title: My VR Hell on NixOS
|
|

|
|
Recently I got a new VR setup that uses my tower directly instead of the [wifi
|
|
streaming
|
|
catastrophe](https://christine.website/blog/convoluted-vrchat-gchat-setup-2021-02-24).
|
|
I have a [Valve Index](https://store.steampowered.com/valveindex) and an [AMD
|
|
RX6700XT](https://www.amd.com/en/products/graphics/amd-radeon-rx-6700-xt) GPU.
|
|
Some huge advantages of this setup include:
|
|
|
|
* Being able to use Linux instead of being railroaded into using Windows for my
|
|
V-tubing streams. I would like to do some more v-tube style content (maybe
|
|
including maybe some NixOS hacking streams in Lojban in the future), and
|
|
honestly I feel that the look of me being a super Linux hacker person [visibly
|
|
using Windows Terminal in streams](https://youtu.be/ntTibBgi_Fg) is very
|
|
wrong. [Yes I know Windows 11 has Wayland support for running GUI programs that
|
|
way, but I am not going to be an unpaid beta tester for a trillion dollar
|
|
company that wanted to fire its QA team so that they could get more number on
|
|
a spreadsheet even though they have so throughly saturated the market that
|
|
it's nearly impossible to displace them, which makes future growth frankly
|
|
ridiculous.](conversation://Cadey/angy)
|
|
* Lower latency in my VR experiences. Fear is the mind killer, and latency is
|
|
the immersion killer. With this new setup things feel _instant_, especially
|
|
with the 144hz of the Valve Index (my Quest 2 only got up to 120hz at most,
|
|
but over wifi the only stable frame rate I could get was 72hz due to VR and
|
|
the video encoding fighting for GPU time).
|
|
* Full-body tracking support with the Index lighthouses. This will mostly be for
|
|
me in VRChat and maybe when [working out in Beat Saber
|
|
streams](https://youtu.be/AvPjHweTFxc).
|
|
* Not having Facebook in the loop. [We will not be respecting Facebook's name
|
|
change until they file the appropriate court order and get their identity
|
|
documents updated everywhere, if only as revenge for their transphobic
|
|
"real name" policies.](conversation://Cadey/enby)
|
|
* The headset has a pair of headphones built in so I don't have to move my
|
|
headphones between devices constantly.
|
|
[I'd argue they're very directionalized speakers.](conversation://Mara/hacker)
|
|
|
|
As expected, it works great on Windows. As the title infers, it does NOT work
|
|
well for me on NixOS.
|
|
|
|
[This is not a blogpost, it's a cry for help.](conversation://Numa/delet)
|
|
|
|
Here is the saga of things I have tried.
|
|
|
|
## Limbo
|
|
|
|
First I tried the naïve route. I just plugged everything in and decided to see
|
|
what happens with SteamVR. I installed SteamVR through NixOS natively
|
|
(specifically choosing the "pretend to be Ubuntu" route in order to minimize
|
|
downsides due to ABI demons), and the headset showed right up.
|
|
|
|
I opened SteamVR and I got a prompt asking me to make some changes with root. I
|
|
was expecting this, doing stuff with raw hardware like you need to with VR does
|
|
require some root privileges, and this was likely for blessing the SteamVR
|
|
programs to not require running as root all the time. I hit `yes`, typed in my
|
|
password and SteamVR stopped showing as "Launching" on the Steam UI.
|
|
|
|
I killed Steam completely and then relaunched it from a terminal so I could see
|
|
the logs to standard out.
|
|
|
|
[Pro tip, apparently GNOME runs every application in its own systemd slice
|
|
(which really does explain why GNOME has a hard requirement for systemd as well
|
|
as why the "Force Quit" button actually seems to work reliably and clean up all
|
|
the associated clutter in one fell swoop), so you can fetch this stuff from your
|
|
user journal with `systemctl --user status` to find the slices (type `/steam`
|
|
and hit the enter key to search for it) and `journalctl --user -u $name.slice`
|
|
to look through their output that way.](conversation://Mara/hacker)
|
|
|
|
Turns out that the blessing was to give the SteamVR compositor permissions to
|
|
run as a real-time process. This makes sense. VR is something where minor delays
|
|
can be the difference between being totally fine and puking your guts out due to
|
|
motion sickness. Running the VR compositor as a realtime process is completely
|
|
understandable because it reduces the chance of any possible delay in the
|
|
scheduler.
