+<WRAP info>
+**NOTE:**  The actual driver files, can be located in various directories.
+Although **/usr/share/vulkan/icd.d/** and **/etc/vulkan/icd.d/** are the most commonly used paths, the Vulkan loader looks in all the following locations:
+<code>
+/etc/vulkan/icd.d
+/usr/local/etc/vulkan/icd.d
+/usr/local/share/vulkan/icd.d
+/usr/share/vulkan/icd.d

+===== Reenable the ICD based loading approach =====
+Alternatively to the above.
+<code bash>
+export DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1
+</code>
+<WRAP info>
+**NOTE:**  When **DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1**, you can choose your preferred Vulkan driver by setting the environment variable **VK_ICD_FILENAMES**.
+  * For example, running Steam with the RADV driver is done by:
+<code bash>
+VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json steam
+</code>
+  * To avoid crashes with 32-bit games, it is possible to assign the 32-bit variant and the 64-bit variant to the environment variable.
