[SamuelTrew]

• Operating System: Ubuntu 20.04
• Revery Version: revery-ui/revery#625794e
• OCaml version: 4.9.0

• Native, Bytecode, or JS build: Native

• Link to github repo: Just revery-quick-start

• Steps to reproduce: follow their guide and run install, build and run

• Actual Result: black window appears

• Expected Result: should display a small program

• Additional Information: I installed the dependencies that it mentioned and the install and build steps run fine.
  I saw issue #807 but the linked oni issue seems to say it fixed it but that doesn't seem to have been brought over

• Search terms used: unable to create skia context, unable to create native interface, skia, canvas context

I get the exact same error with revery-quick-start on Ubuntu 20.04.

Usually, this is due to not having the X11 headers / libraries installed prior to building esy-sdl2 - the CheckX11 check in the ./configure script fails: https://github.com/revery-ui/esy-sdl2/blob/1cd3d4ffd9220b02fe6c27a08c8e4e2283dfee20/configure.ac#L1602 - and so there is no video device baked into the build of SDL.

You can fix it by the following:

• Ensure you've installed the xorg-dev package to get all the X11 libraries / development headers
• Clear the esy cache - rm -rf ~/.esy
• Run a git clean -dxf in the project directory, ie: ~/revery-quick-start, ~/oni2, etc. (WARNING: this will remove any unsaved changes)
• Run esy install & esy build

Unfortunately most of the dependencies will have to rebuild, because this necessitates rebuilding SDL2 to get the proper headers / enable X11 video, which is a pretty core dependency.

Installing xorg-dev, clearing the esy cache and rebuilding the project worked for me!

That worked perfectly, thank you!