|
|
|
|
However, on NixOS this just makes the SteamVR compositor crash for some reason.
|
|
Never really got a good answer as to why, just that you should never let it set
|
|
those permissions for any reason.
|
|
|
|
So to get it even to a point where things would work, I told Steam to completely
|
|
delete SteamVR and then reinstalled it from scratch. I hoped that my config
|
|
would get nuked and I could start over. My config got nuked and I got everything
|
|
set up again, making sure to choose "No" on the "SteamVR needs root access for
|
|
additional setup" prompt.
|
|
|
|
[As an aside, it seems that most of the people that do VR on NixOS that I know
|
|
use Nvidia cards. Nvidia drivers on NixOS seem to be significantly less cursed
|
|
when compared to other distros, however when I built this tower I was building
|
|
it assuming that I would primarily run NixOS on it. This made me pick an AMD
|
|
card even though they have slightly less waifus per second compared to their
|
|
Nvidia counterparts. However the fact that `amdgpu` is in the damn kernel by
|
|
default and the AMD team works _with_ mesa to make things work well was the
|
|
selling point for me. Maybe I should try an Nvidia
|
|
card?](conversation://Cadey/enby)
|
|
|
|
## Lust
|
|
|
|
After that, everything worked as I expected out of the box for playing VRChat,
|
|
which was surprising. I had switched to Xorg from Wayland a while ago in
|
|
preparation for this (for some reason VR on Wayland ranges from "lol" to "you're
|
|
totally screwed"), and I was ready to get off to the races.
|
|
|
|
[That Wayland comment seems ominous...](conversation://Mara/hmm)
|
|
|
|
Then I tried to open the SteamVR overlay. Nothing happened. I looked at my
|
|
controllers in VR and it seemed like the occlusion model was backwards:
|
|
|
|
<center>
|
|
|
|
|
|
|
|
</center>
|
|
|
|
I can deal with this, but it certainly _feels_ weird this way.
|
|
|
|
[This is when I knew I was in for a ride.](conversation://Cadey/facepalm)
|
|
|
|
The thing that surprised me the most was that the audio stack worked instantly
|
|
the way I expected. All the audio moved over to the headset and the default
|
|
microphone device was set to the headset and **EVERYTHING RESPECTED THAT WITH NO
|
|
FURTHER CONFIGURATION**.
|
|
|
|
[This article is mostly about struggles with Linux, but the struggles with
|
|
Windows are real too. For some reason on Windows the default speaker device will
|
|
get moved over to the Index without issue, but the default **microphone** will
|
|
not. I have not been able to find any way to fix this and it doesn't happen with
|
|
my husband's Index so I assume this is just either me or Discord being utterly
|
|
and irrevocably cursed beyond repair.](conversation://Cadey/facepalm)
|
|
|
|
Not having the SteamVR overlay is a nonstarter for me. I use the SteamVR overlay
|
|
to move between games, tweak graphic settings on the fly and fiddle with the
|
|
desktop should I need to.
|
|
|
|
## Gluttony
|
|
|
|
So I started tinkering with settings, kernel versions and more to try to get
|
|
more things working. Keep in mind that at this point I had a mostly functional
|
|
setup on NixOS. I could play games, but the ergonomics for moving between games
|
|
ranged from "lol" to "walk over to the PC every time to open the game manually
|
|
and wait for the shaders to compile".
|
|
|
|
I had heard that the flatpak version of Steam was less cursed by a friend of
|
|
mine who seems utterly convinced that flatpak is the next coming of sliced
|
|
bread. [Flatpak](https://flatpak.org/) seems like one of those things that you
|
|
come up with when you want all the advantages of Nix but really really love
|
|
YAML. Flatpak is a valid strategy for packaging complicated software like this
|
|
because the sandboxing and discrete platform runtime strategy would make it _so
|
|
much easier_ to handle the levels of cursed involved with getting otherwise ABI
|
|
conflicting things to run consistently across distros.
