alacritty: Alacritty v0.3.0-rc2 does not start (Error creating GL context)

same thing on pop os after upgrading some packages (don’t remember which ones)

alacritty version:

[~]$ alacritty --version                                                                                                                                                                                                                                                                                                     
alacritty 0.4.3

EDIT: after reading this thread I realized nvidia driver was upgraded. A reboot solved the issue

You need GL wrapper for OpenGL stuff with nix outside of nixos. Consult nix docs wrt that.

@ojsl1 You probably just need to reboot after a driver update. That’s just something you need to do with certain drivers.

This issue happens to me on every upgrade of some graphic specific package on my system, although I didn’t determine which one it is yet.

As alacritty leverages GPU capabilities, it is likely some cuda or nvidia package upgrade… Today I upgraded the below listed packages and had to restart the system for alacritty to start again, after the above mentioned error Error creating GL context; Received multiple errors. Errors: [OsError("eglInitialize failed"), OsError("GL context creation failed")] appeared.

I will come back after the next breaking upgrade and likely narrow down the involved packages with an intersection.

@Bad3r me too on Ubuntu.

I just encountered this issue on Arch Linux 5.7.5-arch1-1

Sounds like it would be beneficial to wait for the next glutin release before releasing 0.3. Thanks for looking into this.
