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: ...
