[Isaac install]nvidia driver's location

Isaac 官網上有提到要自行增加環境變數，讓unity可以抓到nv driver

在~/.bashrc最後新增

export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json

但實際去找/usr/share/vulkan/icd.d/資料夾找不到nvidia_icd.json

後還發現在我的NB上是在/etc/vulkan/icd.d/nvidia_icd.json

實務上可以先updatedb後去locate nvidia_icd.json
