bug#63514: alacritty>=0.12.0 does not work with Wayland

Hi Efraim,

since the upgrade from alacritty 0.9 to 0.12 it does not work any more
with the DISPLAY environment variable unset (i.e. without xwayland). The
error message is:

thread 'main' panicked at 'Failed to initialize any backend! Wayland status: NoWaylandLib X11 status: XOpenDisplayFailed', /tmp/guix-build-alacritty-0.12.0.drv-0/source/guix-vendor/rust-winit-0.28.3.tar.gz/src/platform_impl/linux/mod.rs:757:9

Could you have a look?

Thanks,
Lars

That's certainly annoying. I'll take a look and see if I can find a good
way to fix that.

easy reproducer: 'DISPLAY="" alacritty' gives the same error.

Do you know if the X11 error is also a problem?

Hi,

> easy reproducer: 'DISPLAY="" alacritty' gives the same error.

that’s exactly what I used under Wayland, otherwise it’ll fall back
to XWayland with ugly font rendering (because of my hidpi monitor).

> Do you know if the X11 error is also a problem?

Not sure what you mean. As I wrote it works with XWayland, so I’m
guessing X11 is not broken.

Thank you,
Lars

PS: What *is* entirely broken is swaylock, which also got updated
recently:

wl_registry@2: error 0: invalid version for global wl_output (39): have 3, wanted 4

I parsed the error like this:

(ins)efraim@3900XT ~$ DISPLAY="" alacritty
thread 'main' panicked at 'Failed to initialize any backend! Wayland status: NoWaylandLib X11 status: XOpenDisplayFailed', /tmp/guix-build-alacritty-0.12.0.drv-0/source/guix-vendor/rust-winit-0.28.3.tar.gz/src/platform_impl/linux/mod.rs:757:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace


(ins)efraim@3900XT ~$ DISPLAY="" alacritty
thread 'main' panicked at 'Failed to initialize any backend! Wayland status: NoWaylandLib
(no wayland library found!)

X11 status: XOpenDisplayFailed', /tmp/guix-build-alacritty-0.12.0.drv-0/source/guix-vendor/rust-winit-0.28.3.tar.gz/src/platform_impl/linux/mod.rs:757:9
(something something XOpenDislay failed! with that source location)

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This should now be fixed, feel free to re-open if its still not working
for you.
