Nvidia HW Acceleration doesn't work on certain programs
Hello Arch Friends,
This is a weird situation i have. I have a GTX 1080 Ti and I use "nvidia-dkms" drivers for it along with lib32 api's and other nvidia related api's (lib32-nvidia-utils, libva-nvidia-driver, nvidia-utils, opencl-nvidia), Mesa (mesa-utils, vulkan-mesa-layers), Vulkan (vulkan-headers, vulkan-icd-loader, vulkan-intel (I have an i7 6700K), vulkan-tools).
In principle my HW acceleration is enabled ("cat /sys/module/nvidia_drm/parameters/modeset" -> Y) and kernel parameter DRM modeset is set to 0.
Here I added some things to environment variables to "force" using the nvidia thingy in my /etc/environment. Not sure if it's a good idea, especially if I want to make use of intel integrated graphics somewhere -> https://media.discordapp.net/attachment … y=lossless
Now to the what works and doesn't work. First what works:
- ffmpeg convert video to h264 or 265 using NVENC e.g. with "ffmpeg -i input.mkv -c:v h264_nvenc -c:a copy output.mkv"
- Video Capturing screen using OBS and Nvidia NVENC encoding to H264 or H265, no problem at all.
What doesn't work:
- Steam GPU HW Acceleration. If i enable it, then the steam client will jitter when visiting store pages and especially video playback. Additionally I see my CPU usage going up significantly like 20-40% usage. Were I to disable GPU HW acceleration, then i don't have this problem.
- Cinnamon Desktop Environment (i ditched KDE). If I use just "Cinnamon" from my display manager, which uses 3D acceleration, then in just 5 to 10 minutes my screen freezes and the system becomes unresponsive to anything. After about 2 minutes my computer reboots anew as if i pressed the reset button. Currently i resorted back to "Cinnamon (Software render)" and I'll deal with this in a separate thread.
So to me it doesn't really sound like a Linux and the Nvidia CUDA reachability problem but where lies the problem? Is it the Nvidia drivers themselves (i mean I see Nvidia having a negative reputation among Linux users) and Nvidia being too lazy to make linux drivers right? Or is it, that the programs I use aren't built to support nvidia on linux properly?
What can I do?

Re: Nvidia HW Acceleration doesn't work on certain programs

That line is nonsensical and contradictory, kms isn't "HW acceleration", but a good idea, mandatory for wayland and if nvidia_drm.modeset=0 is set, nvidia_drm/parameters/modeset isn't "Y"
Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
Please post your complete system journal for the boot:
sudo journalctl -b | curl -F 'file=@-' 0x0.stPlease post your Xorg log, https://wiki.archlinux.org/title/Xorg#General
And also the outputs of "glxinfo -B" and "vulkaninfo --summary"

Re: Nvidia HW Acceleration doesn't work on certain programs
Hybrid graphics, no outputs attached to the IGP, X11 runs on the nvidia GPU
There's no indication for any problems w/ that setup.
steam client will jitter when visiting store pages and especially video playback.
vainfoYou might have to nudge the system to use the nvidia libva, "LIBVA_DRIVER_NAME=nvidia vainfo", exporting LIBVA_DRIVER_NAME might solve this problem.
steam might also try to be clever any implicitly use DRI_PRIME, but on your config, that'll probably result in using the IGP => DRI_PRIME=0
https://wiki.archlinux.org/title/PRIME# … _using_GPU
nb, if you can disable the IGP in the UEFI, you'd probably want to do that.

No, it's none of the hardware failure such as being underpowered, overheated, bad RAM or broken CPU. My HW components have been mostly the same for as many years as the intel's Skylake generation was released and i only added new RAM and a nvme SSD to it. This problem happened only 2 days ago, so since 2 days i made some changes in my Linux, that i am reverting. Plus this freeze and reboot happened in XFCE too. dmesg hasn't reported anything suspicious (i was logging it in real time) and the system resources were being used sparingly. I think i got it now (was monkeying with the USB port problem, that i blacklisted using udev rules) but we'll have to see in time.

