Why is my OpenBSD desktop is shutting down suddenly ?

rhtoras

I am on Openbsd 7.8 and while i am working the computer is shutting down after 4 minutes. When i press the power button it returns where i was. It is annoying and this happens for the first time (i have used openbsd in the past without issues). This is a fresh installation.
Now take a look on my .xsession to see what's going on...
I tried with the xset command but nothing worked. I have to mention i am on fvwm1.

export lang=en_US.TF-8

export ENV=$HOME/.kshrc

#xrdb -merge $HOME/.Xresources

xset b off

ulimit -Sc 0

#xidle &

xsetroot -solid darkslategray

LANG= xclock -strftime "%a %e %b %Y %H:%M" &

xset s off
xset s noblank
xset -dpms

#redshift -p -o 3500 &
exec fvwm

This usually happens every 4-5 minutes again and again.
Any help is appreciated.

Is the computer actually shutting down, the monitor blanking, or something else?

If the computer is actually shutting down and coming back in the same state as it left, I'd suspect apmd is misconfigured and sending you into hibernation - check the apmd_flags in /etc/rc.conf.local. You would also see a message about unhibernating during boot.

If the monitor is blanking, check the monitor's settings through the monitor's built-in menu - the buttons will be different on different models, but usually there are power-saving settings and light/motion sensors, check any timers and automatic dimming settings.

Guys i solved the problem. Today i reinstalled openbsd and made an update to 7,9 version. I did the same procedure and now i am on fvwm 1. What i did is the following...

Create a sysctl.conf inside /etc/ with the following: `kern.shminfo.shmall=6291456
kern.shminfo.shmmax=999999999
kern.shminfo.shmmni=2048

kern.shminfo.shmseg=2048
kern.seminfo.semmns=4096
kern.seminfo.semmni=1024

kern.maxproc=3250
kern.maxfiles=8192
hw.smt=1
machdep.allowaperture=1

kern.audio.record=1
kern.video.record=1

net.inet.udp.recvspace=262144
net.inet.udp.sendspace=262144
net.inet.icmp.errppslimit=1000`

Then using vi editor i just typed: :%s/rw,/rw,softdep,noatime,/g inside fstab

Installed pico editor for faster results pkg_add pico

I also add my user to the following groups: usermod -L staff user (operator and wheel as well).

Enabled apmd (i am using a hp prodesk) with the following commands:
rcctl enable apmd rcctl set apmd flags -A rcctl start apmd

Since i was using su - i switched to doas editing the /etc/doas.conf
Inside this file i add: permit nopass keepenv :wheel
Lastly i fixed my sound: sndioctl output.level=1

Now my computer won't switch off suddenly.

I have to add an .Xsession file and install fvwm3 with some configs i found on the net.

Any suggestions on what to do next are wellcome.
