[gentoo-user] Volume change overlay crashes X

[Iain Buchanan <iaindb@netspace.net.au>]

Hi all, long time no post :)  Good to see that Dale finally has aDSL
(woot).

I just upgraded to gnome 2.28, compiz 0.8.4, and various other things in
a recent large update.  I'm using ~x86.  After a few compile problems
the only noticeable problem I'm having is with the volume change overlay
(I think).

When I change the volume / mute, no nice compiz animation is shown, and
X crashes.  A udev message flashes up on the screen before X restarts:

udevd-work[1365]: error opening ATTR{/sys/class/sound/controlC0/../uevent}
 for writing: no such file or directory

I've been using the same 2.6.30-tuxonice-r5 kernel for a while - do I
need some new feature of 2.6.31?

/var/log/messages shows:

Nov  4 09:44:28 orpheus acpid: client 31528[0:0] has disconnected

which seems a bit odd.  .xsession-erros has nothing unusual:

gnome-session[31592]: WARNING: Detected that screensaver has left the bus
** (evolution:31678): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed

dmesg shows: 
compiz[31647]: segfault at 4 ip b746f2fb sp bfe11cd0 error 4 in libGLcore.so.185.18.36[b6a28000+d6f000]

I tried metacity --replace; and X still crashes (the usual volume
overlay isn't shown here either).

And get this: I tried changing the volume from the X login screen, and X
crashes!!  hmm.

Any ideas?  Thanks, as always, in advance!
