Volume Control plugin can't be added to xfce4-panel

[picpak]

Binary package hint: xfce4-mixer

Hello,

With Xubuntu 6.10 and the latest updates, I cannot add the Volume Control plugin to my
panel.

I right click the panel, click add new item, and add the Volume Control plugin.

A little black line appears on the panel, then disappears. No plugin.

When I run xfce4-panel through the terminal and then try to add the plugin,
this is what I get:

kim@komputer:~$ xfce4-panel
The program 'xfce4-mixer-plugin' received an X Window System error.

Can anyone help me?

[Gauvain Pocentek (gpocentek)]

I can't reproduce this here. On which arch do you run Xubuntu?

[picpak (k-belding)]

Just i386, with the generic kernel. Thanks for your help!

[picpak (k-belding)]

Do you, by any chance, have a file set to load xscreensaver in Settings>Autostarted Applications? I had one that looked like this:

#!/bin/sh

sleep 1 && conky &
xscreensaver &
xmodmap ~/.Xmodmap &
xbindkeys &
adesklets --xfce4 &
mpc update | mpc ls | mpc add | mpc shuffle

I removed the line "xscreensaver &", and it worked perfectly. Hope this helps!

[picpak (k-belding)]

After some more checking, it turns out it's not xscreensaver. I had simply assumed it because it had loaded after closing it. The problem, strangely enough, lies in xbindkeys.

Just configure your keys through Xfce's keyboard settings, and remove xbindkeys from your list of startup programs. It's been working for me ever since.

[Hellodilou (elodie-cecillon)]

Hello,

I have this bug too, on a Xubuntu 7.04. I don't have xbindkeys installed, so this is not the real cause of the problem, at least for me.

Dragging the mixer applet to the panel works, but I have to do it every time I start an X session, which is kind of bothering.

Here's a (pruned) list of what's running on my computer. Do you spot anything that might cause xfce4-mixer to crash, just like xbindkeys did for the previous reporter?

[Expired for xfce4-mixer (Ubuntu) because there has been no activity for 60 days.]

[Lionel Le Folgoc (mrpouit)]

I reproduced this bug on gutsy some time ago, but now it works out of the box (doesn't mean there is no bug).

[Dax Solomon Umaming (knightlust)]

Thank you for reporting this bug and help make Ubuntu better. I confirm and reproduce this bug. There seems to be different workarounds for different users. Here's my workaround to get my Volume Control on the panel: I re-launch xfce4-panel, then add it as usual. However, the volume control's missing after reboot and I have to repeat the procedure. I'm not really sure what other information you need, but please advise.
I'm changing Importance to Low since there's an existing workaround.
Thanks

[Brian Avery (briansvgs)]

I am running xubuntu gutsy, and the volume control still fails to appear on the panel.
After installing gutsy on my vostro 1400 laptop, I added the volume control plugin to xfce4-panel.
Then I modified /etc/modprobe.d/alsa-
base, adding the line "options snd_hda_intel model=3stack" in order to
get my speakers working, and rebooted. Upon logging back into xfce, the
volume control has dissapeared plugin has dissapeared. When I run xfce-
panel through the terminal, the output is as follows:

The program 'xfce4-mixer-plugin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
 (Details: serial 201 error_code 11 request_code 53 minor_code 0)
 (Note to programmers: normally, X errors are reported asynchronously;
  that is, you will receive the error a while after causing it.
  To debug your program, run it with the --sync command line
  option to change this behavior. You can then get a meaningful
  backtrace from your debugger if you break on the gdk_x_error() function.)

Trying to add the plugin back onto my xfce panel doesn't work either, and neither does dragging the plugin onto the panel. Also, after the mixer crashed, the volume control multimedia buttons on my laptop stopped working.

[Steve Dodd (anarchetic)]

I'm seeing this on Gutsy final. It seems to be dependent on the theme - (Applications -> settings -> user interface -> theme tab.) For example, "Human" causes the crash (BadAlloc, rather than the BadAccess mentioned in one report above), "MurrinaStormCloud" is OK.

