Public bug reported: Nouveau driver seems to be broken on standard installation of Ubuntu 15.10.
The only solution is to blacklist the driver in /etc/modprobe.d/blacklist.conf and then run: echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/blacklist.conf && sudo update-initramfs -u If you then reboot the computer everything works fine.
