XPRA v4.4.6 not showing tray icons.

[nentibusarchitectura]

Describe the bug
In version 4.4.6 remote tray icons are not displayed any more it used to work fine until 4.4.5

To Reproduce
Run any application on the remote server that opens a tray icon, it is not displayed in the client, for example "keepassxc" or "systray-x" for Thunderbird, Remmina, etc.

System Information (please complete the following information):

• Server OS: Ubuntu 20.04.6
• Client OS: Ubuntu 20.04.6
• Xpra Server Version : 4.4.6
• Xpra Client Version: 4.4.6

Additional context
It was possible to download old versions of XPRA before in Ubuntu to downgrade if required but now only versions:

Version: 4.4.6-r29-1
Version: 3.1.5-r0-1
Version: 3.0.6+dfsg1-1build1

Are available now via APT

Would it be possible somehow to download the .debs for v4.4.5???

Please specify the exact desktop environment that you are using.
Ideally, please also include the client's output with -d tray.
The release notes for 4.4.6 clearly show some fixes for system trays:
https://github.com/Xpra-org/xpra/blob/v4.4.x/docs/CHANGELOG.md#446-2023-06-15
Perhaps using XPRA_USE_NATIVE_TRAY=0 would help?

Please specify the exact desktop environment that you are using.

Apologies, I completely forgot to mention desktop: XFCE v4.16

Ideally, please also include the client's output with -d tray.

Thanks, I will test your suggestions as soon as I get the chance.

Hi,

XPRA_USE_NATIVE_TRAY=0 set in the client as: in --env=XPRA_USE_NATIVE_TRAY=0 does not have any effect. Shall I set that up in the server too or setting it up in the client should suffice?

This is the output of -d tray

[totaam]

Apologies, I completely forgot to mention desktop: XFCE v4.16

That's a crucial piece of information.
This is not the default DE on Ubuntu.

set_icon_from_file(xpra.png) tray_widget=<AyatanaAppIndicator3.Indicator object at 0x7f0d95fd2e80 (AppIndicator at 0x1550b50)>

So you're using AyatanaAppIndicator3.
Perhaps the fixes for KWin broke XFCE: #3789
I would have expected XPRA_USE_NATIVE_TRAY=0 to revert back to the old behaviour.

[nentibusarchitectura]

Upgraded client side to v5.0.0, tray icons still not working.

[totaam]

As per https://github.com/Xpra-org/xpra/wiki/Platforms, XFCE on Ubuntu is Tier-3.
I do not have the time to investigate this, sorry.

At this point how much I dislike gnome can't be put on words... I understand this is not xpra's fault, gnome still refuses for no good reason to support tray icons.

sudo dnf install gnome-shell-extension-appindicator gnome-extensions-app

Ran:

gnome-extensions-app

Enabled the appindicator extension so I can get icons on gnome

Rebooted

Ran XPRA aggain attaching to my server (Server runs Ubuntu 20.04)

Tray icons do not show using xpra 4.4.6 on Fedora 38 either, all I see is XPRA's icon in the tray area but nothing from the server. (attached screenshot, note most of the menu is also non-functional but this is a different story)

Found in your log:

• --encoding=rgb - usually a terrible idea, don't do that
• --compress=9 - just as bad

My guess is that you want --quality=100.

---

At least you managed to enable the extension!
On my Fedora desktop, you can't: no errors, no feedback, it just cannot be enabled.
I have very little time to devote to things that Gnome seems to break intentionally.
In any case, the appindicator "tray" implementation is incapable of forwarding regular X11 trays properly as it's limited to showing a menu and X11 trays are not. So even if it did somehow run, it would be mostly useless for forwarding.
Try MacOS or MS Windows as clients, those have not broken their tray API (for almost 30 years in the case of win32).

Some pointers:

• 928647c
• StatusNotifierItem support #2161 (comment)
• fix appindicator so we can use it for forwarding system trays #406 (comment)
• Submenus of the tray menu are broken #3800 (comment)

[totaam]

I managed to enable it in the end, and tried to make it easier / automatic for others to do so when installing xpra-client-gnome: #2197 (comment)

note most of the menu is also non-functional but this is a different story

Rather than figuring out which version of appindicator broke this (upstream doesn't seem active), I ended up changing when and how we generate the menu to workaround the issue.

---

As for system tray forwarding... like I said above, use an OS with a usable API 😞
So I think I will close this ticket as wontfix / cantfix because no API exists to provide a "real" system tray on gnome-shell.

[nentibusarchitectura]

Found in your log:

* `--encoding=rgb` - usually a terrible idea, don't do that

* `--compress=9` - just as bad

My guess is that you want --quality=100.

Interesting.

