For some time I'm getting this segfault in dmesg each time a game is exiting :

[30425.697110] wineserver[29286]: segfault at 0 ip 00007f72418ad6f4 sp 00007ffdde826740 error 4 in libnvidia-glvkspirv.so.535.146.02[7f7240800000+2038000] likely on CPU 1 (core 1, socket 0) [30425.697124] Code: 00 00 00 00 00 90 53 48 8b 1f 48 89 df e8 74 38 0d ff 48 89 df 5b e9 2b 39 0d ff 66 2e 0f 1f 84 00 00 00 00 00 90 48 83 ec 08 <48> 8b 3f e8 94 3a 0d ff 85 c0 0f 94 c0 48 83 c4 08 c3 66 2e 0f 1f

I think it starts happening several weeks ago after a nvidia-drivers update or a steam update, I'm not sure.

I found a thread on nvidia forums ⁽¹⁾. This leads me to another thread on archlinux forums ⁽²⁾.

In the steam.desktop file provided by games-util/steam-launcher, if I set :

PrefersNonDefaultGPU=false

instead of :

PrefersNonDefaultGPU=true

the segfault does not happen anymore.

Isn't that just switching to your non-NVIDIA GPU? That doesn't seem like a good change to make in general. I don't use NVIDIA at all though, so it's hard for me to make a call on this.

I don't know. All that I know Is that a segfault is never a good sign, and this one is spamming my log files.

The second GPU is an integrated Intel, but is never used, and the intel driver is not even loaded, I do not see how steam can pretend to use it.

There is an opened bug upstream on this subject : https://github.com/ValveSoftware/steam-for-linux/issues/9940

They seem to agree that removing (or changing) the key is not a good idea at the moment. I'd ping them on that issue as it seems to have stalled.

I added a comment on upstream bug.

In the meantime, I enabled the Intel iGPU, and I'm now using NVIDIA's PRIME render offload for steam and games. Everything is working fine, but the segfault is still there.

Without any explanation the segfault disappeared two weeks ago. Still the same version of nvidia-drivers, and steam was updated one week after the segfault disappeared. ?
