Suspend fails, GPU has fallen off the bus (Nvidia)
My problem is that my laptop does not wake from suspend mode. It shows me only a black screen with one sentence
[1300.001615] NVRM: Xid (PCI:0000:07:00):79, GPU has fallen off the bus.
My OS is Ubuntu 16.04 LTS. I used to work with Ubuntu 15.10 and everything was fine.
Nvidia GeForce 740M
lspci | grep -E "VGA|3D"
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
07:00.0 3D controller: **NVIDIA Corporation GK208M [GeForce GT 740M]** (rev a1)
I have to push the power button for 10 seconds to shut it down and then turn it on.
In software & updates I chose to use Nvidia binary driver - version 384.69 from nvidia 384 (open source) and this driver is listed on nvidia's site as the latest recommended driver.
The NVIDIA GeForce GT 740M supports NVIDIA Optimus technology (switchable graphics technology). Is this technology the cause of the issue?
If you have any questions, please ask me, I will answer with pleasure.
Thanks in advance ;)
As was said in nvidia backlight brightness problem, it seems your solution would lie in upgrading to at least 381 as there was a critical bug in the previous versions regarding suspending.
Wish I could do more, but I think you will be solved with that.
