vulkaninfo fails with VK_ERROR_INCOMPATIBLE_DRIVER since 17.10

[Christopher Crouzet]

I'm using a Dell XPS 9560 with a Geforce 1050.

Back on 17.04 (libvulkan-dev-1.0.42.0, nvidia-375) I could run vulkaninfo and my own Vulkan applications without a problem but, after switching to 17.10 (libvulkan-dev-1.0.61.1, nvidia-384), running vulkaninfo now results in the error attached. In other words, I cannot run any Vulkan-based application anymore.

I have tried using Vulkan's SDK 1.0.42.2 from LunarG's website without success.

I have been tempted to try rolling back to nvidia-375 but not being so familiar with Linux, I am a bit worried that things might go wrong.

Here are some further investigations, if it can help:

- I have upgraded from 17.04 to 17.10 rather than doing a fresh install
- by default, the file /usr/share/vulkan/icd.d/nvidia_icd.json has its ICD's library_path set to libGL.so.1. If I change the value to libGLX_nvidia.so.0 instead, I can run vulkaninfo again without any problem
- `echo $XDG_SESSION_TYPE` returns x11. At the login screen, when clicking the cogwheel icon, I am not given the choice to use Wayland so I am using 'Gnome on Xorg' instead

Status changed to 'Confirmed' because the bug affects multiple users.

I see same problem running Ubuntu 16.04 with Geforce GTX 1060 card, that is vulkan programs failing with VK_ERROR_INCOMPATIBLE_DRIVER.

Attaching output of the vulkaninfo just in case.

Replacing libGL.so.1 with libGLX_nvidia.so.0 in nvidia_icd.json also solves the issue for me.
