Protecting my sleep
My another attempt to break the habit of being up until very late into the night and as such very tired the next day.
For years I thought of configuring my computer to suspend at around night time so I will be somehow forced to go to sleep. Well, the main problem with this was that I only thought about it and never actually did any research on this subject.
At normal times under my normal user I suspend my machine with elogind loginctl command and this works fine but there might be a problem with sessions and stuff around that which I refuse to work with. So I searched a bit and found out that there is nice system API to manage power state.
The system/kernel API consist of a file located at
When I try to print the content of this file it shows the currently available states (or values it accepts) which is my case are:
$ cat /sys/power/state freeze mem disk
And when I looked at the printed values I saw
mem option which is
probably what I want (I was lazy and did not look at any docs) to
suspend my machine into RAM. The power state can be changed by writing
desired state into
$ echo "mem" > /sys/power/state
Sure, you need to be root to do so, but so what? This is my machine and I can. Since I figured this out I put it into a file, set it executable and configured cron to start it at 23:00 from Sunday to Thursday like this.
0 23 * * 0-4 root /usr/scripts/suspend
And done, now I hope it can help me get my desired rest.