This does absolutely never happen w/ KDE?
Indeed, I overlocked my CPU by 1 level to 4.3 GHz and my XMP RAM Profile 1 from 2133 MHz to 2400 MHz (i think. I'll need to check). System is not hot. I have a Cooler Master Evo 212 on my CPU and I use the Arctic MX-4 thermal paste, that I applied 6 months ago or so. CPU on idle is +40*C on avg.
There's a bunch of drives/partitions - is there a parallel windows installation?
Yes. I am running RAID1 on these data disk drives (Software RAID on windows and formatted in NTFS filesystem) and there's an SSD containing Windows. Don't worry, i disabled windows fast boot as i remember from previously to do that.
This does absolutely never happen w/ KDE?
I am more wondering if it'll never happen on Windows but. Me want no more crypto mining KDE.

Re: Nvidia HW Acceleration doesn't work on certain programs

Not sure about the usecase, notably since
Video Capturing screen using OBS and Nvidia NVENC encoding to H264 or H265, no problem at all.
but the idea would be to at least temporarily disable it to see whetehr the condition has any impact on the steam behavior.
I put these in "/etc/environment" now.
LIBVA_DRIVER_NAME=nvidia vainfo __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia command
that'd be wrong - proper syntax would be
LIBVA_DRIVER_NAME=nvidia
__NV_PRIME_RENDER_OFFLOAD=1
__GLX_VENDOR_LIBRARY_NAME=nvidiaand the idea would be to limit that to steam only anyway.
Is the steam problem limited to
visiting store pages and especially video playback
No problems w/ gameplay and nvidia-smi suggests steam runs on the nvidia GPU?
You have vaapi support, but I guess steam uses electron as browser and that's super picky (see the eternal https://bbs.archlinux.org/viewtopic.php … 5#p2237885 thread)
-- on the probably unrelated reboots:
Ftr "fast start" - "fast boot" generally refers to an unrelated BIOS/UEFI feature.
Make sure it's still disabled because windows occasionally re-enables it with updates and then
No, it's none of the hardware failure such as…
I'm afraid unless windows is scheduling reboots (hence the hibernation/fast-start problem) it'll come down to one of those.
I overlocked my CPU by 1 level to 4.3 GHz and my XMP RAM Profile 1 from 2133 MHz to 2400 MHz
Undo that - pick the most conservative settings possible - it's not only about heat, if you clock too fast™ the HW will loose the ability to distinguish between 0 and 1
Me want no more crypto mining KDE.
Conspiracy theory or do you mean that KDE uses up so many reources that it might as well be mining bitcoins on the side?

Re: Nvidia HW Acceleration doesn't work on certain programs
(List of To-Do's for me)
Gotcha, Seth. It'll take some time for me to test it all.
Not sure about the usecase (OBS)
Point is to offload video recording/streaming to the Intel's integrated GPU (mine is Intel® HD Graphics 530 ). Now on Windows I can do that but only for Streaming online. It couldn't keep up with recording 2560x1440 at 60 FPS and it breaks the recording, so perhaps it's not a good idea after all or I set it up wrong. On Linux i can't see the option to use the intel GPU as my Video Encoder for streaming or recording. Only FFmpeg VAAPI (or NVIDIA) - H.264 or HEVC, x264 and then there's AOM AV1 and SVT-AV1 for a reason unknown to me but my hardware does not naturally support recording using AV1.
I'll continue testing the remaining things.
regarding
__NV_PRIME_RENDER_OFFLOAD=1in my environment variables it turned out to be a bad idea. All my programs (Steam, file explorers "dolphin", "nemo") were completely black (even the minimize, maximize and close buttons) and the desktop background was black too. On XFCE the taskbar even vanished. I omitted this line from my environment variables and then set it to 0 (it's probably the default number but 0 is the GPU number corresponding to my NVidia card and 1 is the intel one)
No problems w/ gameplay and nvidia-smi suggests steam runs on the nvidia GPU?
Gameplay was not an issue for me on Linux yet. I get good FPS.

