NixOS on Dell 7490

The well-known kernel options i915.enable_dc=0 and intel_idle.max_cstate=1 are still helpful with my latest installation of NixOS 24.5 on this device.

Linux on Dell 7490

Don’t miss to add kernel options i915.enable_dc=0 and intel_idle.max_cstate=1, if you want to run a modern arch linux on your Dell Latitude 7490.

Docker Cleanup

Recent versions of the Docker CLI support the prune option in different flavors to keep the system clean.

But I also want to bring some risks into focus.
