Bug 22218

There has been no update of drakx-net since August 1, so something else broke your session. What's your desktop environment? GNOME, Plasma, ...? I cannot reproduce your issue using Plasma on Mageia 6 and drakx-net-2.32.1-1.mga6.

Hi,

Thanks for your quick answer.

Sorry for forgetting system info. Here they are :

kernel : 4.9.56-desktop-1.mga6 #1 SMP Thu Oct 12 22:55:31 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Using KDE environment :
plasmashell 5.8.7
KDE Frameworks : 5.32.0
Qt : 5.6.2

I haven't installed anything manually and I haven't changed anything in configuration since months.


I have noticed that drakx-net is unchanged.
So I suppose there is some interaction with one of the other updates.
That's why I give the list of recent ones.

I notice than the update just prior the list I gave concerns graphic driver :

But I'm pretty sure it works more recently.

Note that all the other icons correctly show menu when right-clicking on them.
That's made me choosing drakx-net package for the bug report :).

I am seeing this on one of my M7 Plasma installs. Hardware: i5-2500, 16GB RAM, integrated Intel graphics, wired Internet connection. 

This is my main production install, used on a daily basis, and fully updated. I don't often use the net_applet context menu, so I have no idea how long this has been in effect. I only tried it because another user from Usenet complained of the same problem.

I tried creating a new user on this install, and he is also affected. However, another Plasma install on the same hardware, used primarily for testing purposes, also fully updated, DOES have a working net_applet context menu. Unfortunately, I'm not seeing it on other Plasma installs on other hardware, either, indicating it's going to be VERY difficult to duplicate.

Changing the version to 7, since M6 is EOL.

Version: 6 => 7

I am also affected by this strange behaviour from net_applet.

Right after startup, his logo is OK. No right-click menu available.
If I kill it and restart it from a console, right-click is available.

Therefore, when right-click menu is available, sub-menus are displayed in wrong direction at first (ie) where display finished. Subsequent hovering the cursor on these menus, subs menus are displayed correctly.

Bug is present, whatever connection is in operation.

Also, in console, after relaunch net_applet, I can see these logs:

I do not have this problem now but remember having experienced something like this in the past.

I run Plasma. I note that the right click menus for different icons for me appear at two different places, either at cursor, or at edge of tray. ( And one is a bit strange: Nextcloud menu starts one menu height too high if and only if panel is at bottom) 

What i mean is there may be some quirk possible to play with:

Try if it works when the panel is at other edges of screen?

Hello Morgan,
At other edges of screen, net_applet has same behaviour. I must relaunch it in order to have right-click menu.

I also remarked same behaviour for mgaapplet.

Just after system boot and log on my account, I would like to right-click on mgaapplet. I could not get it functioning by the time it waits to look for updates  (when icon is orange with 2 arrows).

Just after mgaapplet is ready (blue icon with tick or updates available), right-click is possible and I get a menu under mouse cursor on desktop.
---------------------------------------------

To return to net_applet, after system boot and log on to desktop, network is running and functioning.
If network is disconnected (unplug wire from computer for Ethernet OR switch off WiFi Network on my Freebox), net_applet reacts, change his status, right-click menu appears magically! Network is reconnected and right-click menu is still available for the rest of session.

I will publish tomorrow a video showing the bug.

Created attachment 11761 [details]
net_applet no right click menu after boot

This is a short video make with peek.

You can see that net_applet has no right-click menu functioning after system boot.
It runs fine after unplugg/pluging wire connection.

(or "killall net_applet" and do "net_applet &" in Konsole)

Regards,

In Plasma session (Plasma 5.19.5, Mageia 8 B1 Cauldron),
Each attempts to right-click on net_applet after booting result in journal output:

plasmashell[2326]: Could not find DBusMenu interface, falling back to calling ContextMenu()

But menu does not appear. It does if connection is dropped, or activate/deactivate one.

I cannot reproduce this problem using Plasma and Mageia 7. I didn't try with Cauldron. How long do you wait between login and right-clicking on the icon?

CC: (none) => LpSolit

Doesn't seem to matter on my affected machine. Right after the boot, or hours after, same thing.

It's interesting to watch, though. After the boot, right click on the icon once, nothing. Left click, and the Network Center comes up. Tell it to disconnect from the wired connection, and as soon as the icon changes, the context menu pops up - without right-clicking a second time. Reconnect, and from then on the context menu pops up with every right-click.