[garybrlow (garybrlow)]

Confirming this as well. Am on Xubuntu Gutsy Upgrade with compiz-fusion. Every Xubuntu Distro I have used before since Dapper have had this problem at some point. I was hoping this recurring problem would be solved already in Gutsy but its still here. :P

Killing/restarting xfce4-panel and adding the control worked a few times but now it refuses to be added again. Dragging the control to the panel seems to work as of the moment.

[Steve Dodd (anarchetic)]

Sounds like there might be multiple bugs here, some of the attached duplicates don't sound the same either.

[picpak (k-belding)]

I added the plugin after my Gutsy upgrade and it's been there ever since. Great! :)

[Helmut Duregger (helmutduregger)]

I also have the mixer plugin disappear.

The drag-n-drop workaround seems to work fine.

There is also a bug entry at
http://bugzilla.xfce.org/show_bug.cgi?id=2971
for this bug.

[Jérôme Guelfucci (jerome-guelfucci-deactivatedaccount)]

I'm closing the tasks other than xfce4-mixer becauses they seem to be irrelevant.

[runokiab (launchpad-5-baikonur)]

I can confirm this bug.

The drag-n-drop workaround works depending on your theme. That means, if you have "MurrinaStormCloud" as your current theme it works, but if you use "Human" instead it doesn't. So you need to set your theme to "MurrinaStormCloud" and drag the mixer-plugin to the panel instead of clicking on "Add".
See http://ubuntuforums.org/showthread.php?t=375118

[David Dent (thewinch-deactivatedaccount)]

In my case the offending panel items work fine unless I use a horizontally orientated panel (top or bottom of screen) with one of the following three themes.

Human
Outdoors
Silicone
These three themes are the only ones that use the ubuntulooks engine which appears to come from package gtk2-engines-ubuntulooks.

If the panel is vertically oriented (left or right of screen) then the panel items work with all themes.

If the panel is started under a different theme then switched to one of the three above themes the panel items will continue to work.

[Jimmy Wu (jimmywu013+launchpad)]

I get the same error message as the OP, but it's with xfce4-xkb-plugin. Volume Control Works perfectly.

[tlvince (tlvince)]

Confirmed here (7.10), using Human Theme triggers the bug. Switching to another theme, adding the mixer panel and then switching back to Human has worked for me

[Jarno Suni (jarnos)]

I use the volume control applet provided by xfce4-xfapplet-plugin now that the plugin in xfce4-mixer does not work (in Gutsy). You can install even many of these, e.g. one for capture. (Mute did not work for capture like unchecking activate in qamix, though.) Changing themes might have something to do with the failure in adding xfce4-mixer's volume control to panel.

[quinn_noel (quinn-noel)]

I may have found a work around. I am running Xubuntu 7.1 and using the Mplayer plugin in Mozilla. As you described there is no volume control, no link , ikon , or information link. While clicking around in the applications menu I started XMMS and discovered that although there is no input showing in the display the volume control built into its GUI actually works. I guess this means that XMMS has set itself as the default player but that Mozilla doesn't look there before starting the Mplayer plugin. I hope this helps.

[quinn_noel (quinn-noel)]

Just an addition to that , since then I have discovered that xgine is the default.

[Jarno Suni (jarnos)]

Another work around (that I tried to explain earlier): You can add a respective XfApplet item to the panel after installing xfce4-xfapplet-plugin.

[quinn_noel (quinn-noel)]

Thankyou I will give it a look.

I use Xubuntu Gutsy 7.10 64-bit (amd64)
I cannot use xfce4-mixer as an Item in the panel.
I think that it was working just after clean install
but it stopped working later and now i can`t use xfce4-mixer in panel.

