I'm trying to get started doing some vulkan programming and am having difficulties with the development environment. While trying to troubleshoot I encountered some issues that might illuminate my configuration issues. How do I correct these development environment issues to make vkcube work?

Apparently the 32 bit errors for vulkaninfo are just vulkan trying all of the available drivers. See: Vulkaninfo output errors on Nvidia
Trying the command in the warning doesn't help (as suggested by : https://www.reddit.com/r/wine_gaming/comments/m7ircp/mesaintel_warning_performance_support_disabled/ ).
Tried https://github.com/SaschaWillems/Vulkan as a sanity test to see if maybe vulkan worked but vkcube didn't. Still a black screen. Likely a driver configuration error.
Very minimal change, tried downloading the newest vulkan version.
https://vulkan.lunarg.com/doc/sdk/1.2.189.0/linux/getting_started.html
Download, extract
source ~/vulkan/1.x.yy.z/setup-env.sh
vkcube works
I downloaded it to the applications folder and extracted it there. I then added the following lines to the end of my ~/.bashrc.
export VULKAN_SDK=~/applications/1.2.189.0/x86_64
export PATH=$VULKAN_SDK/bin:$PATH
export LD_LIBRARY_PATH=$VULKAN_SDK/lib:$LD_LIBRARY_PATH
export VK_LAYER_PATH=$VULKAN_SDK/etc/vulkan/explicit_layer.d
I was at this point still getting errors (or a blank screen) when trying to run the examples from...
git clone https://github.com/SaschaWillems/Vulkan.git
cd Vulkan
python download_assets.py
cmake CMakeLists.txt
make
cd bin
./triangle
Everything worked after purging the mesa-vulkan-drivers.
sudo apt-get purge --auto-remove mesa-vulkan-drivers
restart, and try ./triangle again (worked)
As a sanity check,I commented out the ~/.bashrc lines I added previously, then repeated the prior clone steps and everything worked.
