libEGL warning: DRI2: failed to authenticate

[petr-tik]

Built from 6f66b97, run ./src/emacs -Q got these errors

configured and built like this

./autogen.sh && ./configure --with-nativecomp --with-webrender
make -j 16

Full backtrace when running emacs - no GUI opens. Without web-render it works fine.

rfbt ./src/emacs -Q

The readme says

If you get "Couldn't find any available vsync extension" runtime panic, enabling 3D acceleration will fixes it.

so I was wondering how I can enable that.

[petr-tik]

also, what's the best way to start emacs under gdb or rust-gdb? I seem to load the main executable successfully, but fail to set a breakpoint in a extern'ed rust method with a DWARF error

The rust method is draw_glyph_string

@petr-tik I've encourted that error while running in virtualBox without 3D acceleration enabled. I enabled it via this menu:

If you are not using virtualBox, or a VM in general, you may need to look into your system configuration to confirm that you can run openGL applications.

[petr-tik]

Using this tutorial checked if i have 3D acceleration and it seems that I do.

It's glutin's issue, we can't fix it in this project directly.

rust-windowing/glutin#1262
alacritty/alacritty#4599

[petr-tik]

ok, the alacritty issue might give space to reproduce, as I have been running alacritty on my system without any issues for ages.

currently running

alacritty --version
alacritty 0.6.0-dev (0dfd860)

Let's build v0.7.1 and see if it has the same problem

The GUI starts despite the error, the config errors are irrelevant here.

It seem that glutin is the main difference. I can post the diff of Cargo.lock - if you are interested?
