Fullscreen support on ARM Linux (Ubuntu)

[tl8roy]

I am using Conrod with the Glium/Glutin backend.

When I run in Windows, the fullscreen mode works fine. When I try in Linux, I get the following backtrace:

gumstix@ubuntu:~$ RUST_BACKTRACE=1 ./proto_one
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: BackendCreationError(OsError("Could not find a suitable graphics mode"))', /buildslave/rust-buildbot/slave/stable-dist-rustc-cross-host-linux/build/src/libcore/result.rs:799

This is the code used to build the window: // Build the window. let monitor = glium::glutin::get_primary_monitor(); let display = glium::glutin::WindowBuilder::new() .with_vsync() .with_dimensions(WIDTH, HEIGHT) .with_fullscreen(monitor) .with_decorations(false) .with_srgb(Some(false)) .with_title("Conrod with glium!") .build_glium() .unwrap();

Removing .with_dimensions(WIDTH, HEIGHT) appears to solve the issue.

Is the width and height you request a fullscreen resolution supported by your driver?

I has been a while since I checked this, but that certainly seems like it could be the problem.

We were having resolution issues, so I may have spec on higher than the screen can take.

This issue has likely been fixed via tomaka/winit#270.