|
|
|
|
So I tried Flatpak Steam. One annoying part about installing stuff in Flatpak is
|
|
that Flatpak prefers to put things in `.desktop` files that are registered to
|
|
your desktop environment's program launcher instead of putting a name in your
|
|
`$PATH`. This also makes sense because they are obviously targeting GUI apps and
|
|
doing it that way would likely make life a lot easier for GUI apps. Then keep in
|
|
mind that I want logs to see what is going on so I can have _any hope_ of
|
|
frantically googling things to understand how to fix this. Mind you this is
|
|
before the trick involving systemd slices was revealed to me so I didn't have
|
|
any other way to get output directly.
|
|
|
|
[Yes I know SteamVR on Linux has logfiles. I was in struggle mode and just
|
|
wanted to be able to scroll up and see what went wrong.](conversation://Cadey/coffee)
|
|
|
|
I wrote this script to launch Flatpak Steam called `steam2`:
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
export SDL_VIDEODRIVER=x11
|
|
exec flatpak run com.valvesoftware.Steam
|
|
```
|
|
|
|
I then ran it, logged in, enabled global Steam Play, restarted Steam, installed
|
|
SteamVR and VRChat and then set up my playspace again. I put on the headset and
|
|
things didn't totally work. The overlay was still broken. At this point I was
|
|
starting to have thoughts like:
|
|
|
|
[Okay, is NixOS broken, is Steam broken, is SteamVR broken, or am I
|
|
broken?](conversation://Mara/hmm)
|
|
|
|
At least I was able to log into VRChat and go to a public world. I went to [The
|
|
Black Cat](https://vrchat-legends.fandom.com/wiki/The_Black_Cat) and asked
|
|
someone there if they could hear me. They could and wondered what was going on.
|
|
I told them I was from the future and to not worry and then closed VRChat after
|
|
saying "oh no, the connection is fading, make sure you remember the secret of
|
|
life, the universe, and everything is-". I had gotten things somewhat working
|
|
and I was fairly exhausted at this point, so I decided to call it a day and
|
|
headed to bed.
|
|
|
|
## Greed
|
|
|
|
At the advice of a trusted friend, I tried running everything in Wayland.
|
|
Wayland works at a much lower level with the GPU, so it should probably have a
|
|
bit of an easier time. I unmasked wayland sessions and sway from my NixOS config
|
|
and then rebooted and logged into sway.
|
|
|
|
Out of the corner of my eye I saw the VR headset light up like it had video
|
|
rendering to it. This struck me as odd, because there's a special xrandr
|
|
property to tell display servers "hey you dingus, this isn't a monitor: don't
|
|
treat it as one":
|
|
|
|
```
|
|
DisplayPort-1 disconnected (normal left inverted right x axis y axis)
|
|
<...>
|
|
non-desktop: 1
|
|
range: (0, 1)
|
|
2880x1600 144.00
|
|
```
|
|
|
|
The resolution and refresh rate match [the specs for the
|
|
Index](https://en.wikipedia.org/wiki/Valve_Index) if you put both 1440x1600
|
|
panels next to eachother as one big screen (most of the time they do this at the
|
|
manufacturing/software stage so that game engines can render one weirdly skewed
|
|
image to the "screen" and not have to manage two separate framebuffers that
|
|
could get out of sync, turning weaker people into vomit cannons). If you haven't
|
|
ever tried to look at Discord badly rendered to a VR headset before, you aren't
|
|
missing out on much. I then made a change to my sway config to tell sway to
|
|
disable the Valve Index output:
|
|
|
|
```nix
|
|
cadey.sway.output."DP-2".disable = "";
|
|
```
|
|
|
|
[This is also ominous...](conversation://Mara/hmm)
|
|
|
|
Then I rebuilt my config, sway picked up on it and then turned off the headset
|
|
view. I launched SteamVR and then it started rendering to the desktop. If you've
|
|
never seen what it looks like when a VR headset starts rendering to the desktop
|
|
instead of to the headset directly, it looks something like this:
|
|
|
|
|
|
|
|
I told SteamVR to restart in "direct display" mode, but it was failing because
|
|
SteamVR couldn't restart due to a missing dynamic library problem:
|
|
|
|
```
|
|
/home/cadey/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/restarthelper: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory
|
|
```
|
|
|
|
This is not good. I don't have a working setup in Wayland. Sway is fairly low
|
|
level and boring as far as Wayland compositors go, so an incompatibility here
|
|
has to point to something much more low level right? Turns out that Wayland
|
|
(more specifically XWayland) doesn't support the rigging needed in order to have
|
|
the SteamVR compositor yank a display for itself (specifically via the Vulkan
|
|
extension `VK_EXT_direct_mode_display`), so it will probably never work until
|
|
that is supported.
