[SOLVED] Retroarch not launching anymore.

Hello, I don't know which update did this, or when, but retroarch used to work fine on my system and now trying to launch it does absolutely nothing. I know that version 1.7.8.4-1 wasn't working for sure, and this morning I updated retroarch to 1.7.9.2-1 hoping that it would fix it, but no luck.

When launching it from the command line, I get this output:

charlesg-laptop:~

Anyone knows what's up with that? Thanks!

Re: [SOLVED] Retroarch not launching anymore.

Haswell/Broadwell level CPUs have a known quite breaking mesa bug, is this the only thing you are noticing issues with? See the following thread: https://bbs.archlinux.org/viewtopic.php?id=249639

Re: [SOLVED] Retroarch not launching anymore.

My thoughts were different that were V1del's  I was wondering if you have recently changed to Wayland?

Yes I see no other issues. Also, it's been broken on my system for quite a while (let's say a month, and the issue you mentioned seems quite recent), but I was waiting for the next retroarch version before bringing that up.

No, I'm on Xorg and haven't switched to Wayland (just checked to make sure).

Thanks for the help!

Re: [SOLVED] Retroarch not launching anymore.

My thoughts are different from both of the above...

I'm experiencing a bug with a recent vulkan update, as posted here: https://bbs.archlinux.org/viewtopic.php?id=249696

I see you are using vulkan in retroarch. If you change your display driver from "vulkan" to "gl" does it work?

Re: [SOLVED] Retroarch not launching anymore.

Post the coredump, and your retroarch.cfg , retroarch doesn't attempt to utilise a xorg backend. Thrown in

glxinfo -B #Needs mesa-demos

while we are at it.

Yes it does work! Never touched that cfg file before though, so I wonder why it previously worked. Also not sure why retroarch doesn't automatically detect available drivers.

Problem solved, Thanks a lot!
