I have a question about STR.
There are three commands can trigger STR at console mode, powersave u, echo mem > /sys/power/state and echo 3 > /proc/acpi/sleep.
When I use the echo mem > ..." and "echo 3 > ... to trigger STR that will cause the system (SUSE 10.1 SP1) enter standby or shutdown after resume but powersave u is working fine.
So, the question is what the difference between these commands?