|
|
|
|
This is annoying, but understandable to a point. Wayland is still fairly new and
|
|
has to compete with an ungodly number of hacks that have been put into Xorg over
|
|
the years for weird cases like this.
|
|
|
|
## Anger
|
|
|
|
So I disabled Wayland/sway in my NixOS config, rebooted (just to be sure, you
|
|
can never totally be sure with display managers) and then tried SteamVR via
|
|
native Steam again. Surely it had to work, right?
|
|
|
|
Nope. It rendered to the desktop again. Hitting restart got that same "cannot
|
|
open shared object file" error. Restarting it manually got a different error
|
|
though:
|
|
|
|
|
|
|
|
This seems to be a sort of "catchall" error in SteamVR for when something really
|
|
wrong happens at lower parts of the stack. Googling for this mostly got people
|
|
running into this with Nvidia cards, and nearly always the fix for them was
|
|
"reinstall your GPU driver". That both doesn't make sense for me and is kind of
|
|
impossible because my AMD card uses `amdgpu`, which is a part of the Linux
|
|
kernel and can't really be "reinstalled" arbitrarily on NixOS.
|
|
|
|
[NixOS is effectively a "build everything from source" distribution with a
|
|
binary cache that is used to cheat your way out of not having to build things
|
|
from source. So when you "install" a package you are really downloading it from
|
|
the NixOS cache server (or building it if it doesn't exist there) and then
|
|
telling Nix to symlink it to the right place. In this model, it doesn't really
|
|
make sense to be able to "reinstall" packages.](conversation://Mara/hacker)
|
|
|
|
I went through a lot of settings, messed with X and more but got nowhere. I was
|
|
running strace on the SteamVR compositor at one point but still had no real
|
|
clear path forward.
|
|
|
|
The same trusted friend that told me to try Wayland was flabbergasted at this
|
|
point. This kind of error makes _absolutely no sense_ yet here we are, living
|
|
it!
|
|
|
|
## Heresy
|
|
|
|
I was asked to try a "normal" distribution out. Seeing as that Valve has been
|
|
like:
|
|
|
|
<center>
|
|
|
|
|
|
|
|
</center>
|
|
|
|
I thought that I should choose [Arch Linux](https://archlinux.org/) to verify
|
|
this against. Arch is the basis for the new version of SteamOS, so surely this
|
|
should work better, right?
|
|
|
|
[What is it with you and being so ominous?](conversation://Mara/hmm)
|
|
|
|
So I downloaded the Arch iso, wrote it to a flashdrive and then booted my tower
|
|
off of it. My disk layout looks a bit like this:
|
|
|
|
<center>
|
|
|
|
|
|
|
|
</center>
|
|
|
|
[At some point I am intending to reinstall NixOS on my tower with a ZFS root,
|
|
but today is not that day.](conversation://Cadey/coffee)
|
|
|
|
However the Archive partition is almost completely unused after I moved
|
|
everything over to [the NAS](/blog/my-homelab-nas-2021-11-29), save a few Steam
|
|
games that I could just redownload anyways. My Data drive is used mostly for
|
|
Beat Saber custom songs, Unity project backups and other things I would really
|
|
rather not wipe out, so I decided to use the Archive drive as my sacrificial
|
|
lamb for Arch.
