Comment 1 for bug 1859526

Following up:

The xfwm4 crashing problem has to do with defining more than one independent screen in the /etc/X11/xorg.conf file. This is a problem observed by at least one other person. By commenting out the second screen in the ServerLayout section, it was possible to get the system running using the Nvidia drivers. Apparently this bug was also causing audio output to fail for unknown reasons. After the graphics problem was rectified, proper sound operation was once again also restored.

I hope this information helps others experiencing this problem. Follow this issue at:
