[Linux] [Ubuntu 16.04] No tray icon in Xenial

[stephen-d-hill]

Expected behaviour

To see icon

Actual behaviour

No icon

Steps to reproduce

Install owncloud client

Client configuration

Client version: 2.1.1+dfsg-1ubuntu1

Operating system: Xubuntu 16.04

OS language: English UK

[guruz]

What do you see instead? Can you run the client as owncloud --logfile - and paste the output? Which Qt version?

[stephen-d-hill]

The owncloud main window works fine, just no notification icon. I am unsure how to find out my QT version.

logfile - owncloud_logfile.txt

[guruz]

Thanks, the logfile mentioned it.. Using Qt 5.5.1

Is there nothing before that in the log?

@ckamm @danimo maybe you know more about those tray issues..

[stephen-d-hill]

Used --logfile instead of --logwindow this time - owncloud_logfile1.txt

[guruz]

Maybe this in Qt 5.6 helps..

    dbustray: Implement better detection of indicator-application

    We need to do the icon cache trick all desktops using indicator-application,
    these are not limited to Unity. For example, the default Xubuntu and Lubuntu
    desktops use indicator-application too.

    Without this, tray icons will be improperly shown on these desktops.

    dbustray: Support late registering of tray icon menu

    If a menu is added to the tray icon after the icon itself has been registered,
    we need to register the menu properly.

    This method can be called for a submenu after it's called for the top-level

[scroom]

Can I provide more info? I'm as well experiencing this bug.

[danimo]

I now upgraded to 16.04 and the packages and I can confirm above findings. The workaround for now is to use the Ubuntu 15.10 packages provided by us. Those still are Qt4 based but solve the problem.

[danimo]

I filed https://bugs.launchpad.net/ubuntu/+source/owncloud-client/+bug/1573639 with Ubuntu.

[danimo]

This must be a special bug related to the way we rebuild the System tray. A trivial example works just fine.

#include <QApplication>
#include <QSystemTrayIcon>
#include <QImage>
#include <QPixmap>
#include <QMenu>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QImage img(64,64, QImage::Format_ARGB32);
    img.fill(Qt::red);
    QSystemTrayIcon sti(QIcon(QPixmap::fromImage(img)));
    QMenu *menu = new QMenu();
    menu->addAction("Foo");
    menu->addAction("Bar");
    menu->addSeparator();
    QMenu *submenu = new QMenu("Sub Menu");
    submenu->addAction("Bleh");
    menu->addMenu(submenu);
    menu->addSeparator();
    QObject::connect(menu->addAction("Quit"), SIGNAL(triggered(bool)), &a, SLOT(quit()));
    sti.setContextMenu(menu);
    sti.show();

    return a.exec();
}

[danimo]

We know, please do not post any +1's. We are working on a solution to the problem.

[ogoffart]

I was able to locate the problem. The problem is in ubuntu's "appmenu-qt5" and is a bug that cause our call to QSystemTrayIcon::isSystemTrayAvailable() to remove the icon.

That's because appmenu-qt5 seems to assume there is only one QPlatformSystemTrayIcon while there can be one per QSystemTrayIcon. in particular, QSystemTrayIcon::isSystemTrayAvailable creates a temporary one, and when it gets distroyed, it unregister the dbus object for the existing systray.

[guruz]

FYI @mitya57

[mitya57]

Thanks @guruz for pointing me to this, and thanks to @ogoffart for narrowing down the problem.

Appmenu-qt5 is dead, and we want to remove it from Ubuntu as soon as our Qt is updated to 5.6 (which has native support for D-Bus trays and global menus). However, provided that 16.04 is an LTS release, it may make sense to get the appmenu-qt5 bug fixed there. I will add it to my list, however I have very few time, so I don't know when I will be able to get to it. Merge proposals against lp:appmenu-qt5 welcome, of course :)

[guruz]

@mitya57 thanks for the reply :) Then we need to workaround it from our side. XDG_CURRENT_DESKTOP should be Unity on 16.04?

[nazar-pc]

Yes

~>  echo $XDG_CURRENT_DESKTOP 
Unity

[mitya57]

$XDG_CURRENT_DESKTOP depends on environment, but it's not related to this bug.

For workaround on your side, try checking for $QT_QPA_PLATFORMTHEME and unsetting it if it's equal to appmenu-qt5 (before constructing the QGuiApplication).

[ogoffart]

I reported the bug to appmenu-qt5: https://bugs.launchpad.net/appmenu-qt5/+bug/1574699

[ogoffart]

Also another way to workaround the problem is to run owncloud with --platformtheme=generic command line option

[dragotin]

Ok, I think we can live with the workaround mentioned by @ogoffart and document that very prominentely.

We should continue to work with Ubuntu to help them fixing that as good as we can, @ogoffart already created the bug report.

@jnweiger could we add a start script that calls owncloud with parameter --platformtheme=generic with affordable effort to the package?

[rhersel]

@ogoffart This workaround does not work for me: --platformtheme is an unknown option for /usr/bin/owncloud on Ubuntu 16.04 with owncloud-client installed from Gnome-Software.

[ogoffart]

@rhersel works fine here with the owncloud client installed from whatever apt-get install owncloud does. If --platformtheme is an unkown option that might mean that owncloud was compiled with Qt4 instead of Qt5?

[ogoffart]

Workaround pull request for 2.2: https://github.com/owncloud/client/pull/4747

[ogoffart]

I tested the qt4 version on ubuntu, and it works well.