|
|
|
|
[You mentioned that you put Steam games on the Data drive, given that it's btrfs
|
|
and this whole article is about things not working on NixOS, how did you even
|
|
use it?](conversation://Mara/hmm)
|
|
|
|
[I use <a href="https://github.com/maharmstone/btrfs">winbtrfs</a> to mount
|
|
btrfs volumes on windows. I'm using btrfs here because at the time I did the
|
|
partitioning of my drives btrfs was the most Linux and Windows-compatible
|
|
filesystem that I could use to just store data on both Windows and Linux and
|
|
have each side access it from the other. I also needed btrfs so that I could put
|
|
Steam games on it and have Windows and Linux both be able to use them. There's a
|
|
lot of subtle bugs involved in using NTFS-3g on NixOS with Steam games in
|
|
particular, so using a native kernel supported filesystem was vital. Otherwise I
|
|
would have used something better like ZFS.](conversation://Cadey/enby)
|
|
|
|
One of the more painful parts about Arch Linux is that there's no installer. You
|
|
have to do things by hand. This gives you a lot of power (you can easily do
|
|
really cursed configs like it was nothing, such as [installing Arch on
|
|
NTFS](https://github.com/nikp123/ntfs-rootfs)), but at the same time it means
|
|
that there is a lot more time investment required to just get the computer
|
|
working. Recently they added
|
|
[archinstall](https://wiki.archlinux.org/title/Archinstall) as an easy way to
|
|
just install Arch with a known set of defaults. This made it way less painful
|
|
for me to install Arch to the Archive drive.
|
|
|
|
I booted into Arch, followed the instructions to run `archinstall`, went through
|
|
the prompts, set up a root password, then finally selected the KDE profile.
|
|
|
|
[Get it? KDE? Cadey-e?](conversation://Cadey/enby)
|
|
|
|
[Hey Siri, how do you delete someone else's post?](conversation://Numa/delet)
|
|
|
|
After `archinstall` claimed victory, I rebooted into Arch and was greeted with a
|
|
login screen that told me to pick a user and type in a password, but there were
|
|
no options to pick from. This meant I needed to hack into the system to get to
|
|
the point where I could login to the desktop.
|
|
|
|
[I was prepared for a fight, but this felt like the installer bit
|
|
me. I am not sure if this was the result of me using the installer wrong or the
|
|
installer not caching this case and making me make a user account so that I
|
|
could log in. I'm not sure if I should file a bug about this or
|
|
not.](conversation://Cadey/coffee)
|
|
|
|
Control-Alt-F1 didn't work. This made me think there was some shenanigans going
|
|
on with the Xorg config such as disabling the CHVT bindings. So I rebooted into
|
|
the boot menu and pressed `e` to edit the boot string. I appended `init=/bin/sh`
|
|
to the argument string to force Arch to drop me into a root shell. It proceeded
|
|
to drop me into a root shell and then dutifully ignored all of my attempts at
|
|
keyboard input. It behaved like the USB module wasn't loaded, which is weird to
|
|
me as I usually expect the USB module to be part of the kernel proper. I
|
|
rebooted back into Arch's login screen to try and rethink my strategies.
|
|
|
|
After debating getting the PS/2 crash cart keyboard out, my husband tried
|
|
pressing various Control-Alt-F${N} keys and eventually got one that gave us a
|
|
login prompt. I felt like a dunce.

</center>
|
|
|
|
I managed to log in and create a user account, then set a password and used that
|
|
account to hack into the matrix. Once I installed Steam (after enabling
|
|
`multilib` and 12 parallel download threads), I launched it to see that it did
|
|
not detect the VR headset. I suspect that there was probably some group or
|
|
combination of groups that I missed and I really wanted to have a more curated
|
|
experience. Steam not detecting the Index really killed Arch for this testing
|
|
phase and left me frustrated.
|
|
|
|
## Violence
|
|
|
|
Suddenly a glint of philosophical brilliance struck me and I remembered this
|
|
wisdom:
|
|
|
|
<center>
|
|
|
|
|
|
|
|
</center>
|
|
|
|
I had a Manjaro USB laying around from when I was trying to sucker my husband
|
|
into trying to use it, so I threw that into my tower and then replaced Arch with
|
|
Manjaro. Manjaro is great. You just install it and it works. That's everything I
|
|
wanted out of this. I wanted to just install the thing and then the computer
|
|
does the computerbox stuff. It was really cool that Steam came preinstalled!
|
|
|
|
The default Manjaro experience is _really nice_. I really like how integrated
|
|
and snappy the system _feels_. It's really just Arch with training wheels, but
|
|
they ship a handbook that is really nice as a reference manual. I should really
|
|
have started with Manjaro for this part of the process instead of using Arch,
|
|
but I blame that on [the twitter
|
|
poll](https://twitter.com/theprincessxena/status/1466162147734573070?s=20). If
|
|
you want a decent first experience with desktop Linux, try Manjaro out. It's
|
|
really a lot better than you think it is. Things have gotten so much better than
|
|
they were in the Vista era when I started using Linux on the desktop.
