SRU: PRIME Power Saving mode draws too much power

[Alberto Milone]

SRU Request:

[Impact]
Relying on the nouveau driver and on the vga switcheroo (to get around a change in systemd LP: #1777099) caused increased power consumption, and slowed down the switching process.

Furthermore, if the main X/Xwayland session was started by Gdm when the nvidia driver was loaded, the session will keep the nvidia module loaded, and prevent the system from switching off the dGPU. Also, the nouveau driver will be loaded, if nvidia is not, and this can cause problems to unsupported NVIDIA GPUs.

The solution involves the following changes:

1) Solving the problem in systemd (LP: #1777099)

2) Adding code in gpu-manager and in nvidia-prime to unload the nvidia modules, and to allow the PCI device to sleep.

3) Making a slight change to the current patch in Gdm, used to call the PRIME scripts before and after a Gdm session (so that gpu-manager gets actually called on log out)

4) Adding code in gpu-manager to kill the main X/Xwayland session on log out, if the session is preventing us from unloading the nvidia driver. A new X/Xwayland session will be created after unload the module.

5) Removing the systemd service that loads nouveau from the nvidia packages.

[Test Case]
1) Enable the -proposed repository, and install the new "ubuntu-drivers-common", nvidia drivers, nvidia-prime, and gdm3 *

2) Make sure the nvidia packages are installed, and enable performance mode (if it is already enabled, call "sudo prime-select intel" first):
sudo prime-select nvidia

3) Restart your computer and attach your /var/log/gpu-manager.log. see if the system boots correctly. If unsure, please attach your /var/log/gpu-manager.log and /var/log/Xorg.0.log

4) Select power saving mode:
sudo prime-select intel

5) Log out and log back in

6) Check if the nvidia driver is still loaded:
lsmod | grep nvidia

[Regression Potential]
Low, as hybrid graphics support does not work correctly, and the changes only affect this use case.

* Steps to test the updates:

1) Enable the bionic-proposed repositories

2) Create /etc/apt/preferences.d/proposed-updates with the following content:

Package: *
Pin: release a=bionic-proposed
Pin-Priority: 400

3) Update the list of packages:

sudo apt-get update

4) Install the packages from -proposed using the following command:

sudo apt install nvidia-driver-390/bionic-proposed gdm3/bionic-proposed ubuntu-drivers-common/bionic-proposed nvidia-prime/bionic-proposed nvidia-settings/bionic-proposed libnvidia-gl-390/bionic-proposed libnvidia-compute-390/bionic-proposed libnvidia-decode-390/bionic-proposed libnvidia-encode-390/bionic-proposed libnvidia-ifr1-390/bionic-proposed libnvidia-fbc1-390/bionic-proposed

[Alberto Milone (albertomilone)]

Here is a PPA with the current code for Bionic, available for testing:
https://launchpad.net/~albertomilone/+archive/ubuntu/hybridgraphics?field.series_filter=bionic

You will have to upgrade systemd, nvidia-prime, and ubuntu-drivers-common, call "sudo update-initramfs -u" (just in case), and reboot

[André Brait (andrebrait)]

Hey, Alberto. I have a few questions:

1. Are these changes intended to be deployed to Bionic, eventually? (I assume yes, by the names/versions you're working on, but I wanted to confirm this)

2. Would it make it not necessary to switch to nouveau at all? (I assume this is why prime-select currently has to generate another initramfs, right?)

3. Could this, along with restarting some services, make switching without a full reboot possible? Or would that still require LightDM?

Thanks!

[Alberto Milone (albertomilone)]

@André

1. Yes.

2. The new code doesn't involve using nouveau, or bbswitch, or regenerating the initramfs.

3. I don't think Gdm3 allows stopping X, calling gpu-manager, and then restarting X, as LightDm does on log out. I hope to do some work on it in the future though.

[fargoth (cantfind)]

Can we have an option to switch to the iGPU, but keep the nvidia card powered and its modules loaded so that it can be used for CUDA calculations?

[Alberto Milone (albertomilone)]

@fargoth: you can disable gpu-manager by passing the "nogpumanager" boot parameter. Wouldn't this work for you?

[Mauro Gaspari (ilvipero)]

This bug also affects me.
I am running Kubuntu 18.04 on Gigabyte AERO14, CPU:i7-7700HQ (45W TDP), GPU:Nvidia 1050Ti

I took a full system image with clonezilla, and tested Alberto Milone's PPA. System working fine after the upgrade. I tested switch+reboot around 20 times.