Why these seemingly horrible settings end in people's configurations is because at some point in the past it fixed some issue real or perceived. XPRA for me is a god send, it is the best thing since sliced bread to work remotely but it broke often in the past, and when it did I had to find a way to make it work with my poor understanding as an end user and what I could find online at the time.

These settings are the result of tons of experimentation, I have been using them since v3.x and these allowed me to work with as little latency and as reliably as I could (same as with the 8 bit encoding I often use and that you so kindly fixed back on 4.4.5).

I will experiment with --quality=100, I appreciate your suggestions a lot.

I hate Gnome with a passion, I only deployed it because you mentioned that Fedora is supported, but I don't want to use Gnome, believe me I would prefer to chew glass instead.

Regarding the client I can't use Windows, and I can't use Macs either, I need my Server and Client to be Linux, I don't care too much about the distro, but it has to be Linux, so if troubleshooting in Fedora is better for you I can make the effort to move to Fedora and troubleshoot there.

As per tray API support XFCE (and MATE) has had stable tray support for years and it has been working with XPRA since v3 which is when I started using XPRA on pretty much any distro, the tray broke from 4.4.6 onwards, it was running fine in 4.4.5.

All this time I have been on Ubuntu and the tray worked fine all these years, I haven't changed or updated the OS or desktop in the client, the tray broke with XPRA v4.4.6.

If I deploy Fedora with XFCE, could or would you please be able look into the tray issue?

At this point I'm even willing to sponsor/donation for the work, I really need the tray icons... it is a pain not being able to see the tray icons for my work.

[totaam]

is because at some point in the past it fixed some issue real or perceived

Could well be real, in some rare specific cases, it is the correct solution.
The problem comes from people blindly copying command lines from the interwebs, which is perpetuating the idea that tweaking --encoding= is good idea - it very rarely is.

the tray broke from 4.4.6 onwards, it was running fine in 4.4.5

Then it should be fixable. From the 4.4.6 changelog:

• 25302e1
• 0a1819f
• 55608da
  It's very likely to be one of these 3.

[nentibusarchitectura]

I have been doing some testing

I deployed all the build tools, dependencies, etc to build XPRA on Fedora 38 and deployed XFCE 4.18 (standard on F38)

The tray icons works until commit: 15062ac (but the main menu does not.)

The tray stops working from commit: 5acbde2 onwards.

• 25302e1 : running with XPRA_USE_NATIVE_TRAY=0 should have the same effect and disable appindicator (though this may also break xpra's own system tray - assuming that this one was working?)
• 0a1819f is suspicious, you're running an X11 desktop and perhaps appindicator is not a good choice there, so again, setting XPRA_USE_NATIVE_TRAY=0 might help going back to using Gtk.StatusIcon
• 55608da - I doubt that XFCE is detected as Wayland, but who knows?

In my case, with a gnome-shell desktop under Wayland, trying to use Gtk.StatusIcon does not work at all, for anything - no errors, but nothing is shown anywhere, hence why we don't use it.

Since the code says:

xpra/xpra/platform/posix/gui.py

Line 116 in 3b9f2be

#could restrict to only DEs that have a broken system tray like "GNOME Shell"?

I've implemented something simple along those lines in 1f32121.
Does that restore the system tray under XFCE?

[nentibusarchitectura]

I've tried to compile 1f32121 but I get the following message when I try to connect to the server:

The latest commit I can compile that doesn't exhibit this "connection error" issue is:

b0c3ced2ea3217ee3d35f15c746ec59ffee09ec3

(The connection error start to appear in commit: 4310795 I think)

And the good news is that on that commit (b0c3ced) if I use XPRA_USE_NATIVE_TRAY=0 the tray works again with XFCE :-D (doesn't work without it)

Regarding what XFCE uses for the systray the xfce4-statusnotifier-plugin

Which according to XFCE's docs implements the freedesktop standard:

The xfce4-statusnotifier-plugin provides a panel area for status notifier items (application indicators). Applications may use these items to display their status and interact with user. This technology is a modern alternative to systray and follows the freedesktop.org specification regarding status notification.

Not sure if this could be of help, Gnome is garbage when it comes to the systray, but I guess all the other desktops use the standard, the systray works fine on XFCE, MATE and KDE.

Thanks again for all your support with this and patience, I'm not a dev and all of this gets complicated for me.

I've tried to compile 1f32121 but I get the following message when I try to connect to the server:

That's a WIP, either use the latest html5 client with it or wait for the final release.

if I use XPRA_USE_NATIVE_TRAY=0 the tray works again with XFCE

Well, that's odd. This switch makes xpra use Gtk.StatusIcon and not appindicator!

OK, so I've changed it to only use appindicator on X11 gnome: 8deb2da

This will be included in v5.0.2
