Clicking sound menu crashes unity-panel-service

[zerwas]

When i click on the sound menu indicator, every other indicator but the messaging menu disappears. Scrolling the mouse wheel on the sound menu indicator icon to change the volume is still possible. I can't tell when this bug started to appear.

See the attached video clip for what happens. If there is any additinal information i can provide i would glad to help you.

This is the output when i start indicator-sound-service in the terminal. "Get state - 2" is what appears when i click on the sound menu.

[zerwas (zerwas)]

Using strace on /usr/lib/indicator-sound/indicator-sound-service, log file is attached.

[zerwas (zerwas)]

dmesg shows that unity-panel-service crashes when i click the sound menu:
[ 7908.903643] unity-panel-ser[13550]: segfault at 1c ip 00007f220e255235 sp 00007fff4460c1e0 error 4 in libgdk-3.so.0.200.0[7f220e226000+77000]

So i did a backtrace which is attached to this comment.

Backtrace for unity-panel-service was missing symbols, correct backtrace is attached.

This bug only happens when Option "Composite" in xorg.conf is set to "Disable". With compositing enabled, everything works fine.

I installed 12.04 alpha 1 on a newly partitioned disk. The behaviour was exactly the same: mousing over the sound applet icon caused the error reported above. zerwas' Composite xorg.conf edit seems to be all that was needed to make the problem go away.

My xorg.conf was generated by nvidia-settings for two monitors of different resolutions on the same card using 'X screen + Xinerama', if that helps.

[Bilal Akhtar (bilalakhtar)]

From what I'm concluding after reading Sean and zerwas' comments, this appears to be more of a nvidia driver issue rather than one about indicator-sound. I might be wrong though.

[zerwas (zerwas)]

Bilal Akhtar, not only nvidia users are affected. ATI Radeon HD 3200 here.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Conor Curran (cjcurran)]

According to the unity guys composite should not be disabled. Bug belongs to nvideodriver, the xorg conf it generates should not disable composite.

[Marciano (pensalo)]

I have the same problem and I have and ATI graphics card. not sure which one exactly

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
