Description
After switching to using the flake to get 0.7.0 every time i try to lock my pc using hyprlock, it segfaults. I've included the segfault in the attachments below.
The sourced config files in my config, are purely themes - No other configuration is being set in them.
I'm using the repository flake to overwrite the home-manager package.
How to reproduce
- Use latest version of hyprlock flake.
- Try to lock the screen
Crash reports, logs, images, videos
After setting the flake to follow my own nixpkgs, it works without segfaulting. As i don't know wether or not it should work regardless of following the stable nixpkgs, i'm leaving the issue open for now.
Yeah so this is a known problem that people run into quite frequently on nixos.
We use something called gbm, to allocate a buffer for the screencopy frame and that requrires hyprlock using the same MESA version as the compositor.
That's why overriding the nixpkgs input fixes it.
I would love to detect this version mismatch in hyprlock and give the use a proper error for it, but so far I haven't found a good way to do that.
I think we can leave this issue open for now until we find a way to detect it.
