LXDE Forums

I'm on Ubuntu 9.04 and since installing LXDE, pulseaudio stopped working, or rather the module 'module-x11-xsmp' stopped working. pactl load-module module-x11-xsmp gives 'Module initialization failed'.

Some more info;

From syslog:
Sep 12 05:19:42 mediamaskinen pulseaudio[4867]: x11wrap.c: XOpenDisplay() failed
Sep 12 05:19:42 mediamaskinen pulseaudio[4867]: module.c: Failed to load module "module-x11-xsmp" (argument: ""): initialization failed.

Pulseaudio is otherwise correctly loaded at boot from original init.d script and sound does work, but it crashes after playing 1-2 minutes. Sound do work under Xfce sessions and if switching to alsa in Smplayer it doesn't lag or crash in Lxde. Trying manually with pulseaudio -D and other such commands gives the same result, x11-xsmp won't load and sound crashes. I've googled this to my eyes bled and found this:

"lxsession-lite: lxsession does not provides X session management"

And echo $SESSION_MANAGER gives a blank line. I'm running latest lxsession revision 1997 from svn and before that lxsession-lite 0.3.6.2 from Ubuntu repos with the same problem.

What more can I try? Or is it a bug? Can I give you more info?

And now I have the latest lxsession and lxde-common from svn, revision 2003.
echo $SESSION_MANAGER
Still gives a blank line as ouput.

Might have found the problem here: http://www.pulseaudio.org/wiki/KnownIncompatibilities

Some recent libc versions have a locking problem in the dynamic module loader, which will cause PulseAudio to freeze randomly. This has been fixed in Fedora glibc 2.6.90-14

I run glib 2.6.4 from Ubuntu repos so seems I better have to wait. I think glib was recently updated and broke.

glibc is NOT the problem! I've just made a mixed installation of Xfce-session-manager and openbox and pulseaudio works and module-x11-xsmp now loads fine!

So somewhere lxsession isn't to friendly with x11-xsmp.