Test results:
No issue rebooting with or without switching GPU.
GPU Switching: Switching GPU is now much faster. Even if i use it from nvidia gui, I get the popup window asking to reboot right away.
system shutdown/reboot after I switch gpu is fast. Usual 5~10 seconds, same time it takes when I am not switching gpu.
Power usage - Nvidia mode: powertop reports around 30w idle (cpu load:2~3%, gpu ops/sec:0)
Power usage - Intel mode: powertop reports around 20w idle (cpu load:2~3%, gpu ops/sec:0) - Device stats report usage of 100% of the Nvidia 1050 in powertop, not sure if accurate.

I hope it helps.

Cheers,
Mauro

[Steve Langasek (vorlon)]

Reviewing ubuntu-drivers-common in the queue, I notice:

+ if (!match) {
+ free(match);

Surely no good can come of this call to free() and it should be omitted?

The change to start before oem-config.service seems correct but has no associated bug linked. This looks to me like it should still go through the SRU verification process because it's unrelated to the other changes. (Also, it's not 100% obvious that the change is correct: for example, why does oem-config not provide display-manager.service? Why are there no interdependencies between oem-config's systemd units and display-manager.service?)

The source package as uploaded appears to have a lot of cruft in various __pycache__ directories. This ought to be cleaned up.

I'm going to go ahead and reject based on the missing bug reference for the oem-config.service change. If you think this is wrong, feel free to ping me on IRC to discuss.

Dropping the nvidia-fallback service means that any time the nvidia module has failed to be loaded, including if the nvidia module has failed to build for any reason, the nouveau module will not be loaded in its place. This is a behavior change that potentially affects users other than those with hybrid graphics. Is that a concern? How long has the existing behavior been there, and what are the chances that users may be inadvertently relying on the current fallback behavior without knowing it?

[ubname (ubname)]

just to give some feedback, I have a optimus laptop with i7 sandibridge and nvidia GT550M, there is a led that indicates the nvidia GPU is always in use also after using the ppa to test, the laptop is indeed very hot also after I select intel and reboot and the led indicates that the nvidia GPU is in use despite selecting intel.

thanks!

[Alberto Milone (albertomilone)]

Software rendering is a better bet if DKMS fails, as nouveau can cause
problems when dealing with (partially?) supported GPUs. I introduced that
change in bionic, but then I reverted that behaviour, also because it would
cause problems to hybrid graphics.

I don't think users relying on something that is broken should hold us
back. If anything, the fallback would cause users to file bug reports
(about graphics corruption, increased power consumption, etc.) against
nvidia, where these would be really nouveau's.

[monogato (luiscastro193)]

I agree with #13

The problem is still there, switching to power saving mode doesn't save any power since the graphic card is always on anyway.

Nice catch. I think it was just debris, but it wouldn't have caused any
problem, since match could be either a valid string or NULL, and freeing a
NULL pointer results in a no-op. I have addressed this though.

I am not sure why oem-config does not provide display-manager.service, but
this change suits our needs, which I have now filed in a separate bug

My hardware: Probe URL: https://linux-hardware.org/?probe=572f1e3e6a

nvidia-fallback.service loads nouveau when I switched PRIME to Intel. I also see nouveau in `sensors` output. `systemctl disable nvidia-fallback` seems to cure the ptoblem, nouveau kernel module is not loaded any more and power cosumption _seems_ to be lower.

nvidia-fallback.service loads nouveau module even when it's blacklisted because this service starts after systemd loads kernel modules according to configs in /etc/modprobe.d/

Other PRIME fuctions work correctly except switching being much longer than it was before upgrading to bionic (18.04).

[Mikhail Novosyolov (mikhailnov)]

Can you please explain why is nvidia-fallback needed? It worked without it before.

[Mikhail Novosyolov (mikhailnov)]

Sorry, I have read above and understood why it's needed. I think prime-select can leave a dummy file somewhere and systemd service nvidia-fallback should be loaded when there is no this file written by prime-select.

[Mikhail Novosyolov (mikhailnov)]

Also, something, probably prime-select, adds nouveau.runpm=0 to GRUB_CMDLINE_LINUX_DEFAULT

$ cat `which prime-select` | grep nouveau.runpm
        boot_params['nouveau.runpm'] = '0'
                                 self._grub_path, ['nouveau.runpm', 'video=VGA'])

I don't understand why it does this, but I removed it , updated grub and everything works.

I'm still seeing cruft in _pycache_ with the latest upload of ubuntu-drivers-common.

[Claudio Desideri (happy-snizzo)]

I've done 2 tests on 2 different machines.