|
|
|
|
[Let's be honest, most of your work is done in browsers or electron apps
|
|
anyways. You'll be fine!](conversation://Mara/happy)
|
|
|
|
Steam was preinstalled, but sometimes it complained about needing some system
|
|
libraries to function. This felt weird to me, because Valve started shipping the
|
|
Steam Linux Runtime which essentially includes all of those libraries, but it
|
|
turns out that was actually really a problem. I didn't try too hard to solve it
|
|
though because it was working enough to install and run SteamVR.
|
|
|
|
I set up SteamVR and it rendered stuff to the headset. This was promising! The
|
|
SteamVR overlay still didn't work though, but at this point I was almost
|
|
expecting it. The weird part though was the fact that the SteamVR configuration
|
|
tool was missing almost all of its UI elements. That pointed me at a few ideas
|
|
and I ran SteamVR in another terminal window again with no conclusive results.
|
|

I did a round of microphone testing, and it looks like the audio from the
|
|
microphone wasn't being picked up. This was odd, it worked fine in NixOS.
|
|
|
|
At least I didn't need to be afraid of the `setcap` hack that SteamVR tries to
|
|
apply on start. That seems to work reliably without causing issues.

## Fraud
|
|
|
|
I'm not sure how I came across [this Reddit post on
|
|
`/r/ValveIndex`](https://www.reddit.com/r/ValveIndex/comments/lmo1ku/a_comprehensive_guide_to_getting_your_valve_index/),
|
|
and I am so glad I did. Most of the problems with Steam itself were due to
|
|
needing to run this command:
|
|
|
|
```
|
|
sudo pacman -Sy steam-native linux-steam-integration
|
|
```
|
|
|
|
This will install all of the aforementioned native libraries that Steam was
|
|
complaining about. Also make sure you are using Xorg for this. At the time of
|
|
writing this post, Manjaro KDE defaults to using Xorg. In the future you may
|
|
need to set the default to Xorg. However in the future Valve is probably going
|
|
to fix the SteamVR on Linux jank (especially if the rumors about project Deckard
|
|
are true), so it may work fine with Wayland then.
|
|
|
|
[Manjaro should really make those packages part of the default install set, if
|
|
only to make it more seamless.](conversation://Mara/hacker)
|
|
|
|
To fix the microphone (and some minor audio issues with the speakers), you need
|
|
to change the default audio sample rate of PulseAudio. PulseAudio defaults to a
|
|
44,100hz for speakers and microphones. This is normally fine. Most audio is
|
|
usually at or below there, but the Valve Index expects 48,000hz. The way you get
|
|
that fixed is to customize the PulseAudio config files for the system and for
|
|
your user account like so:
|
|
|
|
1. Open `/etc/pulse/daemon.conf` as root using your favorite text editor
|
|
2. Go to the end of the file
|
|
[Press `G` in vim to jump all the way to the end of the current buffer.
|
|
Conversely `gg` will take you back to the top.](conversation://Mara/hacker)
|
|
3. Add the line `default-sample-rate = 48000`
|
|
4. Open `~/.config/pulse/daemon.conf` as your unprivileged user account
|
|
5. Go to the end of the file
|
|
6. Add the same line
|
|
7. Either reboot your PC or run `pulseaudio -k` to restart the sound server and
|
|
pick up those changes
|
|
8. Open the volume control and shout towards your headset, you should see the
|
|
audio meter moving
|
|
|
|
The SteamVR overlay not working is actually because of a missing library in the
|
|
SteamVR library bundle. It is a really dumb one too. The library `fontconfig` is
|
|
missing from the installset. They might have assumed that it would be part of
|
|
the system or something, but its absence makes `vrwebhelper` crash on launch.
|
|
Apparently the SteamVR overlay is done by `vrwebhelper`, so it crashing is
|
|
doubleplus ungood.
