[BUG] VRCompositor dies with no errors

[Ulrar]

Describe the bug I've installed SteamVR on Arch, which is running on an MSI GS65 Stealth laptop. SteamVR works well on Windows on that same laptop. When I start SteamVR on Linux, the vrcompositor process seems to dies with no errors in the log file, and ps aux shows it defunct ;

To Reproduce Steps to reproduce the behavior:

1. Install ArchLinux on an MSI GS65
2. Setup bumblebee / primusrun and the nvidia drivers
3. Start SteamVR
4. See error

Expected behavior For SteamVR to work

System Information (please complete the following information):

• Distribution: Arch
• SteamVR version: Latest from Steam, build 8357149
• Steam client version: Latest as of 2022/05/13
• Opted into Steam client beta?: No
• Graphics driver version: [run nvidia-settings or vulkaninfo | grep driverInfo: nvidia 510.68.02 (through primusrun)
• Gist for SteamVR System Information: https://gist.github.com/Ulrar/c84b02931b926b3bb38f2e2dfb037aac

Additional context As you can probably see from the vrmonitor logs, it seems to find the headset on HDMI 0 (which is correct) through Vulkan WSI, and selects a mode then it just dies without any explanation. I'm using Gnome running in Xorg, as I usually have intel-virtual-output running to get external monitors working. The above is taken without it running though, so nothing should be holding the headset in use.

Note: Commenters who are also experiencing this issue are encouraged to include the "System Information" section in their replies.
