Winit Error when running Example on Ubuntu 19.04

[cetra3]

Getting the following error when trying to run cargo run --example tour on my Ubuntu 19.04 lappy.

[2019-11-25T23:31:50Z ERROR winit::platform_impl::platform] X11 error: XError {
        description: "BadDrawable (invalid Pixmap or Window parameter)",
        error_code: 9,

        minor_code: 4,
    }

Thanks for the report!

I found rust-windowing/winit#748 describing the same issue.

It seems the cause may be that your environment does not support Vulkan. You could try running the vkcube example to confirm this.

I am working on an alternative for rendering that should fix some of these issues. I hope I can share something soon!

Ah right, I'm surprised since I'm using the proprietary nvidia drivers. I assume there is a few more packages I would have to install. I'll have a play around and see if I can get it to work

Ok, looks like it's a nvidia Optimus silly issue. It tries to load the intel driver for some reason.

For posterity here are the steps I took to diagnose:

• Installed vulkan-tools with sudo apt install vulkan-tools
• Ran vkcube - noticed it turned out black
• Removed the file at /usr/share/vulkan/icd.d/intel_icd.x86_64.json
• Ran vkcube again - noticed it worked.

Now the tour works too!

Removing the json helped. I had this problem together with this lines:
