[SOLVED] primusrun crashes with "undefined symbol"

kpj · 2021-11-30 20:18:12

# original title: primusrun crashes with "undefined symbol: glXCreateContextWithConfigS"

When I try running a graphical application using primusrun, I get the following error:

$ primusrun glxgears_fbconfig
glxgears_fbconfig: symbol lookup error: glxgears_fbconfig: undefined symbol: glXCreateContextWithConfigSGIX

The same happens with pvkrun.

I have the following versions installed:

local/lib32-primus 20151110-4
    Faster OpenGL offloading for Bumblebee (32-bit)
local/lib32-primus_vk 1.6.1-1
    Nvidia Vulkan offloading for Bumblebee

    Tool for configuring the NVIDIA graphics driver
local/nvidia-utils 495.44-6
    NVIDIA drivers utilities
local/primus_vk 1.6.1-1
    Nvidia Vulkan offloading for Bumblebee

When I search for this error in the context of primusrun, I do not find anything.

Do you have any idea what could be going wrong or how to even debug this in more detail?

Check the xorg configs bumblebee uses in /etc/bumblebee/xorg.conf.nvidia and uncomment the BusID (and double check it's correct in lspci or so) there seems to have been a change in the way xorg applies device sections that now requires an explicit identification directive.

Other than that primus-run has not been in development for quite some time and afaik also uses quite a specific injection method, does normal optirun work?

kpj · 2021-11-30 21:59:03

The line with "BusID "PCI:01:00:0"' is already uncommented in /etc/bumblebee/xorg.conf.nvidia and it's indeed the right one:

$ lspci -v -s 01:00.0
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev ff) (prog-if ff)
	!!! Unknown header type 7f
	Kernel modules: nouveau, nvidia_drm, nvidia

Is it currently recommened to use optirun or primusrun? Because of askubuntu I assumed primusrun was favored (how does optirun work with Vulkan?).

"optirun glxgears_fbconfig' does indeed work without crashing.

Your GPU isn't supported by 495xx
https://aur.archlinux.org/packages/nvidia-470xx-dkms/
https://aur.archlinux.org/packages/nvidia-470xx-utils/

kpj · 2021-12-01 09:53:58

Interesting, I hadn't considered that. Can I see somewhere which driver versions are supported by my GPU?

I have now installed the packages nvidia-470xx-utils nvidia-470xx-dkms nvidia-470xx-settings lib32-nvidia-470xx-utils.

Unfortunately, executing "primusrun glxgears_fbconfig" results in the same error as before

V1del · 2021-12-01 09:59:20

GM107 is Maxwell, should still be supported by the current nvidia 495 package. I really think primusrun is just broken, but not entirely sure which of the updated components (could be xorg or mesa or so I'd guess) is to blame, if you can take the slight power drawing hit (...which I've wanted to test on my 950M for a while now, didn't get around to that yet), using nvidia-prime instead is likely more fruitful

kpj · 2021-12-01 10:10:10

Okay, I upgraded to the latest nvidia drivers again and also installed nvidia-prime.

When I try using prime-run I get this new error:

$ prime-run glxgears_fbconfig
GLX 1.3 is supported.
GLX_SGIX_fbconfig is supported.

The following fbconfigs meet the requirements.  The first one will be used.
[..]
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  1480
  Current serial number in output stream:  1481

Not sure what that is supposed to mean.

For properly using nvidia-prime you'd have to remove bumblebee, maybe also post a xorg log.

Oh right! I now uninstalled the packages bumblebee bbswitch lib32-primus lib32-primus_vk primus primus_vk and "prime-run glxgears_fbconfig" actually runs.

Is there any way of checking whether the Nvidia GPU is actually used though?
When I run games with prime-run and MangoHud, it shows that only my Intel GPU is used and has very low FPS.

nvidia-smi should show more than just xorg as the used processes. Also in general you might want to remove xf86-video-intel as xorg's built-in modesetting driver is better tested with this method and xf86-video-intel has in general a few buggy behaviours

kpj · 2021-12-01 11:39:42

I now removed the xf86-video-intel package.

