NVidia M1000M GPU problem on Ubuntu 16.04

[i2000s2]

I got a whole bunch of errors in the TTY1 mode when I was restarting lightdm and the system stuck there. I rebooted with a hot power off. Now

qxd@qxd-QC5-Ubuntu:~$ lsmod | grep nvidia
nvidia_uvm            696320  0
nvidia_modeset        745472  3
nvidia              10076160  60 nvidia_modeset,nvidia_uvm
drm                   360448  8 i915_bpo,drm_kms_helper,nvidia

A second monitor is connected... I will check if the tearing/flickering issue is gone when it sleeps and wakes...

We are solving it!

[i2000s2]

So, after idle sleeping, the screen can come back. The only problem is that when it wakes up, the external screen can only mirrors the primary screen and there is no login window pops up. I have to go to the TTY again to restart the lightdm service.

Once I login, there was a crash report prompt shown up and asked me if I wanted to report this issue. I think this is a bug of the kernel and the driver.

Anyway, I think you have helped me found the culprit and fixed the most annoying problem! I will try out some other newer kernels for better PM support.

BTW, how can I confirm if the hybrid graphics is using Optimus? I heard this system should be able to switching inbetween NVidia driver and Intel driver automatically and is energy efficient.

i2000s2; Welp;

Hybrid graphics is a horse of of a different color .
Is the integrated GPU enabled in bios ? I see no indication of another graphics set in the log file .With hybrid graphics in use .. that xorg.conf file is required !
Enabling the on-die graphics in bios, Does the system see both sets ?

lspci -k | grep -EA2 'VGA|3D'

does the kernel see the hardware ?

sudo lshw -C display

ain't nothing but a thing

[i2000s2]

Yes, there are two graphic cards, one is the integrated Intel 530 card, the other one is the NVidia Quadro M1000M. So the code seems echoing this fact:

qxd@qxd-QC5-Ubuntu:~$ lspci -k | grep -EA2 'VGA|3D'

And surprisingly, I also got the Xorg.conf file:

Aha, I also got the nvidia-PRIME work to configure the GPUs. See the attached nvidia-settings window:

Hmmm, a problem found after this installation as half-expected:
Matlab 2016a crashes with the NVidia-361 driver!

The matlab situation, looks like ya need to be talking to the authors.

we do what we can

with what we have to work with

[i2000s2]

Thank you, Bashing-om! You are very helpful and professional! I wouldn't notice the small error in the driver installation script, that is the biggest lesson I have learned today.

I have basically solved the matlab crashing problem by turning off the opengl support, which is not decent but works. I guess the Optimus technique is working as long as I can choosing GPU drivers freely. I will mark this thread as SOLVED right away! Will be sharing my experience of installing the driver on my machine type later.

Have a good one!

[i2000s2]

I just found a patch to the nvidia 361.19 to solve the compatibility issue with kernel 4.6: https://devtalk.nvidia.com/default/t...c3-included-/2

Now need to figure out how to apply this patch... It could be fixed in the next driver release I guess.

[Bashing-om]

i2000s2; Hold on.

maybe exercise care here as the version installed is " Preparing to unpack .../nvidia-361_361.42-0ubuntu2_amd64.deb ...'
And the patch applies to older versions " 364.1[2,5] .

Now if ya must .. might try the 364 version driver . You know how now to revert back to 361 if 364 does not work .

Hey It is a thought

but I was wrong, once
