[xubuntu-users] xfwm4 crashing and no audio output after upgrade from Xubuntu 19.04 to 19.10

[Jeffery Small]

I've had problems with the last few Xubuntu upgrades.  This one was the
worst.  The upgrade failed in the middle, taking my Nvidia graphic card
offline.  After much work to get the system back to a somewhat stable
state, with all packages upgraded, I now find that ever time I login, xfwm4
crashes.  I get a desktop and can manually launch some programs such as
undecorated and immovable  terminal windows, but there is no xfce4-panel,
even though that process is running.  I would like to know if anyone else
has experienced anything similar to this during upgrade.  If so, any
suggestions?

This is likely a bug which I reported with more details here:
https://bugzilla.xfce.org/show_bug.cgi?id=16374


Also, my sound is no longer working.  Both Alsa and PulseAudio show that
there is internal audio available and in pavucontrol, when I move the
volume slider for Line Out (plugged in) I can hear some bips through my
speaker, so they are working.  However, the internal audio channel never
makes it  to Line Out.  The same is true if I plug in headphones -- no
audio.  I do see the audio playing on HDMI/DisplayPort 2 (plugged in) which
is where one of my monitors (with no speakers) is attached to my Nvidia
K4000 GPU.  PulseAudio shows the audio output levels for that unused port.
If anyone has dealt with this problem, I would appreciate hearing about any
steps taken to resolve it.

Thanks for your help.