|
|
|
|
[These instructions are cribbed from <a href="https://www.gamingonlinux.com/2021/11/steamvr-overlay-not-working-on-arch-or-manjaro-linux-heres-a-fix/">this article</a>.](conversation://Mara/hacker)
|
|
|
|
You can fix it by first identifying where `vrwebhelper` is installed. At the time of
|
|
writing, Steam defaults to putting it in this folder:
|
|
|
|
```
|
|
~/.local/share/Steam/steamapps/common/SteamVR/bin/vrwebhelper/linux64/
|
|
```
|
|
|
|
Open `vrwebhelper.sh` and find the line that looks like this:
|
|
|
|
```shell
|
|
export LD_LIBRARY_PATH="${STEAM_RUNTIME_HEAVY}${LD_LIBRARY_PATH+:$LD_LIBRARY_PATH}"
|
|
```
|
|
|
|
and replace it with this:
|
|
|
|
```shell
|
|
export LD_LIBRARY_PATH="${DIR}:${STEAM_RUNTIME_HEAVY}${LD_LIBRARY_PATH+:$LD_LIBRARY_PATH}"
|
|
```
|
|
|
|
Then download Steam's vendored version of
|
|
[freetype2](https://github.com/ValveSoftware/SteamVR-for-Linux/files/7425064/freetype2-2.10.4-libs.tar.gz)
|
|
(I made a copy
|
|
[here](https://xena.greedo.xeserv.us/pkg/freetype2-2.10.4-libs.tar.gz) in case
|
|
the bitrot fairy strikes again) and put all the files in that archive into your
|
|
`vrwebhelper` folder. Restart Steam (and SteamVR) just to be sure, then your VR
|
|
overlay should work.
|
|
|
|
[Hopefully these hacks should not be needed in the
|
|
future.](conversation://Cadey/coffee)
|
|
|
|
At this point, everything worked. I could play games like nothing was out of
|
|
place, and the only difference I felt was that it was slightly more bouncy on
|
|
Manjaro than it was on Windows. I don't totally know how to quantify this
|
|
feeling or get a good recording of it, but it _felt_ different enough that I
|
|
feel I need to mention it.
|
|
|
|
You can still see through your controllers, which I assume is a SteamVR on Linux
|
|
problem at this point. It's the most bizarre thing, it's like the rendering
|
|
priority for the controller models is backwards.
|
|
|
|
I was able to play a few rounds of Beat Saber for testing, and the only downside
|
|
I noticed was that sometimes a few frames had a shower of green blotches. There
|
|
was no pattern.

|

|
## Treachery
|
|
|
|
[There were a couple things earlier in this post that were kinda sus. For one
|
|
you disabled the Index output in sway with that config change and then it
|
|
stopped working in Xorg. Was the first line about the headset in `xrandr --prop`
|
|
normal? Do you see it in Manjaro?](conversation://Mara/hmm)
|
|
|
|
```nix
|
|
cadey.sway.output."DP-2".disable = "";
|
|
```
|
|
|
|
```
|
|
DisplayPort-1 disconnected
|
|
```
|
|
|
|
[Why are things 0-based in Xorg but 1-based in Wayland?](conversation://Cadey/wat)
|
|
|
|
So I made [this
|
|
commit](https://github.com/Xe/nixos-configs/commit/4683dc68173eb79348de150713f3a1b1910d9d4d)
|
|
to my NixOS configs, rebuilt my config to re-enable Wayland, booted back into
|
|
sway and then found that it was still broken.
|
|
|
|
What am I doing wrong here? I'm willing to try any ideas you all have. This is a
|
|
cry for help. I literally have no idea what I am doing wrong and this is
|
|
_really_ starting to bother me. Did I taint a state file used by display
|
|
handling? I thought this stuff was mostly if not entirely stateless to avoid
|
|
these kinds of problems. Do I need to reinstall NixOS from scratch? Should today
|
|
be the day that I set up ZFS on my tower? Is this just some kind of weird cruft
|
|
that has accumulated over a few years even though that should be _categorically
|
|
impossible_? Is the flatpak broken with SteamVR? Is the NixOS Steam package
|
|
broken? What is even going on?
|
|
|
|
Hopefully I can follow this up with a part 2 containing the really really dumb
|
|
solution. I've tried everything I can think of and have managed to really
|
|
confuse a GPU driver developer friend of mine in the process. I just want this
|
|
to work. I can get my VR fix on Windows in the meantime, but I would really love
|
|
to be able to do all this from my NixOS install.
