Cemu: [Linux] Segmentation Fault when attempting to run Games

Cemu Experimental Version (Compiled) Commit Hash: dd1cb1c

OS -> Ubuntu 22.04.1 LTS GPU -> Intel HD Graphics 5500 (rev 09) CPU -> Intel i5-5300U (4) @ 2.900GHz

I’ve tried playing Super mario Bros for wii U and Mario Kart 8 in the cemu gamelist menu, but the application crashes and outputs:

Segmentation fault!
Error: signal 11:
./bin/Cemu_relwithdebinfo(handlerDumpingSignal(int)+65) [0x5586ab02e355]
/lib/x86_64-linux-gnu/libc.so.6(+0x42520) [0x7ff1381b4520]

Same issue on the lastest linux mint with Minecraft on load. Switch to opengl didn’t change anything.

@hstr0100 Glad it worked!

Curious that it was already set to “0” as that is NOT the default.

Also it resets on reboot, unless you have set it in your boot commands to apply at boot time, or repackage your initramfs with the option set.

It’s quite simply because I have a sysctl.d rule set for it already from a different issue, Ryujinx - the switch emulator, had literally half the performance of Yuzu on my system, so flipping that sysctl option to zero was one of the options I tested also to no avail,

The mesa driver also spit out that message for Ryujinx the difference is that using Vulkan does not crash that emulator.

echo "dev.i915.perf_stream_paranoid=0" | sudo tee /etc/sysctl.d/98-i915.conf