Interesting. The problem you describe was supposed to be fixed by a commit I did in 2017 in both net_applet and mgaapplet. Could you test something for me? In /usr/bin/net_appplet at line 314, increase the value of the timeout from 100 (milliseconds) to something bigger, e.g. 1000 or 5000 (i.e. 1 or 5 seconds) and see if this fixes the problem for you. This is the last line of the code below:

# NOTE: Must be called after checkNetworkForce() above to make sure that
# the menu has already been created, else set_context_menu() will complain.
# When net_applet is launched automatically when opening a new session, there
# seems to be some latency with DBus and/or DBusMenu, and when this method
# is called too early, it seems to be blocked. So we add a timer here to call
# it again to make sure that right-click events will be correctly handled by
# DBusMenu.
Glib::Timeout->add(100, sub { $icon->set_context_menu($menu); 0 }) if $is_sni;

M8 + Plasma 5.20.4 x86_64
WiFi configured within DrakX when installing.

First boot: net_applet gives a green WiFi icon. Connection is OK.
No right-click menu.
Seen in a Konsole with "journalctl -f" when right-clicking:

janv. 20 13:34:33 mageia.local plasmashell[2392]: Could not find DBusMenu interface, falling back to calling ContextMenu()

So, I think there is a race condition when user logs on: SNI is not available when net_applet starts. But it is available later.
Killall net_applet and do $ net_applet & and you have the right-click context menu and no longer this above notification.

I think the issue is that /etc/xdg/autostart are all loaded at the same time and there is a race to expose to dbus the notification system

/etc/xdg/autostart/xembedsniproxy.desktop is loaded at the same time that

/etc/xdg/autostart/net_applet.desktop

Keywords: Triaged => (none)
Source RPM: drakx-net-2.51-1.mga8.src.rpm => drakx-net-2.54-1.mga8.src.rpm

I added :
Glib::Timeout->add(100, sub { $icon->set_context_menu($menu); 0 }) if $is_sni;

to

Glib::Timeout->add(5000, sub { $icon->set_context_menu($menu); 0 }) if $is_sni;

and rebooted. No change.

Note:
If Plasma has systemsettings5 => Startup and Shutdown => Desktop Session set to "Restore previous session"
AND you have done killall net_applet && net-applet &, you do have the right-click menu upon logon.

If it is set to "Restore previous session" WITHOUT killall blabla => NO right-click menu.

If it is set to "Start with an empty session" => NO right-click menun even if you did killall blabla last session.

Yes, my affected system is set to "Start with an empty session." But so are my other systems, and none of them are showing this. Speculation follows:

The affected system has / and /home residing on an ssd, while an unaffected system on the same hardware resides on a rust drive. 

The affected system, with a i5 2500, is my fastest hardware.

All of the other unaffected hardware is connecting via wifi, so they show a different icon in the panel. Some have / and /home residing on an ssd, others only have rust drives.

I'm wondering if the above differences, which would result in differences in timing, might explain why there might sometimes be a race condition and sometimes not.

My 2 cents on this bug:

It is a race condition: KDE startups immediately setting ENV variables as
KDE_FULL_SESSION and XDG_CURRENT_DESKTOP=KDE and launching immediately all
/etc/xdg/autostart/*.desktop files.

BUT SNI (KDE system notifications) is not immediately available.
You can even see it by complains about own Plasma/KDE umbrella Applications in system log:

DiscoverNotifier[2262]: kf.notifications: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP

korgac[2285]: kf.notifications: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP

So, there is a bug against kf.notifications.

net_applet wants a SNI available and DBus Connections on it.

You can even see this complain about plasmashell:
plasmashell[2243]: DBusMenu disabled for this application

It is the only DBus application on this system.
Later, when you try a right-click you got:
plasmashell[2243]: Could not find DBusMenu interface, falling back to calling ContextMenu()

Looking at upstream bugs reports about systray: Theses two should be looked:
1) https://bugs.kde.org/show_bug.cgi?id=383202
2) https://bugs.kde.org/show_bug.cgi?id=425315

But, the listIcons.sh script proposed at 2) above correctly lists net_applet as registered KSNI client. So it is not 2) a good candidate.

1) System tray icon's context menu isn't updated properly in plasma/x11
Bugreport upstream has a potential fix for Plasma there.
Ping Nicolas L.

Note that https://bugs.kde.org/show_bug.cgi?id=383202 is fixed upstream for Plasma 5.22 release.

But, I do think this issue is still valid, something prevents net_applet to export his menu through a dbus connection.
