GdkScreen with no is_composited

[Shayne]

I get the following error on a fresh install on Debian etch:

Exaile 0.2.12devel
Traceback (most recent call last):
  File "/usr/local/lib/exaile/xl/gui/main.py", line 1398, in __on_volume_changed pop = xlmisc.get_osd(self, xlmisc.get_osd_settings(self.settings))

    if screen.is_composited():
AttributeError: 'gtk.gdk.ScreenX11' object has no attribute 'is_composited'
Introspect error: The name org.gnome.SettingsDaemon was not provided by any .service files

I'm running XFCE and I have gnome-control-center installed. The splash screen does show up but crashes quickly after.

The following error is still showing up:

Introspect error: The name org.gnome.SettingsDaemon was not provided by any .service files

Does this have to do with python-dbus? See bug #138930

I currently have python-dbus - 0.71-3 and gnome-control-center 2.14.2-7

It might be related to dbus or gnomecc (if you're running XFCE, chances are the gnomecc settings daemon isn't even running), but it's not the problem that caused Exaile to not run.

I just realised that the fix I committed may have nothing to do with this, so if Exaile still doesn't run, please reopen and attach the complete console output.

[Shayne (shaynetonio)]

The only error I get is:

Introspect error: The name org.gnome.SettingsDaemon was not provided by any .service files

The no_composited issue is no longer showing up so I'm assuming that it's fixed. I'm suspicious that gnome-settings-daemon is even running but whether that is the problem is beyond me

[Johannes Sasongko (sjohannes)]

The whole console output would be great to have, as right now I don't know what's wrong.

[Shayne (shaynetonio)]

I don't really see a verbose option, so the output isn't much:

==
shayne@MILOU:~$ exaile
Exaile 0.2.12devel
Introspect error: The name org.gnome.SettingsDaemon was not provided by any .service files
shayne@MILOU:~$

[Johannes Sasongko (sjohannes)]

Oh, so Exaile _is_ running? Then I assume everything works fine?

[Shayne (shaynetonio)]

Sadly only the splash screen shows up and then the error noted above appears. If you're unable to replicate this issue I'll do some debugging and figure out where it's really failing

Shayne

[Shayne (shaynetonio)]

okay so the only reference to org.gnome.SettingsDaemon that I could find was in xl/xlmisc.py -- i'm guessing there might be an issue with gnome-settings-daemon not running as xfce uses xfce-mcs-manager

so either it's failing at the dbus exception handling or maybe it's failing after the statement. I'll need to run some more tests

shayne

[Johannes Sasongko (sjohannes)]

Weird, it really shouldn't just die like that. Something that might aid
your debugging is running

python -m trace -t exaile.py

It might show you where it falls over.

Make sure you kill exaile before that, though.

[Shayne (shaynetonio)]

I think exaile is failing on the playlist code:

        self.playlists_nb.connect('switch-page', self.page_changed)
        self.playlists_nb.connect('page-added', self.sync_playlists_tabbar)
        self.playlists_nb.connect('page-removed', self.sync_playlists_tabbar)
        self.playlists_nb.remove_page(0)

commenting the lines above will load the UI

i'll need to run through the playlist code to see what you guys are doing but perhaps this isn't related to gnome-settings-daemon at all....

i'll let you know what i find

Oh, I see... yeah, this is a known problem; Exaile needs GTK+ 2.10. I'm
planning to ease this requirement (to GTK+ 2.8) someday but it's not a
priority for me, so if you want to do it, feel free to take bug 159186.
