the code on github SaschaWillems/Vulkan runs smoothly on WIN10 with a VERY old GPU GT730, but when i wanna run it on ubuntu, i encounter a lot of problems. here is a breaf of my system:
Operating System | Ubuntu 16.04.5 LTS
Graphics Card | GeForce GTX 1080
Driver | 430.50
SDK Version | 1.1.121.0
but when i run Vulkan, it will return ERROR_INITIALIZATION_FAILED.
so i follow the guide of "Getting Started with the Vulkan SDK" on the lunarg website, i install the vulkan-sdk first:
wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-xenial.list http://packages.lunarg.com/vulkan/lunarg-vulkan-xenial.list
sudo apt update
sudo apt install vulkan-sdk
then i run vkvia as told, the return error shows "Vulkan failed to find a compatible driver", so i follow the doc and then find "Vulkan Graphics Driver Problems". the doc tells that there are possiblely 4 kind of reasons:
1. hardware not support Vulkan. but i found on nvidia website GEDORCE GTX 1080 is OK for vulkan1.1
2. driver not support Vulkan. but i found on nvidia website driver 430.50 is OK for vulkan1.1
3. no Vulkan driver with support for the OS. i am running on ubuntu 16.04.5 LTS,
4. driver failed to install properly. But i can use nvidia-smi to show the card, and i can run my other code on this GPU without VULKAN
if i run vulkaninfo, the error info is vulkaninfo.c:6155: failed with VK_ERROR_INITIALIZATION_FAILED
hope someone can help me! thanks!
