To Reproduce Steps to reproduce the behavior:

  1. Launch SteamVR and monitor terminal outputs for obvious error.

Expected behavior be able to launch vrcompositor-launcher without pkexec or elevation issues under flatpak

System Information (please complete the following information):

Additional context Some output from Steam. Also it does fail to initialize SteamVR on startup, but that may be normal.

+ pkexec setcap CAP_SYS_NICE=eip /home/theriddick/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher

It's possible to run $HOME/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/SteamVR/bin/vrstartup.sh directly but I don't know if that will solve the problem correctly when linking with ALVR or other apps etc...

Run

sudo setcap CAP_SYS_NICE+ep ~/.var/app/com.valvesoftware.Steam/data/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher

And no it has nothing to do with ALVR just how flatpak is with apps not explicitly built for it and I'm not sure you could it's complicated to say the least

Vixea commented 1 year ago

Also make sure you are building alvr with the flatpak version of ALVR any other version isn't going to work(you need to build it yourself)

fair enough, for now I've moved back to system runtime steam for better performance anyway.

Thanks for help. I'll close this now.
