To be precise With kernel 5.4.0-14-generic "echo disk > /sys/power/state" does not seem to spend time on saving memory to disk like s2disk does , but laptop switches off (I assume it hibernates) and resume will not pick up where I left it. It starts normally. With kernels linux-image-unsigned-5.5.6-050506-generic and linux-image-unsigned-5.6.0-050600rc3-generic . The actual commands s2disk and "echo disk > /sys/power/state" return immediately as if something was wrong during memory saving. Laptop does not switches off.
