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 11:11:04 -04:00			`boot.kernelParams = [`
