Hello, in my Lenovo Optimus laptop (Intel iGPU and Nvidia GPU) I’ve updated my nixpkgs flake input rev from 551c27677d66d635004f44784d10643edfaec6d to 23e89b7da85c3640bbc2173fe04f4bd114342367 and nixos-rebuild succesfully (after many interventions). Now, when I try to startx to start X, I get many errors (looks like it’s not using intel drivers for my intel iGPU and falling back to modesetting): (EE) unw_get_proc_name failed: no unwind info found [-10]. I’d be very thankful to anyone who have any ideas fixing it since it’s in a unusable state for me basically.
