ I'm not sure this is the actual problem because it does work on Ubuntu 17.04 and the XDG_CURRENT_DESKTOP bug applies to 17.04 too but this bug is not occurring on 17.04. I've asked Popescu to file a downstream bug (Launchpad will pick up details about her system that may be useful) and then link it here.

Useful info, I didn't know about the Qt extension workings so thanks for that :)

I'm having the same problem under Ubuntu Mate 16.04, but the last time I used SSR the icon was showing OK!

This is what I get when I run SSR from terminal:

I don't think this is something I can fix in SSR, it's either a bug in the Ubuntu systray plugin, or a system configuration problem that is preventing SSR from finding the icons. This can happen with icon themes that forget to include a fallback to the 'hicolor' theme when they don't have a custom icon.

Also applies to Ubuntu 17.10 (with its modified GNOME session)

Installed Unity desktop on my Ubuntu Mate 16.04 and now it's not missing, but shows some sort of weird icon: Tried switching to other icon themes with no luck. Weird thing is It was working fine before, maybe something got updated on the repositories.

@MaartenBaert

@jhasse, 'AppIndicator/KStatusNotifierItem support for GNOME Shell' developer says that this is a bug in Qt, not in Ubuntu. I notice he's left a comment on a Qt bug about this so hopefully they'll respond...that was marked as a dupe though and the bug it was marked as a duplicate of is marked fixed...
