Installation path could not be located (111)

[anoadragon453]

Your system information

• Steam client version (build number or date): Feb 21, 2017
• Distribution (e.g. Ubuntu): Arch Linux
• Opted into Steam client beta?: [Yes/No] Client and SteamVR
• Have you checked for system updates?: [Yes/No] Yes

Please describe your issue in as much detail as possible:

When starting SteamVR the compositor shows up correctly and displays full what the headset should be seeing (controllers can be seen as tracked through this window) however the headset display does not turn on.

Shortly after the SteamVR Compositor window appears, the error message "SteamVR failed to initialized (typo btw) for unknown reasons. (Error: Config path could not be located (111))" shows up. The indicator light on the side of the headset is green, but its display is off.

Room setup will crash immediately after launching.

I've tried running with the Steam runtime with nvidia (378.13-2) and nvidia-beta (378.13-1) drivers, but both give the same issue.

Log during error.

My setup consists of two 1440p monitors over DVI with the headset running over HDMI. I have a Nvidia GTX 970.

Steps for reproducing this issue:

1. Start SteamVR Beta Client
2. Watch as SteamVR Compositor appears and works correctly (albeit displaying 1080p on a 1440p monitor)
3. Error message with title "Error Starting SteamVR" appears stating: "SteamVR failed to initialized for unknown reasons. (Error: Config path could not be located (111))"

I also get the following in dmesg:

Same error reported on my machine at startup Config path could not be located (111). Doesn't seem to be causing an issue as SteamVR appears to be working (rendering the waiting room) and I was able to run room setup.

I am using the exact drivers specified in the readme 375.27.10 from the PPA mentioned, you can add it as shown below.

sudo add-apt-repository ppa:mamarley/nvidia-dev

Like the readme says you may need to pin this higher than the graphics-drivers PPA, in my case I just disabled the graphics-drivers PPA and installed 375.27.10 from the Additional Drivers menu.

[anoadragon453]

Thanks for the response, perhaps it is a driver issue then. As I said in the OP I'm running Arch Linux which is already on a later version of the driver and there isn't an LTS package for 375.27.10 that I can see.

I can try searching for the older release, installing it may be as simple as changing the PKGBUILD but as this is my work machine I'm wary of trying to hack together nvidia driver installs.

Perhaps you could try upgrading to the latest (378.13-1/2) nvidia driver and seeing if the headset still displays content? I'm not aware of it being available in an easy to install (.deb) format yet however.

[connerbrooks]

My bad, missed that in your description, for some reason I just assume everyone is on *buntu.

I haven't messed much with Nvidia drivers on Arch (only ran on a ThinkPad), but could you just run the .run file from https://developer.nvidia.com/vulkan-driver. I have never had an easy time with their .run installer, so beware I suppose.

[kkriehl]

I have the same error, but additionally the room setup crashes with the message Failed to fetch KHX shared memory extension functions. I concluded that the required NVIDIA beta driver 375.27.10 is not an (outdated) typical beta release of an upcoming driver version, but a separate developer beta with still experimental and unreleased VULKAN features that are required by SteamVR. So to use SteamVR on Arch we have to install this developer beta driver. I hope that doesn't require downgrading other packages.

The easiest way should be by using the linked PPA debian/ubuntu package and a PKGBUILD to create an AUR package (unfortunately AUR does not have a package for the developer driver). I'll see how far I'll come without X11 failing :D. If everything works I'll publish a Gist of the PKGBUILD.

[johnv-valve]

NVIDIA cards require version 375.27.10 of the NVIDIA Developer Beta Driver.

Not 378.13.

[anoadragon453]

@kkriehl Thanks for your insight, and good luck on the PKGBUILD creation. I'll do my own testing once I get home today.

@johnv-valve As @connerbrooks receives the same 111 error with the correct Nvidia driver perhaps we should keep this issue open?

[johnv-valve]

@connerbrooks issue is different as his SteamVR works fine. If you want to create a new issue for the spurious message (I think it might just be a first run thing) then do that.

[anoadragon453]

@johnv-valve I'll create a new issue if I still receive the error after installing the new driver, unless @connerbrooks wants to go ahead and do it if he's still getting the same issue.

[hcorion]

Subscribing to this thread for that PKGBUILD @kkriehl. It would be good if you posted it on the official archlinux aur as well.

[anoadragon453]

@hcorion @kkriehl I've created a thread on the SteamVR Linux forums with current PKGBUILD progress:

https://steamcommunity.com/app/250820/discussions/5/133257959063392200/

[johnv-valve]

When you have it working, please send a pull request for README.MD in this repo with instructions.

[anoadragon453]

@johnv-valve Will do once it goes live.

[anoadragon453]

@johnv-valve PR added. No longer receiving the Installation path error anymore, though I'm unsure if this is related to the driver or the latest Feb 23 Steam beta.

Edit: Nevermind, still getting the error. Room setup does launch successfully however, which is a huge plus :)
