Retroarch crash using vulkan [SOLVED]


Hey all,

I have a issue where vulkan will crash/force close retroarch using any core (gl works perfectly fine), I am able to use vulkan fine in standalone dolphin emulator. I’m getting an odd wayland error running retroarch in verbose “[ERROR] [Wayland]: Failed to connect to Wayland server.”. Any help would be greatly appreciated. Let me know if you need any other logs/info.

The wayland thing is a red herring. I believe the ‘X Error of failed request’ bit is the real issue, though I don’t know what it’s all about.


Application can not detect nvidia’s vulkan driver, just export VK_ICD_FILENAMES environment variable to proper ICD file. In my case: VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json


I even have the same issue on Ubuntu 18.04 LTS. Is the builds different from their app store than the ones from Libretro repository? (The difference is that I can install cores in Retroarch when installed from the app store, while the ones in Libretro repository, you have to install cores from repository.)

I switched to Vulkan from the settings to see how it performs. My GPU is Radeon RX 570 8GB, using Mesa 18.2.8 from the main repository and tried finding few others. RADV seems to be installed. I even installed libvulkan-dev since I thought that would fix the issue for starting Retroarch with Vulkan, but it didn’t.


Vulkan doesn’t work with the snap package currently. I’m trying to figure out why but haven’t really gotten anywhere with it, unfortunately.


Thanks, I’m not sure how mark this as solved. But I believe my issue was I didn’t close and relaunch retroatch after switching to Vulkan driver.
