When I enter
sudo pm-hibernate in a terminal, it only turns the screen off for a small moment and immediately turns it on and then terminal goes to another blank line. (
pm-hibernatewill be finished)
Also it should noted that execution of
sudo pm-is-supported has no output.
When I was using Ubuntu 14.04 and 14.10, this command was working fine. But in 15.04 it has stopped working.
- I'm currently using Ubuntu 15.04 - 64bit
pm-suspend-hybriddoes NOT work. (exactly same effect of hibernate)
- I've enough disk space to save system state.