That figures.

Updates & many telemetries are disabled using community tools + group policy, so that i don't have to keep re-fighting the OS. It's not perfect but it is doing it's job mostly.
Conspiracy theory or do you mean that KDE uses up so many reources that it might as well be mining bitcoins on the side?
The latter. It was a figure of speech. Even Windows doesn't use that many resources for it's desktop environment and looking like it's "doing nothing".

See https://bbs.archlinux.org/viewtopic.php … 5#p2237885 - the best thing I can suggest from here is to "strace -f steam |& grep $HOME" and check which config file it hopefully parses for electron and play around with those parameters (or indeed disable the video acceleration)

Re: Nvidia HW Acceleration doesn't work on certain programs

Sorry seth, how do I do that?
I saw it but did i understand correctly, that the problem lies in so-to-say "the effective communication" between the nvidia drivers and the program intending to use HW acceleration? This is what i initially suspected too. It makes me wonder if AMD GPU & their drivers would not have that problem. I mean I can see how nvidia got a bad reputation in the linux community.

A computer display server protocolthe best thing I can suggest from here is to "strace -f steam |& grep $HOME" and check which config file it hopefully parses
[motherfucker_big_scorpio@Nexus ~]$ strace -f steam |& grep $HOME
[motherfucker_big_scorpio@Nexus ~]$ I took upon your consultation to undo overclocking my CPU and RAM back to their base values and specifically i can see, that the CPU "reclocks" itself automatically jumping anywhere between as low as 2 GHz and as high as 4.11 GHz, whereas on OC it would be locked at 4.3 GHz. RAM went back to 2133 MHz.
But first I want to report more results of my *other and more serious* problem, namely my system freezing in place and rebooting. Here's what I've tried and when the problem apparently has stopped occurring:
The freeze & reboot happens most prominently when watching a 1440p60 Youtube video, be it with or without HW Acceleration being enabled on LibreWolf (Firefox fork). I used this video ( https://www.youtube.com/watch?v=-vkxDQBzAGc ) as a "stress test" for that exact purpose. The problem kept re-occurring after:
- Undoing latest package installs (lightdm, cinnamon)
- performing pacman -Syu one more time
- switching from linux to linux-lts
THEN i tested it on my Windows OS and the video went through all the way.
THEN i entered my BIOS and undid the overclocking on both components and then booted into linux-lts and ran the same video from start to finish (without HW acceleration) and the video went all the way through too.
I wouldn't want to celebrate too early but you're on to something seth. I may or may not yet report the freezing & rebooting happening again AFTER undoing the overclocking.
Back to the original subject, it looks like HW acceleration on Nvidia on Linux is basically impeded on a currently technological-supportive level and us users can do not much about it, for the time being if not indefinitely?
Update:
Just tested another thing. On Steam with HW acceleration disabled i was monitoring mission center to see CPU & GPU usage in real time. Store page videos play smoothly and I see the GPU usage went up by 10% during the video playback. I'm not sure if that counts as HW Acceleration but to me it looks like the video playback is being done with the GPU doing the decoding. At the same time the CPU usage goes up by 30% during playback. I suppose the CPU hands over the hard work of decoding to the GPU and then retrieves it as the playback stream or something.

Re: Nvidia HW Acceleration doesn't work on certain programs
Check the CPU/GPU load when playing an equivalent video (codec/resolution) w/ mpv and hw decoding enabled.

It's more about electron, hw decoding generally works fine.
Something went wrong with that strace? I'm pretty sure the steam process will open *something* in your $HOME?
The plan here would be to figure whether any kind of electron config file is parsed and manipulate it in order to hopefully use the GPU for video playback.
You might btw. be interested in https://wiki.archlinux.org/title/Steam# … mory_usage ?
Sorry seth, how do I do that?