According to nvidia-smi this seems to work. I first run "prime-run glxgears_fbconfig" and then get this:

In fact, nvidia-smi also lists the game I start in its processes section while MangoHud says it's using the Intel GPU and it has the same FPS as when not using prime-run.
Any idea why that could be happening?

seth · 2021-12-01 11:48:20

When I run games with prime-run and MangoHud, it shows that only my Intel GPU is used and has very low FPS.

How exactly?

Sicne mangohud seems to be a wrapper around the binary and prime-run is too, order and export level will matter.
Look at https://github.com/archlinux/svntogit-p … /prime-run and just export the variables to your current shell, then "mangohud $THEGAME" from that shell.

Edit: btw, sorry because of wrong driver support statement :\

Good question! Everything seems a bit confusing right now, so I will try to be as clear as possible.
All following investigations are with $DXVK_HUD=1 and $MANGOHUD_CONFIG=full.

When I just run "glxgears_fbconfig" I obviously only see the gears.
When I run "mangohud glxgears_fbconfig", MangoHud displays (the literal text) Geforce GTX 960M but "nvidia-smi" only lists the Xorg process.
When I run "mangohud prime-run glxgears_fbconfig", MangoHud also displays Geforce GTX 960M and "nvidia-smi" also lists the glxgears_fbconfig process.

Now consider the Steam game Trackmania Nations Forever.

First, I will launch it from the commandline.
When I run "wine TmForever.exe" the game starts and no HUD is shown.
When I run "mangohud wine TmForever.exe" also no hub is shown. This I do not understand.
When I run "prime-run mangohud wine TmForever.exe" no hub is shown and the graphics are messed up (everything is black and white).

Second, I launch Trackmania from within Steam and modify the LAUNCH OPTIONS in the general properties menu of that game.
When I use "%command%" there is a HUD on the top left which does now say "Geforce GTX 960M" instead of Intel as before... And the FPS are around 200 instead of 22 as before...
So things suddenly things work although I did not even use prime-run?

In preparation for this, I unset the environment variable VK_ICD_FILENAMES="/usr/share/vulkan/icd.d/nv_vulkan_wrapper.json:/usr/share/vulkan/icd.d/intel_icd.x86_64.json:/usr/share/vulkan/icd.d/intel_icd.i686.json" which I needed before for things to run...
This seems to have been the magical change.

While it is nice that things somehow seem to work, I am still deeply confused: why is my Nvidia GPU being used without me enabling it? Why does MangoHud display my Nvidia GPU while nvidia-smi does not list it in the glxgears example? Where does the Steam HUD for Trackmania come from? When I launch CS: Source I do not get it.

For proton/wine/dxvk or in general Vulkan titles, if you didn't installed vulkan icd files for your integrated chipset, the available icd files you probably installed just for nvidia or the one with greater priority is used.

koko@Gozer# pacman -Ql nvidia-utils|grep icd
nvidia-utils /usr/share/vulkan/icd.d/
nvidia-utils /usr/share/vulkan/icd.d/nvidia_icd.json

Why does MangoHud display my Nvidia GPU while nvidia-smi does not list it in the glxgears example?

This could be a mangohud related issue.

Where does the Steam HUD for Trackmania come from? When I launch CS: Source I do not get it.

No idea about that, i don't even know how this HUD is made

Afaik dxvk has on it's own code that will prefer a dedicated GPU without the lib-bender prime-run needs to do, but it shouldn't be harmful to combine the two.

So DXVK can be ran without prime-run and will automatically use dedicated GPUs, everything else should have prime-run to ensure the proper injections happen.

Didn't know about that!

but it shouldn't be harmful to combine the two.

Indeed:

Makes sense! I did notice that native Linux games need to be run with "prime-run %command%" while Proton games need nothing to be run on the Nvidia GPU (just as @V1del suggested).

No idea about that, i don't even know how this HUD is made

Turns out this HUD is another consequence of DXVK. Linux games (like CS: Source) don't have it while Proton games do.
When I run the Proton game with "DXVK_HUD= %command%" the HUD disappears.

Everything seems to work (for now...). I'll try to enjoy it until a random kernel/driver update breaks everything again :-D
Thank you all so much for your help!