So, On 7.10 xfce4-mixer does not work on panel. (only if i start it manually, apart from panel)

[quinn_noel (quinn-noel)]

Thankyou, I'll have to go back to the site and read it again because at this stage I cant start it manually or any other way, although I can work around that using the volume control in XMMS.

same issue here. Just installed xubuntu-desktop and am unable to add mixer applet. Black line appears then disappears. I tried changing themes with no effect.

[Radomir Dopieralski (ubuntu-sheep)]

I found out that I can't add a volume plugin to the panel in Hardy unless I first remove the keybindings for the media keys in the keyboard settings. Removing them fixes it (the plugin handles them, so there is no loss of functionality).

[Jarno Suni (jarnos)]

I can add the volume control in Gutsy after I remove keybindings for the media keys in the keyboard settings.

[markor (markoresko)]

Only way to make Volume Control to the panel is
drag`n`drop method from add items window to the panel.
it seems that it temporarely make it usable.

Could someone tell here what are the keybindings for the media keys in the keyboard settings? (I have forgotten them, since I removed them to be able to add the volume control.)

BTW I tried to install latest trunk from svn and here's what I got:

xubuntu hardy: add volume-applet over gui does not work, nothing on panel.
simply dragging from panel-items-list with mouse and dropping it onto panel did help.
thanks

[Magnus Hedemark (viridari)]

Bug definitely still exists in Hardy (on amd64 arch in this case).

Workaround given in https://bugs.launchpad.net/xfce4-mixer/+bug/90261/comments/35 worked for me. I set up a custom key mapping, same as default key mapping but minus the media keys, and it just started working.

[Dax Solomon Umaming (knightlust)]

Still an issue on Intrepid. Doesn't work even with a different theme - tried 8 themes.

[Charlie Kravetz (cjkgeek)]

I ran into this after installing Xubuntu 8.04.1, installing all updates, then upgrading to xubuntu 8.10 using update-manager -d -c . There was no volume control on the panel in Hardy 8.04, although it could be added and removed. In Intrepid, it can not be added.

[OrangeCrate (orangecrate-gmail-deactivatedaccount)]

Volume control problem with Xubuntu 8.10 RC confirmed. Installation method different, however. I added Xubuntu desktop over a full installation of Ubuntu 8.10 RC.

[maharaja (maharaja84)]

Same here. I can't add the Volume Control to the panel when using Xfce.

[RomanIvanov (ivanov-jr)]

I have the same problem in 8.04 and in now in 8.10.
Thanks to "markor wrote on 2008-03-24: (permalink)" please see comment above - this work like a charm for me.
But is it only workaround.

[Ulf Adams (ulf-ofahrt)]

I also encounter this bug, having just upgraded from 8.04 to 8.10. It worked before, but now I can't add the volume control to the panel any more. After clicking furiously for a while, it was added to the panel once, but gone again after the next reboot.

[Willi (strangeq)]

Same here. The problem popped up after the upgrade to 8.10.

[James M. Cooper (jmichc)]

This bug really has been around, apparently.

I am experiencing the same problem in Xubuntu Intrepid, but in my case, it did not show up until after the upgrade to 4.4.3 an evening or so ago.

The drag and drop method is functioning as a temporary workaround.

[Cody A.W. Somerville (cody-somerville)]

This bug has been fixed in Xubuntu 9.04 Beta (codename: Jaunty) thanks to the rewrite of the panel applet in Xfce 4.6.

[billynoah (billynoah)]

i recently upgraded to xfce 4.8 running ubuntu 10.04 and encountered this issue. i can not add mixer to panel by adding items or by dragging it on the panel. however, a simple workaround which worked for me was to create a launcher item in the panel which runs /usr/bin/xfce4-mixer.

[Lionel Le Folgoc (mrpouit)]

10.04 doesn't ship Xfce 4.8. If you've compiled it yourself, or installed from a third-party repository, make sure you've upgraded panel plugins as well, otherwise they won't work.
