nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Hello everyone. I bought a new laptop for job-related needs (Lenovo Ideapad 3 Gaming 15ARH05), which sports an Optimus configuration (AMD Renoir iGPU+Nvidia GTX 1650 dGPU). It works well, until you try to play a game via PRIME render offload. I am using the default kernel+dkms drivers. No matter what i do, it has an atrocious issue with tearing. I disabled Secure Boot, added the nvidia.modeset=1 kernel parameter, i did everything as per the official Arch wiki guide, the logs show the nvidia module being loaded early as expected, xrandr --props shows PRIME sync enabled, xorg logs don't show any meaningful error. I do have to mention i have amdgpu set to early KMS via mkinitcpio. I am only using the default modesetting driver, no xf86 drivers of any kind. I had to go back to Windows temporarily since the tearing issue was affecting my job, i render 3D models and the higher ups disliked the tearing issue sad. Any help will be appreciated.

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Please post output of

$ glxinfo -B
$ prime-run glxinfo -B

xorg log and the output of xrandr --props would also be helpful .

Did you use the guided installer ? If yes, I can't help you.

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Hi Lone_Wolf, i'll reinstall Arch today since i had to wipe it due to needing the full SSD for Windows (i do renders for my job, and they usually take up a lot of my storage, and i needed the full space). If you can give me some hours i can clone my Arch installation back to my SSD and paste the output of said commands.

xorg log
https://gist.github.com/CygnusTerminal/ … e93e93b2db

I tried

cat /sys/module/nvidia_drm/parameters/modeset

and it returned "N" even though i have the kernel parameter. I also have my amdgpu module set on mkinitcpio for early loading.
Kernel is zen, with nvidia-dkms
EDIT: modeset is now enabled, but i still get tearing sad

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

glxinfo outputs look good.

[    48.143] (EE) modeset(0): Failed to make import prime FD as pixmap: 22

Is that line still present in current xorg log ?


For testing purpose install xf86-video-amdgpu and restart X , check tearing with prime-run .

Does the firmware allow changing amount of memory used by the iGPU ?

Regarding xorg:

[    12.098] (II) modeset(0): Setting screen physical size to 508 x 285
[    12.167] (EE) modeset(0): Failed to make import prime FD as pixmap: 22

Still there sad

My laptop's firmware does not allow the memory to be changed. I double checked and there aren't any options. I'll try xf86-video-amdgpu and see how i do. Thanks!
EDIT: No dice with the xf86 driver. Still get that damned tearing.

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Something I forgot to mention : please use [ code ] tags for outputs like in post #4 to make them more readable.
https://bbs.archlinux.org/help.php#bbcode for details

This is beginning to look like  a driver/firmware issue and we may have to abandon prime sybnchronization and look at other options.

Let's check some more basics first though :

Latest firmware for your laptop[1]  is FCCN16W from february 2021 . Are you running that version ?

is microcode early loading configured ?

Post dmesg and SYSTEMD_LESS=FRXMK journalctl -b output (run both as root) .
They could be very large , consider using a pastebin service

Regarding firmware, yes, i have it updated to FCCN16W
Early loading of microcode is enabled too, since i have the amd-ucode package and GRUB added it automatically and i can see in the output of [grub-mkconfig -o]
Regarding the journalctl and dmesg commands, i'll upload them as fast as i can, i am about to board a plane due to my job and i don't know when i'll be able to boot back to Arch. Thanks for all your help and sorry for the code tags, they have been added accordingly

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

I don't have sufficient knowledge to assist on the titled issue. But I myself have a new Lenovo laptop with amdgpu integrated and nvidia for dgpu. I found optimus-manager to work much better than prime.

It does look like the nvidia card is beinng initialised before the amd card.

post /etc/mkinitcpio.conf please

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Looks you're missing the modules= & binaries= part, and the modules= line is the one I'm especially interested in.

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Also, i've just added "amdgpu" to my modules list. Here are the logs you asked the other day, but with "amdgpu" added for early loading:

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Do you have TearFree for the amdgpu in the Device section in /etc/X11/xorg.conf ? ..

Section "Device"
    Identifier "amdgpu"
    Driver "amdgpu"
    Option "TearFree" "true"
    Option "DRI" "3"
    Option "VariableRefresh" "true"
#    BusID "PCI:6:0:0"
EndSection

If nvidia modeset is enabled and xrandr shows prime sync enabled, the nvidia driver should match what the device "offload to" can show in fps.

Nope, i've never enabled tearfree on any of my Optimus laptops (last one was an Intel HD 530+GTX 960m) and never had tearing issues while offloading. Tearing still exists as of right now.

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Logs indicate amdgpu is now initialised when nvidia loads, should help them to cooperate better.

Test again, if issue persists try booting with archlinux official linux kernel instead of tkg kernel .

If both kernels have the issue, try a simple WM without compositing like openbox .

Thanks i'll try booting the default kernel and report back.
EDIT: tearing is still there, sadly

5.14.9-arch2-1

Here is xorg log of default kernel while trying to play a Steam game on modesetting driver. Notice the amount of errors:

Here's one with the xf86-video-amdgpu, i still get tearing

Modeset is enabled:

I can see this line on the xorg log

[  1290.461] randr: falling back to unsynchronized pixmap sharing

Here is the log while on nvidia only mode

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

Still unclear what's causing this, but linux 5.15 is supposed to have many amd related fixes, try https://aur.archlinux.org/packages/linux-mainline/ .


Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

Thanks Lone_Wolf, hopefully upcoming kernels/nvidia drivers fix the issue!

Re: nvidia PRIME Synchronization on AMD iGPU (Ryzen 5 4600H) not working

EDIT
Well, after a test on Kubuntu, i'm... glad? To say that the tearing and stuttering/jittering issues i have on my Arch install are not present here. Everything works just as i remembered, on nvidia mode, haven't tested hybrid yet.
xorg log after playing a game:
https://gist.github.com/CygnusTerminal/ … a4b046ed71

Xorg version: 1.20.11 (12011000)

Kernel version: 5.11.0-37-generic

Nvidia driver version: 470.63.01

EDIT 2: Seems to be a regression on xorg. Today i clean-installed Kubuntu 21.10 and i am having the exact same issues as on Arch. I downgraded nvidia drivers, amd drivers, kernels and nothing helped.

That log indicates X uses nvidia as primary card and doesn't mention prime synchronization .
I think optimus-manager tries to do something similar.

No idea why newer kubuntu has the same issue as archlinux , but I think it's time to try a static conf file.

try creating /etc/X11/xorg.conf.d/10-gpu.conf with this content :

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "amd"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration"
EndSection

Section "Device"
    Identifier "amd"
    Driver "modesetting"
    BusID "PCI:5@0:0:0"
EndSection

Section "Screen"
    Identifier "amd"
    Device "amd"
EndSection

It's part guesswork so may fail.
Post xorg log from a start with it.
