 Posted: Sat Feb 17, 2024 2:57 pm Post subject: [SOLVED]Nvidia GPU not used by X server with Dual GPU config |
 |
|
I have a Lenovo Legion 5 (Integrated Intel GT2 + Nvidia 1650 mobile) laptop. I want to use intel gpu for xorg but offload intense tasks to nvidia gpu.
I have followed the Hybrid_graphics wiki. But still facing issue.

I don't know why nvidia driver is not being loaded by Xorg? What am I doing wrong?

Hi,
You may check if the nvidia modules drivers are loaded :
lsmod | grep nvidia*
nvidia_drm 81920 0
nvidia_modeset 1261568 1 nvidia_drm
nvidia 55943168 10 nvidia_modeset
drm_kms_helper 192512 3 drm_display_helper,nvidia_drm,i915
drm 618496 17 drm_kms_helper,drm_display_helper,nvidia,drm_buddy,nvidia_drm,i915,ttm
video 69632 3 asus_wmi,i915,nvidia_modeset
i2c_core 110592 10 drm_kms_helper,i2c_algo_bit,at24,drm_display_helper,nvidia,i2c_smbus,i2c_i801,i915,regmap_i2c,drm

Hello,
Yes, I have followed the wiki's, you have mentioned and in the same order also.
| Quote: | | lsmod | grep nvidia* |
output:
| Code: | nvidia_uvm 1564672 0
nvidia_drm 102400 3
nvidia_modeset 1290240 1 nvidia_drm
nvidia 55484416 12 nvidia_uvm,nvidia_modeset
|
I think the modules are loaded. |

You may backup your /etc/X11/xorg.conf and run nvidia-xconfig -o /etc/X11/xorg.conf, reload Xorg then check :
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1b7 cap: 0x1, Source Output crtcs: 0 outputs: 0 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x1db cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:modesetting |

Hi,
From Xorg.log :
| Code: |
[ 22.263] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
|
What is your kernel ?
Please post the output of :
| Code: |
$ zgrep VGA_ARB /proc/config.gz
|
| Code: |
# emerge -pv xorg-server

What are you doing wrong ? Check kernel config, Xorg config and make sure the current user is in the right groups : input and video
In that setup (prime offload), the nvidia(0) card won'f show up in Xorg.0.log only the intel(0) card
Following instructions in https://wiki.gentoo.org/wiki/Intel, I removed xorg.conf and tweaked configuration files in /etc/X11/xorg.conf.d/
ls -al /etc/X11/xorg.conf.d/
total 32
drwxr-xr-x 2 root root 4096 Feb 18 11:27 .
drwxr-xr-x 5 root root 4096 Feb 18 07:27 ..
-rw-r--r-- 1 root root 179 Feb 18 08:30 20-intel.conf

-rw-r--r-- 1 root root 86 Feb 18 08:38 modesetting.conf
-rw-r--r-- 1 root root 166 May 31 2021 xkb-defaults.conf
Here is the new outout of xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 0 name:Intel

.. and the outut of nvidia-smi when I run glxgears, with the card switched off

Hi, I post my experience with PRIME offloading setup, hope will be useful for you, my Dell inspirion 7510 plus is like hybird Intel UHD and Nvidia RTX series, so my trials and errors to get this work trought many distro's, many FAQ and README end up in many CONFUSION.
For me, only right way to get prime offload "activation" is, erase all X11 (/etc/X11) and start Desktop Manager without X11 conf files, like section DEVICE, MONITOR etc...
 You can take in account for X system, at modern days, is AUTO CONFIGURE capable, and starting with empty configuration just make it's magic.
 Some required Nvidia configuration snippet is already loaded when you installing the propietary Nvidia drivers and you need to leave untouched.
Hurry up and try to look at your Xorg0.log after removing all xorg conf under /etc, and make sure you set kernel value  ibt=off (this last is essential on newer 11Th gen Intel Core) for avoid issue
My system detail:

HI,
Solved by removing xorg.conf file and running nvidia-xconfig --prime from guide.
Both cards are listed as such :
Providers: number : 2
Provider 0: id: 0x1b7 cap: 0x1, Source Output crtcs: 0 outputs: 0 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x1dd cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 1 name:Intel
Prefer sway Wayland compositor now

Please also post your :
From https://www.linuxfromscratch.org/blfs/view/stable/x/xorg-config.html :
| Quote: |
(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
This warning is displayed when a regular user starts Xorg. The library libpciaccess.so issues this warning when it tries to open /dev/vga_arbiter. If there is no more than one legacy PCI (not PCIe) graphic cards on the system, it can safely be ignored. If really necessary, the permissions of this device can be changed by adding a udev rule and adding the local user to the video group. As the root user:
| Code: |
cat > /etc/udev/rules.d/99-vga-arbiter.rules << EOF
# /etc/udev/rules.d/99-vga-arbiter.rules: Set vga_arbiter group/mode
ACTION=="add", KERNEL=="vga_arbiter", GROUP="video" MODE="0660"
EOF
|
|
You should try to create this udev rules file (and reboot) to see if this changes anything. |

Also, I have disabled Intel Management Engine by disabling the drivers required for it in the kernel config.
Can that be a reason for this not working? |

Here, it says nvidia gpu is used for rendering. And X is loaded on intel. I verified with intel_gpu_top.
intel_gpu_top shows a new process now called GPU_process. I am assuming this is offloading to nvidia gpu. Can you confirm on this, netfab?

Provider 1 which I think is nvidia gpu is showing name as modesetting instead of NVIDIA-G0

If you really want to keep your xorg configuration file, you should remove these lines :
| Code: |
Inactive "nvidia"
...
GPUDevice "intel"
|
You are saying that the nvidia card is inactive, so xorg is unloading the nvidia driver.
From your xorg log :
| Quote: |
[ 23.433] (**) |-->Inactive Device "nvidia"
[ 23.502] (II) LoadModule: "nvidia"
...
[ 23.608] (II) UnloadModule: "nvidia"
[ 23.608] (II) Unloading nvidia
|
I think you should try without it : remove this xorg configuration file and reboot. Xorg will then autodetect everything and the nvidia driver should configure itself like it should.
You should have something like this :
| Quote: |
# xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 1 name:modesetting
Provider 1: id: 0x214 cap: 0x2, Sink Output crtcs: 4 outputs: 9 associated providers: 1 name:NVIDIA-G0
|
Once you'll get that, you can test everything using glxgears (from x11-apps/mesa-progs) and nvidia-smi utilities.
| Code: |
$ nvidia-smi

From your log :
| Quote: |
[ 17220.924] (II) LoadModule: "modesetting"
[ 17220.925] (II) LoadModule: "nvidia"
[...]
[ 17220.926] (II) modeset(0): using drv /dev/dri/card0

[ 17220.968] (II) Unloading nvidia
|
The modeset driver is loaded first and is claiming both cards.
So xorg finally unloads the nvidia driver because it is not used.
On my system, where I do not have any xorg configuration file :
| Code: |
[ 19.680] (II) Applying OutputClass "nvidia" to /dev/dri/card1
[ 19.680] loading driver: nvidia
[ 19.680] (==) Matched intel as autoconfigured driver 0
[ 19.680] (==) Matched nvidia as autoconfigured driver 1
[ 19.680] (==) Matched nouveau as autoconfigured driver 2
[ 19.680] (==) Matched nv as autoconfigured driver 3
[ 19.680] (==) Matched modesetting as autoconfigured driver 4
[ 19.680] (==) Matched fbdev as autoconfigured driver 5
[ 19.680] (==) Matched vesa as autoconfigured driver 6
[...]
[ 19.680] (II) LoadModule: "nvidia"
[...]
[ 19.686] (II) LoadModule: "modesetting"
[...]
[ 19.722] (II) modeset(0): using drv /dev/dri/card0
|
You can see that the nvidia driver is loaded first, so the modeset driver can claim only the first card.
Instead of :
| Code: |
Section "Device"
Identifier "nvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:01:00.0"
EndSection
|
Try this :
| Code: |
Section "OutputClass"
Identifier "nvidia"
BusID "PCI:01:00.0"
MatchDriver "nvidia-drm"
Driver "nvidia"
Endsection
|
If that does not work, please try by removing your xorg configuration file, at least to see if xorg autodetection is working. |

Hello netfab, Thanks a lot, tried the modifcation suggested to the xorg config but that didn't work.
Finally, removed the xorg config file and everything is working fine as expected. I just can't believe it. When I first setup gentoo xorg was not working properly, hence configured the xorg config file. |

On one of my systems, all the tests I did with a configuration file to setup dual GPU with nvidia prime failed, even by following configuration examples found on wikis and/or nvidia documentation.
The only way I found to get it working is to get rid of any related xorg configuration and let xorg autodetection do its work. That's magic. |
