Public bug reported:
Yesterday, I upgraded from Ubuntu 12.04 via 14.04 to 16.04 (LTS version
in each case). From 14.04 on, I was unable to graphically log in. A few
seconds after the login (varying between 1 and 10 s), the screen changed
to a pattern with dense white stripes on the violet/red background, and
X froze (no reaction to mouse or keyboard). The latest messages in
"/var/log/syslog" each time showed varying "nouveau E" problems, e.g.
"unrecognized interupt", "PFIFO", or "PBUS" problems such as e.g.:
"nouveau E[ PBUS][0000:00:0d.0] MMIO write of 0x01f70001 FAULT at
0x00b010" (values and addresses varying).
An internet search revealed that the problem is well known. It affects
many NVidia graphic cards with the "nouveau" driver. Usually, the freeze
happens when e.g. "firefox" is started (which happens in my context
automatically after a graphical login). Most reports recommend to switch
from "nouveau" to the proprietary NVidia driver. However, there seem to
be problems with that driver for recent Ubuntu versions. I my case, the
NVidia driver could not be started (I did not investigate why). One
report suggested the boot parameter "nouveau.config=NvMSI=0" which in my
case made the graphical login successful again.
Today, I wanted to report the bug with "ubuntu-bug". However, during the
collection of the system information, the error happened again (despite the
"nouveau.config" boot parameter).
Syslog gives:
