Broken system tray

[jazz4web]

Hello, everyone...

I use Debian sid with LXDE on board. After the last update I watch the broken system tray in LXDE panel. Look at this couple of screen shots.

If the screen resolution on my monitor is 1366X765 and the flag installed, there is no tray at all in the panel.

There is the next strings in run.log file:

** (lxpanel:1025): WARNING **: 08:10:08.357: task button : X error

Before the last update everything worked fine. Any help would be wonderful!

This is because Debian now compiles LXDE with GTK+ 3, even though not all components have been fully prepared for GTK+ 3 yet.

[jazz4web]

Okay, I understand... Thank you for your answer. The only question is will those components be fully prepared and if so, when? Or do I have to look for another solution for my desktop?

The only question is will those components be fully prepared

This is the plan.

and if so, when?

I can't tell you. Development capacity is limited.

[jazz4web]

OK. I love LXDE... So, I'll stay tuned! :)

Based on the discussion in Debian Bug 1052376, #38 may resolve this issue.

Thank you so much for LXDE!

Based on the discussion in Debian Bug 1052376, #38 may resolve this issue.

The mentioned commit just breaks things in a different way.

With that commit, while panel is set to 100% width, pager plugin covers (for example) systray and clock if they come after the pager.

Hello @jazz4web

The screen shot is broken, would you please upload again?

I just installed Debian sid, many things broken, systray however works.

Do you still have this issue? Do we mark it as closed?

[galtgendo]

The things rarely get fixed by themselves, so would you mind pointing out a commit made since I commented that would make a difference here ?

Cause I don't see it in this repo, at least not on master.

I'm not on Debian and my setup is pretty much as simple as it gets: lxsession, lxpanel, openbox (technically two monitors, but I keep one of them off most of the time - it's pretty small (by today's standards), so it's mostly good for triggering multi-monitor bugs).

Unless that #38 made a difference for that poster, but as I've said, that one just generates a different bug.

[jazz4web]

Do you still have this issue?

I do, I got used to this issue. So, the panel is still broken, because things rarely get fixed by themselves.

[kurokawachan]

Hello, do you have a screen shots?
I don't understand the problem.

Debian sid is not a stable debian. It highly likely not an issue from lxde.

I tried Debian sid and did not found this issue. Are you on latest release?

I am not sure if this issue is from two monitors. I set up a vm with two monitors, still not have this issue

[jazz4web]

Hello, do you have a screen shots?

No, sorry. My picture hosting is unavailable, I could not pay for the server. And I don't want to use any public picture hosting. Again, I am sorry.

Debian sid is not a stable debian. It highly likely not an issue from lxde.

Actually it is an LXDE issue starting from Debian trixie/sid, on Debian bullseye everything works fine.

I tried Debian sid and did not found this issue. Are you on latest release?

Debian sid is rolling. Yes, I upgrade it every 2 weeks. The issue is still there - panel is broken. It works almost fine, but looks awful.

Hello @jazz4web

It looks like it is a different issue from what it was first created?

It feels like this issue #76

Searching Debian Bug
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1052050

Would you have a look and see if this is the same?

[jazz4web]

Look here, my friend... This is my LXDE panel.

There is no flag, but there is the system tray. Now I put the flag.

Uh-oh... Where is the system tray? Nothing. That is it. I have nothing else to say.

[kurokawachan]

Thanks, now I understand what is going on. And I still believe it might be same issue in #76

I might be wrong, but I think inside the function panel_start_gui

https://github.com/lxde/lxpanel/blob/ffd815fc2d30a5fe339e5c927060a14cdc88e345/src/panel.c#L1666C1-L1673C13

before we use gtk_window_present

We should use gtk_window_set_default_size to set the width and height.

    /* window mapping point */
    p->visible = TRUE;
    _calculate_position(panel, &rect);
    gtk_window_move(GTK_WINDOW(panel), rect.x, rect.y);
    gtk_window_set_default_size(GTK_WINDOW(panel),rect.width,rect.height);
    gtk_window_present(GTK_WINDOW(panel));

It would fix the issue.

[jazz4web]

I am not a C-programmer. I don't know what is happening inside the black box of GTK. I just hope LXDE developers will change the situation till Debian trixie release. As I sad, I got used to this issue. It works almost fine, looks awfull. But LXDE is my favorite one, I don't want anything else, especially LXQt.

I just hope LXDE developers will change the situation till Debian trixie release.

That is the plan, time permitting.
