*ERROR* render: timed out waiting for forcewake ack request

Question

After swapping to the IGP in Nvidia X server settings (I believe it's called), my laptop no longer boots up. I get the following message when I try:

[    5.327876] [drm:fw_domains_get [i915]] *ERROR* render: timed out waiting for forcewake ack request.

Laptop specs:

• Intel i7 6700HQ
• Nvidia 1060GTX
• 240GB SSD (Sata3) Kingston
• 8GB of Kingston DDR4

I'm not sure how to go about fixing this error, if I try to boot several times in a row I don't even get to see that message. I only get:

/dev/sda5: recovering journal
/dev/sda5: clean, 279773/5464064 files, 3236827/21840640 blocks

It just locks up after that, every time I try to boot. I tried googling the problem in the hopes of finding a solution, but I couldn't find anything relevant. (Seemingly same errors, but with old between for and forcewake)

Answer 1

Albeit late, hopefully this helps others that come across this question.

You should be able to get past your error by adding the following kernel parameter nouveau.modeset=0.

In order to do so simply:

1. Upon seeing the GRUB screen hover over "Ubuntu" and press e.

2. Add nouveau.modeset=0 to the end of the line starting with linux (this line most likely has splash and quiet near the end, simply place it right after this).

3. Press F10 and you should be in.

I know that this is a bit of a dirty workaround, but at least it allows you to get back in to your system. I will update this post if I find a cleaner alternative.
