Comment 6 for bug 1716456

I purged the xorg-edgers ppa in order to eliminate unstable libraries ... yet the crash continues to occur.

I could not get an earlier version to downgrade xserver-xorg-video-nouveau and doing some tests.

The situation gets very unstable when I allocate 1 application in each workarea ... when it arrives in 4 or 5 workareas the session falls and ubuntu returns to the login interface.
