Hello Damien,
I tried to insert the t490 config
but all that works at the moment is nixos-rebuild boot and build (not switch)
https://discourse.nixos.org/t/nixos-rebuild-switch-vs-build-vs-boot-networkmanager-wait-online-service-fails/7720
- I guess that the boot part has changed but don’t know how to proof that
At the moment with some other adjustments regarding the kernel and libinput parameter the freezing is gone in its dramatic way.
