As we got a new kernel with that (4.3.2 -> 4.3.3) you could try to bisect the commit introducing the problem. With this help it is more likely nouveau developers will fix this (report a bug at freedesktop) Greetings, Tobias On 09.01.2016 11:10, Michael Hirmke wrote:
Hi *,
starting with the last snapshot from 2015 and even with this latest snapshot I've "lost" my plasma5 desktop. After starting the system I get the sddm login screen. After that and before anything else is shown the nouveau driver is throwing an error and all I get is a black screen. I can't even switch to a text console then, but I can login in using ssh, so the system is still running.
These are the messages from the log regarding the nouveau driver:

Is there anything I can do besides a bug report?
Thx and bye. Michael.
