[mitchmindtree]

@bitbegin does #1032 fix this for you?

By "virtual win7" do you mean an instance of windows 7 run in a virtual machine like VirtualBox? Are you sure that your VM supports OpenGL?

[bitbegin]

how do i know it has installed OpenGL?

this crate only support OpenGL backend?

[daboross]

@bitbegin could you try removing the with_multisampling line in the window creation in example you're running - or try the newly updated example after #1032 was merged?

I think this is/was the same issue as https://github.com/PistonDevelopers/conrod/issues/1018.

[bitbegin]

@daboross i will test it tomorrow

[mitchmindtree]

@bitbegin conrod can be used with any kind of graphical backend, however it provides some helper functionality that reduces some of the boilerplate involved with a couple particular backends via cargo features. Most of the examples use the glium backend feature which is a pure-rust OpenGL library, which means they require OpenGL to be installed. One of the examples uses a piston backend (which happens to ouse OpenGL) and another uses gfx (though it's buggy and incomplete and also uses gfx's OpenGL backend).

[bitbegin]

removing the with_multisampling code or changing sample rate to 4 both not work.

My display driver is citrix.

The OpenGL version is 1.1.0 (1.20 for ext).

I have the same error message running the command cargo run --release --feature "winit glium" --example text I'm using VMware Workstation 14 Player, Ubuntu Gnome 64 16.04 LTS, OpenGL version 3.0 Mesa 17.2.8. Here the backtrace

Commenting the line 33 of text.rs fixed the issue. Specifically .with_multisampling(4)

Is the solution still to comment out some code? I do not even know which code it is running and where to look for with_multisampling in the example source code. Which example source code is run, when I do RUST_BACKTRACE=full cargo run --release --example all_winit_glium? text.rs does not appear in my backstrace.

EDIT 1: I was able to get the example to run, by grep-ing the whole examples source code and commenting out with_multisampling everywhere, where it was found in any .rs file. Not sure, why it is in the examples, if it is not working. OpenGL is installed, if that is part of the issue.

[hypixus]

I agree with @ZelphirKaltstahl here, multisampling seems to be not working properly on virtual machines. I'm on vmware hypervisor right now, running Linux Mint with full OpenGL Core 3.3 support yet this crate throws "GlutinCreationError(NoAvailablePixelFomat)". Problem is definetly elsewhere.
