367/370.xx + 980m w/4k screen = lock up at boot (Ubuntu 16.10)

UPDATED: Attached nvidia-bug-report to this topic.

Here’s the scenario:

Starting my laptop (Sager NP8658-S / CLEVO 650RG) with the 367.18 drivers results in a crash that can only be exited via REISUB. At startup I see it try to switch modes, but it ends up hanging with a cursor in the top left. I’ve tested this with the 4.4 and 4.6 (mainline) kernels, returning the same results. Rolling back to the 364.19 drivers restores the system to normal operation.

Os: Ubuntu 16.10 pre-alpha
Displays: Built-in = 4k 3840x2160, External HDMI = 2560x1080

3vi1, Is there any reproduction steps to hit this issue? What desktop env you are running KDE, GNOME or else? Did you observed this issue on any other system?

Is there any reproduction steps to hit this issue?

This happens consistently at boot with the 367.18 drivers installed; there are no steps needed to trigger it other than having the 367.18 drivers installed and rebooting. I’ve gone back and forth to the 364 drivers (which always work fine) 4 times, and with 367.18 the issue always occurs.

What desktop env you are running

I have KDE, GNOME, and Unity installed, but the hard crash happens right before LightDM should comes up - so I never get to the point of starting a desktop env when this issue occurs.

Did you observed this issue on any other system?

I don’t have any other systems with the same CPU/GPU, so I don’t have a good platform for comparison. I installed using the 367.18 package from the official Ubuntu graphics-drivers PPA (the same place I get the 364 drivers), which obviously must work for some people. There were no visible installation errors when installing that package via a console.

I retested this a few moments ago without the external monitor attached to verify that it has the same problem. It still fails in the same manner:

I have the same issue with Ubuntu 16.04 (kernels 4.4.0-23 to 4.6) (nvidia 361, 364 and 367.18)

I have GTX 980 and I7-5820k. I do not have the issue with driver 355.11. But then this driver does not have modesetting.

I am looking forward for any workaround that can found.

In my case it is triggered when A monitor wakes up. In particular if the monitor (not system) was suspended. I have 3 4k monitor connected to the display port (It takes longer than average to wake up these monitors) . My temporary solution is to disable screensaver and force dpms off.

I’m hitting the same issue. I have a Macbook Pro (2012 edition), and am running Ubuntu 16.04. I tried the 361, 364, and 367 drivers and all have the same issue. About 50% of the time when it boots up the screen is blank, and it seems to be correlated with this message showing up in the syslog:
“[ 15.126301] nvidia-modeset: WARNING: GPU:0: Lost display notification; continuing.”

What does that message mean, and is there a workaround? When I was running 14.04 everything worked fine, although that was with an older driver.

I just tested with the 367.27 drivers (from the Ubuntu graphics-drivers ppa), and am still seeing the same problem.

Backleveling to 364.19, as usual, gets things working again.

Something I noticed today while retesting with the latest 4.4.0-25 Ubuntu yakkety kernel. The system still hangs in the same manner, this is just an observation of a difference:

---LOG ENDS HERE when system hangs---

The amount of virtual memory used is very (4x) different between the two driver version. This laptop has 32GB of ram, but I think the 980M itself is only 8GB. I’m not sure why the newer driver would want 12GB for indirect access.

Is this by design?

I’m still unable to generate an nvidia-bug-report after the driver attempts to load. As soon as I make a remote SSH connection to the machine, that session hangs and never presents a MOTD/shell prompt.

odror and cberner, 3vi1 , Please provide nvidia bug report and repro steps of any.

odror, What laptop you using ?

Are you all exact same issue described by 3vi1 in first comment ?

My issue is exactly the same, except that I don’t even see the mouse cursor. For me, the following steps reproduce it:

  1. install Ubuntu 16.04
  2. enable Nvidia drivers via the Additional Drivers program
  3. reboot several times (blank screen happens ~30% of the time)

Also, to note, I have a Dell U3011 monitor that I use with my MacBook Pro, but the issues happens even when the external monitor is not connected.

Here’s the Dropbox link to my Nvidia log: https://www.dropbox.com/s/87mozn1yujofupd/nvidia-bug-report.log.gz?dl=0

This was captured when my computer worked fine, as I can’t log into it when the issue occurs.

One other data point. I previously had 14.04 installed and there I did not have this issue.

Let me know if there’s additional information that would be useful!

Different topic, but apparently the same problem:
https://devtalk.nvidia.com/default/topic/941096/linux/ubuntu-16-nvidia-36x-drivers-black-screen/?offset=11#4909836

Ubuntu 14 -> works
Ubuntu 16 -> not working

Is this a bug in the NVIDIA driver? If so, is there a way to make NVIDIA aware of it? It’s really annoying, I unable to use my computer for weeks now :-(

This problem persists with the 367.35 driver. Backleveling to 364.19 works fine, as usual:

Decided to test with the latest 4.7 mainline kernel today, since this laptop is Skylake. But it unfortunately seems to have the same type of issue with 367.35:

Backleveling to 364 fixes the problem as usual, but I had to also revert back to the released yakkety 4.4 kernel since the 364 drivers won’t build against the 4.7 headers.

Exact same symptoms when upgrading to the 370.23 drivers. :\

My problem was “mostly” solved when I switched to kernel 4.6.6 from the Mainline. After You switch to this kernel. Do not reboot. Shutdown and start again. If you reboot for some unknown reason the system load jumps.

Also If you disable modesetting for Nvidia it may help. The solution above works without disabling modesetting.

I have also tried Kernel 4.7. This kernel have other issues. 4.6.6 seems to be the best. You need to shutdown and start. Do not reboot. Can you report if this solves your issue.

I use Nvidia 367.35 driver. I have a 3 4k monitor system. One of them does not wake up from sleep (sometimes) which triggers the issue. It is not the only thing that triggers the issue. Again with kernel 4.6.6 It does not happen (I have been testing it for more than a week).

No joy. Mainline kernel 4.6.6 + 370.35 crashes the same way, even when starting in the way you suggested:

364.19 continues to work as a fallback.

Did you try disabling the nvidia modesetting as a kernel parameter.

It appears to make no difference; even with nomodeset, and the intel/nouveau nomodesetting for good measure, the nvidia-modeset executes and hangs at startup:

Tried 370 again a few times with nvidia.modeset=0 added to boot options… same bag of errors:
