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.