1) nvidia 960m, bionic-proposed: everything up to date except for ubuntu-drivers-common. Nvidia driver is working when selected with prime-select but switching to intel (prime-select intel) does not work. Nvidia is still running.

2) nvidia 970m, bionic-proposed: everything up to date. I installed ubuntu-drivers-common and nvidia-prime from Alberto's hybridgraphics ppa. Everything works correctly. Both nvidia and intel modes are working as expected. Nvidia card is now silent and cold (I have 2 separate fan for cpu/gpu) when intel is selected.

Maybe I should retry when ubuntu-drivers-common is updated in proposal?

Hope it helps.

@Serhiy Zahoriya: sorry but ubuntu-drivers-common (1:0.5.2.1) doesn't seem to be in bionic-proposed yet. No wonder things failed.

[Alberto Milone (albertomilone)]

@Steve, Brian: I have re-uploaded ubuntu-drivers-common 1:0.5.2.1, now with code to prevent shipping the __pycache__ cruft. While running debdiff against 1:0.5.2 will still mention the cruft, if you run "lintian -v ubuntu-drivers-common_0.5.2.1.dsc --pedantic", lintian won't complain about "source-contains-prebuilt-python-object" any more.

I hope we can finally get ubuntu-drivers-common into bionic-proposed now, or verification for this bug report will keep failing.

che è stata richiesta una situazione impossibile oppure, se si sta

@ubname: installing the meta-package worked here, but you can install the single packages manually:

sudo apt install libnvidia-gl-390/bionic-proposed libnvidia-compute-390/bionic-proposed libnvidia-decode-390/bionic-proposed libnvidia-encode-390/bionic-proposed libnvidia-ifr1-390/bionic-proposed libnvidia-fbc1-390/bionic-proposed

You might have to do the same for the i386 dependencies.

[AaronMa (mapengyu)]

after updated all the 5 packages below to new version, this issue seems fixed in my quick testing.

nvidia-driver-390 (390.77-0ubuntu0.18.04.1)
gdm3 (3.28.3-0ubuntu18.04.1)
ubuntu-drivers-common (1:0.5.2.1)
nvidia-prime (0.8.8.1)
nvidia-settings (390.77-0ubuntu0.18.04.1)

[Vlad Svitlichniy (vlad-svitlichniy)]

Is this fix related to nvidia-390 only or will nvidia-396 from graphics-drivers/ppa benefit from it as well?

[Alberto Milone (albertomilone)]

I don't know if they updated the 396 packages to reflect my changes in
nvidia-390.

[Aurelijus Rinkevicius (odysei)]

@Alberto I was assuming that this should also work with sddm (on Kubuntu), but apparently not out of the box. Is there already something to test there?

[Mohammads (new-mohammads)]

I was affected too, system info:
   Asus-K43SD:
    CPU: Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz
    GPU: NVIDIA Corporation GF119M [GeForce 610M] (rev a1) - [GeForce 610M/PCIe/SSE2]
    OS: 18.04 x64

Test update, works perfectly. Switching between Intel & NVIDIA happens right after logging out and getting in again. But GDM3 gone crazy(i guess it's not stable yet) and freezes after few logging in/out.

Thank you for fix

[Arthur Blair (adblair)]

I installed the packages from -proposed as per the instructions and had two issues:

1. Steam fails to launch with NVIDIA due to a "glXChooseVisual failed" error, which some cursory Googling suggests is due to a lack of 32-bit libraries—perhaps this is expected.

2. After switching from NVIDIA to Intel and logging out, the first attempt to log in again would seem to fail and just return me to the login screen. A second attempt would then succeed and take me to the desktop. This didn't happen when switching in the other direction.

[Alberto Milone (albertomilone)]

@Aurelijus: not yet. I am going to add support for lightdm and for sddm in the next update.

[Alberto Milone (albertomilone)]

@Arthur: you probably need to install the 32 bit libraries manually from -proposed. Try with the following command:
sudo apt install libnvidia-gl-390:i386/bionic-proposed

as for 2), I would need some logs such as /var/log/gpu-manager.log after reproducing the problem.

[Nikolaos Perrakis (nikperrakis)]

Hello, I saw the request for testing from the article here:

http://albertomilone.com/blog/?p=670

I 'm running Ubuntu Mate 18.04 in a laptop with i5-7300hq and 1050ti.

I didn't know of the problems mentioned but I 'd taken to switching gpus from the command line with prime-select and rebooting because of minor problems with the nvidia application. I can run some tests and upload logs if needed.

The drivers I use are:

$ apt policy nvidia-390
