[BUG] Error 496 on first start of SteamVR after a boot

[anxest]

Describe the bug The first time of the day I start steamVR, I got an error 496 : "Failed to connect to headset display Your headset might not be connected, or your desktop environment might not support VR." But I do have an image in the headset: I can see the loading zone, and the Home "waiting" picture infinitely loading (this is why I register a new bug: not totally sure it's the same as #703; I didn't activated the performance graph either). What I see in the headset is not reflected on the dock VR View though. In this context, If I try to open the dashboard into my headset, the environment will darken, and I'll see the light bar that usually appear under the dashboard, but the dashboard won't display. If I quit SteamVR from the dock on the screen, the "exiting VR" will display for a good 30 seconds before effectively turning off. If I restart SteamVR after this, it will now start "normally" (except the settings will display as I mentioned in #712), letting me play. This issue will happen again after the next fresh start of my computer, or reboot.

To Reproduce Steps to reproduce the behavior:

1. Turn on the computer or reboot the computer
2. Start SteamVR
3. See error

Expected behavior Starting SteamVR normally, being able to start Home, display the dashboard and starting a game.

Which hardware are you on? Especially laptop or desktop?

It's a desktop

Might be an AMD driver problem rather than SteamVR problem. I found some issues like this over at Gitlab: https://gitlab.freedesktop.org/drm/amd/-/issues/1856 https://gitlab.freedesktop.org/drm/amd/-/issues/2342 https://gitlab.freedesktop.org/mesa/mesa/-/issues/7041

This happens to me too with Valve Index and Radeon 6800XT. Sometimes even happens with Monado, where Monado will crash in the first start after a reboot. Then I have to start SteamVR, let it crash, choose "Restart Headset" in the SteamVR vrmonitor menu, which will recover the headset to a working state and then start Monado or SteamVR again.

I experience similar behavior on my system; SteamVR fails to connect to headset, and then resumes fine after I've either restarted or disconnected and reconnected headset. Though manifesting differently through the updates (the result was always the same: somehow or another restart headset), it has lasted for about a year (as long as I've owned this system).

Currently, the details are different than yours but I'm unsure if they mean that I have to make a separate issue. My process is as follows:

• Start system, then login.
• Start Steam, then SteamVR. In the Steam window, it says that SteamVR failed to launch; in the SteamVR window, it says that it cannot connect to headset. In the performance graph, there are no frametimes submitted.
• Restart the headset using SteamVR's menu. Restart SteamVR.
• Sometimes I may additionally need to logout, disconnect all cables from the headset, login, then reconnect all cables. I start SteamVR afterward.
• I observe that the SteamVR window opens, there are no errors submitted, and the frametime graph becomes populated with data. Everything works as expected.
• I logout, then log back in. Start SteamVR. Everything works as expected. Every time my system reboots, it reverts back to the previous behavior.

For completeness, here are my system details: CPU: AMD Ryzen 7 7800X3D GPUs: AMD Radeon RX 7800 XT (Primary), iGPU (Secondary, no display connection); with no PRIME setup Memory: 32GB with 96GB Z-swap Headset: Valve Index Kernel: Linux 6.6.38-1-lts GPU Driver: Mesa 24.1.3 Distro: Arch Linux 64-bit DM: KDE Plasma 6.1.2 running Wayland
