ALVR addon doesn't appear on Steamvr

[KuraakaiGoro]

Description

I had a problem launching Steamvr, and had to reinstall Steam to get it to work. Then when I launched ALVR, the plugin no longer appeared. I tried reinstalling steamvr, and ALVR to no avail. I registered the plugin, at /usr/lib/steamvr/alvr so idk what's wrong

General Troubleshooting

• I carefully followed the instructions in the README and successfully completed the setup wizard
• I read the ALVR Wikis polygraphene's ALVR GitHub Wiki and ALVR GitHub Wiki

I might have had a similar problem with the new SteamVR update, something happened that caused SteamVR to send no steam runtime environment set, please use sniper SLR to stdout and then crash, I had to reinstall Steam to get it working back, but then ALVR didn't seem to be working at all on the newest version. Maybe try running the previous release branch as a workaround? That's what I'm currently doing.

That works. Should I keep this issue open until a permanent fix is found?

[ymndoseijin]

I guess so, as it's a problem on the main SteamVR branch

[GrigoriyPeters]

Welp. Now even the 'previous' beta branch (2.4.4) of SteamVR doesn't work for me.
SteamVR just won't register the ALVR driver.

Yep, been seeing this since yesterday evening when I tried to use ALVR. Not sure what's changed though.

[KuraakaiGoro]

I ran it just now, it still works for me, version 2.4.4
Have you tried updating ALVR? Is it blocked?

[infidelus]

Well I'm on 20.8.1 so unless I go to nightly releases (which seem to not always be nightly) there's nothing for me to upgrade to. It's not blocked. It worked on Sunday and Monday, then stopped working on Tuesday. No changes made here.

[KuraakaiGoro]

strange, I'm using the Nvidia fork on Linux if that adds any context

[infidelus]

Well, no idea what's wrong with it. Completely uninstalled & reinstalled Steam then SteamVR, ran SteamVR and closed it. Ran ALVR and it's still not showing the alvr_server add-on in SteamVR settings and it just tells me to plug my headset in now. Even tried the latest nightly.

OK, I have finally got ALVR working (at least back into the SteamVR home screen) by following the instructions at https://github.com/Scrumplex/Steam-Play-None.

Note however that that Proton-Up-Qt did not work in x11 as it complained about no QT environment. Fortunately Linux Mint recently added experimental Wayland support so once I logged back in on that I could run it, then log back into x11 and follow the rest of the instructions.

Had problems yesterday running the ALVR server, fixed by statically linking x264 in source build, and later black screens on SteamVR 2.4.4, also fixed by using https://github.com/Scrumplex/Steam-Play-None. The SteamVR container runtime issues may also be related to the x264 linking issue mentioned on #2130, so maybe the same fix would fix the server startup issue, but I haven't tried that specifically.

Thanks! Now ALVR 20.8.1 works with SteamVR 2.4.4 for me.

I'm guessing this might be related to the SteamVR update, and it's recommended to follow #2115 to configure it to verify that it's available.

SteamVR just updated to 2.6. Now workaround with setting previous version does not work, as previous version is now 2.5.

There's a better workaround, see the linux troubleshooting page of the wiki