[stephen-d-hill]

Performing

sudo apt-get remove appmenu-qt5

works for me :)

[step4wd]

Running owncloud --platformtheme=generic gives the following output:

Unrecognized option '--platformtheme=generic'
Try 'owncloud --help' for more information

I tried sudo apt-get remove appmenu-qt5 also but didn't help.

[ogoffart]

@step4wd then you are using the Qt4 version. The Qt4 version works for me. What is your problem exactly? Which owncloud package are you using?

[step4wd]

@ogoffart I installed owncloud-client which comes with Ubuntu 16.04 as it is.

[oserban]

The default owncloud client on Ubuntu Xenial (as returned by owncloud --version) is: ownCloud version 2.1.1 Using Qt 5.5.1

[s-light]

for me its the same:

stefan@stefan-latitude:~$ owncloud --platformtheme=generic
Unrecognized option '--platformtheme=generic'
Try 'owncloud --help' for more information
stefan@stefan-latitude:~$ owncloud --version
ownCloud version 2.1.1
Using Qt 5.5.1
stefan@stefan-latitude:~$ owncloud --help
ownCloud version 2.1.1
File synchronisation desktop utility.

Options:
  -h --help            : show this help screen.
  --logwindow          : open a window to show log output.
  --logfile <filename> : write log output to file <filename>.
  --logdir <name>      : write each sync log output in a new file
                         in folder <name>.
  --logexpire <hours>  : removes logs older than <hours> hours.
                         (to be used with --logdir)
  --logflush           : flush the log file after every write.
  --confdir <dirname>  : Use the given configuration folder.

For more information, see http://www.owncloud.org

my system is an Kubuntu 16.04 64bit

[jmfrappier]

Same thing as @oserban and @step4wd with version and error launching owncloud --platformtheme=generic Just launching owncloud still works as i sometimes get a notification that some files have been copied.

[Steve-3d]

I got the error with the unsupported command line option, too - but doing export QT_QPA_PLATFORMTHEME=generic before starting owncloud as usual works now and I get the icon back.

[step4wd]

@Steve-3d it worked for me. Now how to make owncloud always launch this way on startup? This is changing an environment variable which assume will effect other apps also.

[Steve-3d]

I created a little script for this:

#!/bin/bash  
QT_QPA_PLATFORMTHEME=generic  
/usr/bin/owncloud

This sets the variable only for the current shell process and does not modify anything else. Then I did a chmod +x ownCloudScript.sh and added it with full absolute path into the start programs tool to let it always run on login. I hope this helps :)

[rhersel]

The above script works perfectly for me. Thank you

[frederikbosch]

And modify your startup file.

sudo nano /usr/bin/owncloud-tray-fix
sudo chmod +x /usr/bin/owncloud-tray-fix
nano ~/.config/autostart/owncloud.desktop

Modify the Exec line as foloows.

Exec=owncloud-tray-fix

[VNovotna]

Running owncloud like this env QT_QPA_PLATFORMTHEME=generic owncloud is even easier.

[didubu-fr]

Hello, They solved the problem at Ubuntu, a new package was released in Yakkety and Xenial proposed : https://bugs.launchpad.net/ubuntu/+source/owncloud-client/+bug/1573639/comments/11 Thanks !

[geez0x1]

Has anybody tested this on Debian 8 (stable/jessie)? I just installed client 2.2.0 and the icon has disappeared.

[nazar-pc]

Funny, but it just appeared with 2.2.0 update on Ubuntu:)

[etamme]

I am not sure ... but this may have broken the system tray icon for my 14.04 installation. Here is a gist of my apt-history for the day:

https://gist.github.com/etamme/9e547c536b44f7a3f2b0998b8765bd94

Basically now the systray icon is in the very top left of my screen and appears "on top" of any window.

[nazar-pc]

There was such bug some long time ago, like 1.5 years or so.

[etamme]

So yea I saw that when I was searching, but this morning my systray icon was fine, but after I installed the updates in the linked gist, the owncloud systray icon got messed up.

[Niyes]

In Debian 8 (Jessie) missing tray icon after update to the 2.2.0 version :(

[cmburg]

Same in elementary OS 0.3 (64bit) (32 bit not tested yet but had not problems at all IIRC)

[DroWnThePoor]

I'm having this problem as well.No tray icon at all since last 2 updates. I have another machine running the client before the updates and it works perfectly. I was wondering what exactly I'd need to do to transfer that version of the client from one Ubuntu install to another? Can anyone advise me?

[tony5]

@DroWnThePoor

It has already been acknowledged that there is a bug and a work around has been posted.

Ubuntu 16.04 / client Version 2.2.0%nil (build 1605) Using Qt 5.5.1 = no tray icon with gnome desktop.

The client still works without the tray icon but if you need it then the commands posted above will work.

You can adjust the program startup or manually run the bellow command in a terminal.

~$ killall owncloud && nohup env QT_QPA_PLATFORMTHEME=generic owncloud >/dev/null &

[mitya57]

I have created a proper fix for this bug in appmenu-qt5. While I'm waiting for a review I have uploaded the package with this fix to my PPA so that you can test it.

Commands to get the package from my PPA are:

sudo add-apt-repository ppa:mitya57/ppa
sudo apt-get update
sudo apt-get install appmenu-qt5

Please test and give your feedback.

[tony5]

@mitya57 did not work for me, maybe I did it wrong. I did not add the ppa but installed appmenu-qt5_0.3.0+16.04.20151130-0ubuntu1+ppa1_amd64.deb from your link removing appmenu-qt5 all together will work or adjust start up ~$ killall owncloud && nohup env QT_QPA_PLATFORMTHEME=generic owncloud >/dev/null &

I also have no idea why the issue is marked closed?
