This is what I expected to happen. I kill and rerun nabi, bug is not occured.

I don't know what happens, but I think there are problem in new ubuntu splash.

I can confirm this bug. Exactly the same behaviour here - including the fact that killing nabi and restarting it resolves the issue.

Just upgraded to 9.10 today. This hasn't been fixed.

I can confirm this bug, too. Exactly same behaviour like the people here. I had to kill nabi and re-run to see it in the gnome panel. Otherwise, it is looking ugly by hanging around the gnome desktop. I have played around by modifying "/etc/X11/xinit/xinput.d/nabi" and "~/.nabi/config" without success.

[Soo-Hyun Choi (s.choi)]

Sorry, I have missed the information about my system. I am running Ubuntu 9.10 amd64 server edition (Linux 2.6.31-14-server), and the version of nabi that I'm using is 0.99.3-1. I've tried to install the latest one (nabi-0.99.4.tar.gz), but it wasn't helpful, either. :(

I did some experiments with nabi and notification applet. When I remove notification area from panel, it shows palette window even though I re-run the applet, it doesn't be embedded even though others are embedded correctly.

So, I did add some messages in nabi source to check what happens, and it seems that it doesn't receive any ClientMessage from root window. And there is other codes who does register filter and change event mask for receiving events.

It does call gdk_window_set_events(root_window, GDK_PROPERTY_CHANGE_MASK).

When I changed it to followings.

mask = gdk_window_get_events(nabi->root_window) | GDK_PROPERTY_CHANGE_MASK;
gdk_window_set_events(nabi->root_window, mask);

Then it works well. According to the manual of gdk_window_set_events(), it shouldn't disable ClientMessage because it doesn't have proper mask for ClientMessage. And also there is description, it will let it receive ClientMessage always whatever supplied mask is.

[MoonKyu Song (lanterrt)]

I referred the URL http://developer.gnome.org/doc/GGAD/sec-gdkevent.html.
And the description is following which is located on top of Table 3. Event Masks.

Selection, client, drag-and-drop, and delete events have no masks, because they are automatically selected (Xlib selects them for all windows).

How to fix this bug: (Thanks to MoonKyu Song)

0) Remove any previous "nabi" installation by doing "sudo aptitude remove nabi".

1) Download the latest nabi from http://kldp.net/frs/download.php/5287/nabi-0.99.4.tar.gz
2) Untar and unzip
3) Change "src/ui.c" as described below.

    $> vi src/ui.c +1052

    then, add/amend as the below:
    (I am going to modify "install_event_filter()" method in src/ui.c)

    int event_mask = gdk_window_get_events(nabi->root_window) | GDK_PROPERTY_CHANGE_MASK;
    //gdk_window_set_events(nabi->root_window, GDK_PROPERTY_CHANGE_MASK);
    gdk_window_set_events(nabi->root_window, event_mask);

4) then, configure and install

    $> ./configure && make
    $> sudo make install

    when configure, you may need to install "libgtk2.0-dev" and "libhangul-dev".
    this can be done by:

    $> sudo aptitude install libgtk2.0-dev libhangul-dev

As MoonKyu pointed out as the above, the bug was due to the fact that nabi accidently(?) disables a ClientMessage.

[dalfland (dalfland)]

Works like a charm!!!
thanks Soo-Hyun

Unfortunately, this didn't work for me.

Here is my install_event_filter():

static void
install_event_filter(GtkWidget *widget)
{
    GdkScreen *screen;

    int event_mask = gdk_window_get_events(nabi->root_window) | GDK_PROPERTY_CHANGE_MASK; // new, idea from launchpad

    screen = gdk_drawable_get_screen(GDK_DRAWABLE(widget->window));
    nabi->root_window = gdk_screen_get_root_window(screen);
    //gdk_window_set_events(nabi->root_window, GDK_PROPERTY_CHANGE_MASK);
    gdk_window_set_events(nabi->root_window, event_mask); // idea from lanchpad
    gdk_window_add_filter(nabi->root_window, root_window_event_filter, NULL);
}

Any ideas?

[Soo-Hyun Choi (s.choi)]

AlexE,

You should put "int event_mask...." after "nabi->root_winwow...." statement, something like the below.

static void
install_event_filter(GtkWidget *widget)
{
    GdkScreen *screen;

    screen = gdk_drawable_get_screen(GDK_DRAWABLE(widget->window));
    nabi->root_window = gdk_screen_get_root_window(screen);
    int event_mask = gdk_window_get_events(nabi->root_window) | GDK_PROPERTY_CHANGE_MASK;
    gdk_window_set_events(nabi->root_window, event_mask);
    gdk_window_add_filter(nabi->root_window, root_window_event_filter, NULL);
}

Guys, I made a nabi package for this bug fix.

http://pds16.egloos.com/pds/200911/06/58/nabi_0.99.4-1_amd64.deb

Soo-Hyun Choi 's patch did work! Thanks!

Now nabi is visible in notification area quite well.

Thanks Guys : )

[Alexander Eberspächer (alex-eb)]

Thanks, Soo-Hyun (수현 in Hangul?)! Works.

[Soo-Hyun Choi (s.choi)]

Hi,

We now have an official patch released by nabi development team:
http://kldp.net/tracker/download.php/275/100275/305368/453/nabi-tray-bug.diff

If you can't open the above URL, please take the attachment.

Cheers,
Soo-Hyun

The new bug fixed version 0.99.6 has been released.

You can download it here:
http://kldp.net/frs/download.php/5440/nabi-0.99.6.tar.gz

[Alexander Eberspächer (alex-eb)]

I changed the status to "Confirmed". I suppose that's the right status because so far, the patch has not been made available in the repositories.

[Kevin (kevinshlee)]

I'm wondering when I can get the fixed one from the repository.

[Soo-Hyun Choi (s.choi)]

The nabi dev team has updated the source code recently - you can download the latest tarball at http://kldp.net/frs/download.php/5440/nabi-0.99.6.tar.gz (this should be working fine). However, I am not sure when they will release/update the deb package in Ubuntu. In fact, I am not sure who is in charge of updating nabi package for Ubuntu.

Please report any problem directly to their project homepage at http://kldp.net/projects/nabi/ (more precisely here - http://kldp.net/projects/nabi/bugs).

[Changwoo Ryu (cwryu)]

0.99.6 has been in Debian/Ubuntu long ago. Yeah usually no one cares about it when it's fixed.
