[BUG] VR Compositor displays SteamVR on Laptop Screen

[shaunblyde]

Describe the bug
I am running an all-AMD laptop (Asus G513QY) and have tried many troubleshooting suggestions, but cannot get SteamVR to display on my Valve Index, VRCompositor always shows on my laptop display instead. There is no issue with movement of the headset and controllers as this can be demonstrated as functional within the display of VRCompositor.

I am currently using DRI_PRIME=1 VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json %command% as Launch Options within Steam, and running X11.

It works fine on Windows, so there is no hardware issue, they USB-C port I am using (to DisplayPort adapter) is directly connected to the dGPU.

I suspect SteamVR is not loading using the dGPU (despite my best efforts with Launch Options) as there is a line in the logs (see below) referencing the AMD RADV RENOIR, which I believe is the iGPU. My understanding is that this would also explain the Failed to acquire xlib display error.

SteamVR also wants to select 90Hz as the operating frequency, and I would like it to run at 144Hz. I cannot currently change this, but perhaps it will become possible once the display issue is resolved.

Thank you for the assistance.

To Reproduce
Steps to reproduce the behavior:

1. Create '/etc/X11/xorg.conf.d/10-steamvr.conf' with the below config.
   Section "Monitor" Identifier "DisplayPort-1-0" Option "PreferredMode" "2880x1600" Modeline "2880x1600_120.00" 827.00 2880 3128 3448 4016 1600 1603 1613 1717 -hsync +vsync Modeline "2880x1600_100.00" 678.50 2880 3128 3440 4000 1600 1603 1613 1697 -hsync +vsync Modeline "2880x1600_90.00" 607.00 2880 3128 3440 4000 1600 1603 1613 1687 -hsync +vsync EndSection
2. Open 'Steam'
3. Set 'Launch Options' as DRI_PRIME=1 VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json %command%
4. Run 'SteamVR'

Expected behavior
I expect SteamVR to use my Valve Index as the display, rather than open VRCompositor on my laptop display.

Hello @shaunblyde, it might be interesting to test setting MESA_VK_DEVICE_SELECT in SteamVR's launch options in a similar way as #465 (comment). That would need to be adjusted to the pciid of your secondary GPU (maybe 1002:73df?). It should be a more explicit way to tell the Vulkan render path which GPU should be used than DRI_PRIME=1.

[shaunblyde]

@kisak-valve thanks for the suggestion, unfortunately I am still getting the same results and vrcompositor.txt still references the iGPU.
I found my dGPU id through vulkaninfo as per below, I am assuming therefore the Launch Option MESA_VK_DEVICE_SELECT=1002:73df %command% would be correct.

vendorID = 0x1002
deviceID = 0x73df

[shaunblyde]

I have found I can get SteamVR using video memory (monitoring via radeontop -b 3) using DRI_PRIME=1 %command% in Launch Options. It seems to run smoother, suggesting it is actually using the dGPU as opposed to without the launch option, but it still opens VRCompositor on the monitor rather than the Valve Index.
MESA_VK_DEVICE_SELECT=1002:73df %command% appears to make no difference, whether alone or in combination with DRI_PRIME=1
One additional strange thing is that with DRI_PRIME=1, the SteamVR overlay is messed up as shown below.

EDIT: Audio output is also not detected, not sure if this indicates a driver issue or similar? The microphone is detected, but doesn't seem to pick up any sound.

Here's how I got mine to work with your exact laptop:
Use wayland, Xwayland 22.1.0 DRM lease, Use KDE 5.24 for DRM lease support.
Put KWIN_DRM_DEVICES=/dev/dri/card0:/dev/dri/card1
In your /etc/environment and restart your display-manager to take effect. This will ignore the iGPU and run everything on the dGPU using only a frame copy to your internal monitor across the iGPU.

I do believe the linux kernel itself doesnt support leasing a display that is connected to another GPU so you must run your wayland session on your dGPU to be able to lease your headset to openvr.

You are a hero, thank you! Now to see if Gnome has any equivalent environment variable.
I'm just finding it a bit janky when I move my head around at 144 Hz, what refresh rate do you have it set at?

Hi, I think I'm running into this issue, too. I also have two GPUs here. Already wrote a comment on the closed #202 (a duplicate of this one?), which I found first, before this ticket. This is what it looks like for me and this is the hardware and the software versions I'm using: https://gitlab.freedesktop.org/monado/monado/-/issues/267

How would I properly disable the iGPU on X11+Xmonad?

Hi, can you confirm which desktop environment you're using? I could only get it going on KDE (and it was a bit janky), but I'm usually using GNOME. So I ended up just using Windows and haven't tried it again for a while, but I can do some testing.

Hi @shaunblyde, thanks for your reply! Like I wrote above, I tested it with the tiling window manager Xmonad. From reading these tickets here so far I got the impression that something might have gotten confused with the two available GPUs. But the window manager is a good point, too, I'll retry with KDE, Gnome and Mate the next time I get a chance to do so and will provide an update about my findings here.

The root issue is entirely to do with running apps across different GPUs. If on any sort of PRIME system ensure everything in use in your VR session is running on the same GPU as cross use of optimized vulkan memory segments read out wrong when reaching into other GPUs.

Just append the env var DRI_PRIME=1 to your VR session and all involved apps to resolve without having to mess with your PRIME configuration by turning it into a reverse PRIME as suggested above by me earlier.

@SpookySkeletons thanks for the suggestion! Unfortunately, for one thing DRI_PRIME=1 does not seem to fix the scrambled overlays for me. For another, this makes the VR environment appear as a window on my laptop screen instead of on the VR headset.

I'm using this https://github.com/hertg/egpu-switcher to set the eGPU as the default GPU. This tool creates the following file for me:

/etc/X11/xorg.conf.d/99-egpu-switcher.conf:
