Rasbian Stretch screensaver disable

[Kimzer]

Hiyaaaaa. Having problems disabling the screensaver.
Ive tried countless guides and none seem to work.
Tried;

Add these lines to /etc/xdg/lxsession/LXDE/autostart (LXDE-PI also)
@xset s noblank
@xset s off
@xset -dpms

Tried installing screensaver software and disabling it there. But all to no use.
How do we do this properly in stretch?

this Debian Stretch: deactivate screen blanking

says

add those lines to

/home/pi/.config/lxsession/LXDE-pi/autostart 

note that is a file that is USER based…

I have done that, does not work :s

Is there a different method if ive changed to the opengl driver instead?

Hi,

maybe you have the same problem as me (and it’s not the screensaver).

In /var/log/syslog i found this messages:

Jun 13 07:12:41 raspberrypi kernel: [ 3057.339364] Out of memory: Kill process 1070 (electron) score 576 or sacrifice child
Jun 13 07:12:41 raspberrypi kernel: [ 3057.339426] Killed process 1070 (electron) total-vm:673580kB, anon-rss:59472kB, file-rss:0kB, shmem-rss:214908kB
Jun 13 07:12:41 raspberrypi kernel: [ 3057.373292] oom_reaper: reaped process 1070 (electron), now anon-rss:0kB, file-rss:0kB, shmem-rss:215056kB

For me it looks like electron has crashed.

After using google I’ve found a hint with other processes to change the value of vm.min_free_kbytes.
You can find it in /etc/sysctl.d/98-rpi.conf.

I’ved change the value to

vm.min_free_kbytes = 1024

After this there is no more blank screen anymore.
