Pi Zero

@Neokamikaze hi, what did you do to stop the screen from blanking? Having got the kweb and MM running perfectly I set this up to run without screen blanking an got the mirror in position… but it still blanks after about 10 mins+. The steps I took were:

Turn off the monitors energy saving mode.

I then edited ~/.config/lxsession/LXDE-pi/autostart and /etc/xdg/lxsession/LXDE-pi/autostart commented out the screensaver line and added:

@xset s off
@xset -dpms
@xset s noblank

Finally in /etc/kbd/config I set the following to:

BLANK_TIME=0
BLANK_DPMS=off
POWERDOWN_TIME=0

What am I missing here?

Hi @nigel-daniels, i don’t touch kweb configuration. I just add on “~/.config/lxsession/LXDE-pi/autostart” file this:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash

and in “/etc/xdg/lxsession/LXDE-pi/autostart” this:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
@xset s noblank
@xset s off
@xset -dpms

After for configure my display i change the configuration in “/boot/config.txt”.

@Neokamikaze HI thanks for the suggestion, I’ve ensured both my versions of these files match yours, but somewhere DPMS is being enabled… 10 mins in the screen blanks. I can see in the file /var/log/Xorg.0.log the following lines:

[ 81.864] (II) FBTURBO(0): enabled fbdev copyarea acceleration
[ 81.865] (==) FBTURBO(0): Backing store enabled
[ 81.875] (==) FBTURBO(0): DPMS enabled
[ 81.875] (II) FBTURBO(0): failed to enable hardware cursor

Something somewhere is setting DPMS up and for some reason the xset -dpms command is being skipped. I’ll try adding the set command to the start.sh and see if that forces the issue.

Hi @nigel-daniels, if you use jessie i think there is a problem with DPMS. There is a GUI package for configure this. If you want test install “xscreensaver” package

@Neokamikaze Thanks I’ll give that a shot. This is Jessy, and it sounds like the sort of problem I’m seeing.

Me thinks it will need to be in the morning now… gone midnight in my TZ so I’ll get screensaver on board and deal with pulling the mirror apart to get the minikbd plugged back in till then.

I’ll let you know how it works out.

@nigel-daniels sigh ok tried that rebooted into the GUI and used the screensaver config to switch off the screensaver. Then reconfigured the system to log into the CLI and use the start.sh to kick of X/Kweb… 10 mins later a black screen. I’m running out of locations to try using the set commends, I even added them to the start.sh.

So my promised input to the whole thing:
I gave up on kweb and using midori browser. It automaticly starts in fullscreen and kiosk mode. I have to put in a delay after “node serveronly” of 45s.

Bootup in console mode and add this in /etc/rc.local

sudo -u mirror /home/mirror/MagicMirror/serveronly

sleep 45s;

sudo -u mirror midori -e Fullscreen -a http://localhost:8080

and thats it. Works for me.

@darkeagl105 HI thanks for the update, I did end up recompiling Kweb which worked once I’d figured out I had to do that… I’m just now stuck figuring out how to stop my screen blanking after 10 mins! I think I’ve added the xset commands in about 5 locations and still nothing!

Getting an:
/home/pi/start.sh: line 4: xinit: command not found
where line 4 is:
xinit /usr/bin/kweb -KJE4 “http://localhost:8080”

any help appreciated. thank you in advance.

@nigel-daniels I realise this is really late, but I found a solution to my screen blanking on this site, at the bottom with “setterm -blank 0”.
