DriverManager monado load error libuvc.so.0: cannot open shared object file

[ccgauvin94]

Describe the bug Cannot load external drivers - 'cannot find file'

To Reproduce Steps to reproduce the behavior: 1) Copy an external driver folder into .steam/steam/steamapps/common/SteamVR/drivers (Tested with steamvr-monado and air_glasses) 2) Start SteamVR - driver will fail to load. Logs indicate that this is because it is unable to find the driver file. However, it seemingly has no problem finding the other files such as the vrmanifest.

Expected behavior Presumably the driver should load.

System Information (please complete the following information): Please use the latest Steam beta client and SteamVR beta for your bug reports!

• Steam client version (build number or date): 1721173382, also tried Flatpak
• SteamVR version: 2.62 and beta 2.7.4
• Distribution (e.g. Ubuntu): openSUSE Tumbleweed, KDE Plasma 6.1.2, KDE Frameworks 6.4.0, Qt 6.7.2, Kernel 6.9.9-1-default, Wayland, AMD Radeon 780M and AMD Ryzen 7040HS.
• Steam runtime diagnostics: [generate via Help -> Steam Runtime Diagnostics in the Steam client]

Github complains it's too long if I include this.

• Steam and SteamVR logs: [generate by running this command in a terminal tar -zcvf ~/Desktop/steam-logs.tar.gz ~/.steam/steam/logs]

I can generate these if needed, but here is the relevant output from the Web Console:

Just note, this is not monado specific, I also had the same error with the air_glasses driver.

I think that this is related to my issue #698 about containerization issues. Running vrmonitor.sh manually outside their sanbox or copying the library into one of SteamVR LD_LIBRARY_PATH may workaround this problem until VALVE decide to fix these issues.

Thanks for the hint. Unfortunately, vrmonitor.sh appears to be broken for me as well! Something is clearly off with the containerization.
