[Linux] Window creation fails on platforms without VSYNC extensions
The pull request https://github.com/rust-windowing/glutin/pull/1253 prevents Glutin from creating windowed contexts on systems that do not have vsync extensions. It fails even if vsync is set to false.
CreationErrors([NoAvailablePixelFormat, OsError("Couldn't find any available vsync extension")])
In my opinion instead of throwing an error at mod.rs#L459 we shall ignore vsync if there are no available extensions.
Here is an example of such limited system:

0.23 is switching over this to an option. I think it would be improper to just ignore the requested vsync. I wouldn't mind if something similar was added to 0.22.
This started happening to me as well. Can't use Alacritty anymore. Is there a workaround?
I fixed this issue by reverting the oibaf ppa
sudo ppa-purge ppa:oibaf/graphics-drivers
It's happening to me too. It happens not only on Linux but also on FreeBSD. What should I do? It looks like just disable vsync will do the trick, expect an update to fix this in a while.
