I am on an Ubuntu 16.04 64bit using an AMD radeon r9 390 gpu
Recently I had installed the "amd gpu-pro-17.10" driver and had Vulkan working, and I could play Dota 2 with better performance than in Windows.
But running World of Warcraft 7.3 I had a little low fps in raids.
I decided to try out the The mesa graphics driver with Gallium Nine support, which WineHQ recommends for WoW.
Important part!!!
I uninstalled "amd gpu-pro" driver.
Then I installed "oibaf graphics driver",
following this tutorial https://wiki.ixit.cz/d3d9_tutorial
Rebooted, and now Vulkan isn't working.
I can't really find any help to enable vulkan for this new graphics driver.

Take a look at these two files:
They should look something like:
/usr/share/vulkan/icd.d/radeon_icd.i686.json
/usr/share/vulkan/icd.d/radeon_icd.x86_64.json
If not you can modify them for a quickfix, and please report as a packaging bug if this fixes your issue.
I don't own an AMD card, but spoke with a kind soul to find out the proper library should be as this is a known issue with some nvidia packages already.
