Public bug reported:
I had nouveau related problems in Ubuntu 16.04: quite often, the display
screen was replaced by an irregular black and white pattern and the
system no longer reacted to the mouse or the keyboard.
Since the Ubuntu 18.04 upgrade, the problem shows itself slightly
differently.
I have lived for more than 1 year with the problem (as told earlier, the
freeze happens nowadays only occasionally) and, thus, I do not need a
backport but can wait for 18.04 to be released. Thank you again!

Using a different drive, I could successfully burn the daily Ubuntu Live
CD. I was not able to reproduce the freeze with the corresponding
installation.
Thank you for your support.

I tried, but the resulting DVD does not boot:

Responses to your previous questions:
1) It may take a bit of time before I can make the tests with the current
Ubuntu version. And, I fear that such tests might not be reliable: after the
temporary use of the NVidia driver I could use the "nouveau" driver for some

In comment #6 I had reported that "apport-collect 1649566" reproduces
the freeze.
I was now able to successfully transfer the data by calling "apport-
collect" outside the X system. Because, it did not run under X, it might
not contail all information you would like. In this case, let me know
how
Calling "apport-collect 1649566" reproducible causes the crash reported in this

Is there a different way to provide the information you need?

For me, the situation has significantly improved with the latest Ubuntu
16.04: for "normal" operation, I no longer need "nouveau.config=NvMSI=0"
