Linux Steam version crashes on startup (segfault)

[RainOrigami]

Describe the bug
The Steam version of OpenVR-AdvancedSettings refuses to start. It works fine with the AUR version. The log from Steam when trying:

To Reproduce
Steps to reproduce the behavior:

1. Get Manjaro Linux
2. Install steam-native
3. Install ovras through steam
4. Install required dependencies (from building_for_linux document)
5. Run SteamVR
6. Run ovras

Expected behavior
Ovras to start and put the ovras settings button in my SteamVR menu.

Screenshots
See log above.

Software (please complete the following information):

• OS: Manjaro Linux x86_64 Kernel 5.10.53-1-MANJARO
• Advanced Settings Version: 5.3.2

Hardware (please complete the following information):

• CPU: AMD Ryzen 5 3600 (12) @ 3.600GHz
• Graphics Card: NVIDIA GeForce RTX 2080 SUPER
• HMD: Valve Index

Additional context
Deleting /home/myuser/.config/AdvancedSettings-Team/OVR Advanced Settings.ini between launches of different versions (AUR/Steam) yielded no different result. Note that initially only the Steam version was installed but since it didn't start and yielded no useful output I installed the AUR version which complained about missing Qt5 packages. After installing them and the AUR version starting I expected the Steam version to work as well since all missing dependencies seemed to be installed now.
The log file /home/myuser/.local/share/AdvancedSettings-Team/AdvancedSettings.log only shows the same lines as the steam log above, excluding the segfault and trailing lines.
I wished I had a clue how AppImage files work and how to get any actual useful information from the crash instead of just segfault. When running the AUR version without the required dependencies it would at least print an error relating to the issue but the AppImage version just crashes.

I might have more information that may be useful. I've ran the AppImage using gdb and the output and stack is as follows:

Thanks for the excellent issue report.

I believe this is related to issue #455.

Could you ensure that the libxkbcommon-x11.so.0 file has been removed from the AppImage?

And if it has been, could you try removing all libx*.so files from the AppImage and running it again?

[RainOrigami]

I have extracted the AppImage and found the following matches:

./usr/lib/libxkbcommon.so.0
./usr/share/doc/libxkbcommon0
./usr/share/doc/libxkbcommon0/copyright

No occurence of libxkbcommon-x11.so.0.
There are also no specific libx*.so files but I found a bunch that may match?

./usr/lib/libxcb-xfixes.so.0
./usr/lib/libxcb-glx.so.0
./usr/lib/libxcb-icccm.so.4
./usr/lib/libxcb-sync.so.1
./usr/lib/libxshmfence.so.1
./usr/lib/libxcb-util.so.1
./usr/lib/libxcb-image.so.0
./usr/lib/libxkbcommon.so.0
./usr/lib/libxcb-render-util.so.0
./usr/lib/libxcb-present.so.0
./usr/lib/libxcb-shm.so.0
./usr/lib/libxcb-render.so.0
./usr/lib/libxcb-xkb.so.1
./usr/lib/libxcb-xinerama.so.0
./usr/lib/libxcb-shape.so.0
./usr/lib/libxcb-keysyms.so.1

Removing those files and re-packing the AppImage has indeed worked. Replacing the original AppImage with the patched one works for running it through Steam and it now also autostarts with SteamVR as intended.

Thanks for your help!

[username223]

Yes, libx*.so was intended to be understood as a wildcard for all files that started with libx and ended with .so. :)

Be aware that this "fix" will only last until Steam updates or redownloads the original files. The root cause is not really solvable from our side since it has to do with the specific files packaged in the AppImage vs installed locally, of which there are thousands of possibilities.

It might make more sense to use the AUR version if that also works since it is also officially supported and doesn't run afoul of random dependency version issues.

It might make more sense to use the AUR version if that also works since it is also officially supported and doesn't run afoul of random dependency version issues.

Any idea how I would need to setup SteamVR to make it automatically start and exit the AUR version like you can with the Steam version (eg. in SteamVR settings autostart or as startup parameter)? Sorry if this is offtopic for this issue but that is the only reason why I wouldn't want to use the AUR version over the Steam version.

[username223]

I wouldn't know, sorry. I was actually under the impression that autostart was generally just broken on Linux.

The easiest thing to do would probably just be to create a script to extract the AppImage, delete the files and then reassemble.
