--- Comment #25 from Brandon Bertelsen <brandon at bertelsen.ca> ---
I suffered from the same bug. I was able to fix it with some help from users on
IRC as well as the files presented here. Figured I'd provide explicit
instructions for others. (I'm using Ubuntu 13.10). 

1. First make sure you have NV6 firmware

$dmesg | grep nouveau | grep Chipset

You should see something that looks like: 

[    2.318701] nouveau  [  DEVICE][0000:01:00.0] Chipset: GK106 (NVE6)

2. Download and move the files from Jordan Bass (thanks!) in comment 19

sudo mkdir /lib/firmware/nouveau
sudo /path/to/extractedfiles/* /lib/firmware/nouveau

3. Update initramfs

sudo update-initramfs -c -k <YOUR_KERNEL>

4. Update GRUB

sudo nano /etc/default/grub

Add nouveau.config=NvGrUseFW=1 to GRUB_CMDLINE_LINUX_DEFAULT so that it looks
like: 

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.config=NvGrUseFW=1"

5. Update grub

sudo update-grub

6. Restart and verify

sudo shutdown -r now

On restart: 

$dmesg | grep external

[    2.484773] nouveau  [  PGRAPH][0000:01:00.0] using external firmware

If you see PGRAPH using external firmware, you're done.
