lenovo/thinkpad/x260: i915.enable_psr=0 parameter The video driver causes short freezes from time to time, especially if an external monitor is attached. Adding the i915.enable_psr=0 kernel parameter mitigates those freezes. This is a known problem for the X260, as mentioned in the Arch Wiki. It occurred mainly after switching to kernel version five. 2020-10-31 15:11:04 +00:00			`boot.kernelParams = [`

lenovo/thinkpad/x260: use services.tlp.settings With switching from NixOS 20.03 to 20.09, the services.tlp.extraConfig option became deprecated and was replaced by services.tlp.settings. The ThinkPad X260 is only device within nixos-hardware which makes use of this configuration. 2020-10-31 14:59:40 +00:00			`services.tlp.settings = {`
