v0.91 - Touchscreen goes to screensaver regardless of setting 0

Freakadude · February 2019

Hi,

With the latest version i noticed that my touchscreen goes to screensaver after about 10 mintues. I had previously disabled screensaver by having a time limit set of zero. Now it seems regardless of this setting a screensaver is applied after a few minutes and i can't seem to turn it off.

Not a huge issue but it was not there in the last version.

Cheers

Ok, found reason. We have a new script for screensaver and that is not in sudoers list. Over ssh send
sudo echo "repetierserver ALL=NOPASSWD: /usr/local/Repetier-Setup/bin/screensaver" >> /etc/sudoers.d/repetierserver-perms

to fix. Then set timeout 0 and disable display should be disabled. You need to toggle if it is already. Then it will work.

Next update will fix it automatically.

When i send above command i get following permission denied response:

pi@RepetierServer:~ $ sudo echo repetierserver ALL=NOPASSWD: /usr/local/Repetier-Setup/bin/screensaver >> /etc/sudoers.d/repetierserver-perms

-bash: /etc/sudoers.d/repetierserver-perms: Permission denied

In your variant the quotes are missing!
sudo makes you root so you should have all permissions. You can also edit the file and add the line manually
sudo nano /etc/sudoers.d/repetierserver-perms
and add line
repetierserver ALL=NOPASSWD: /usr/local/Repetier-Setup/bin/screensaver

In my original try the quotes where there but same result. Not sure why they were gone from the version i pasted here. Regardless i now did the edit with nano and it seems to work now fine. Thanks!

Hi,

I'm having the same issues, regardless what timeout I set, the display goes dark after 10 minutes. I already checked what's stated above. I'm on version 0.93.1.

Thanks

Hello, I had the same problem, to get rid of it, I had to install a screen saver in the OS, then in the choosing disable in the menu.

Don't set time to 0. That will not help also it states it does. Fixed that for next release. Use the switch below and disable screensaver to call the disable function.

Sorry for not being clear in my report, but I have the time set to an hour, not 0. Anyway, let's wait for the next version

I see. That is then the dpms default timing taking over. Looks like this has changed in buster. The default there is 600 seconds so 10 minutes and does not get set in current screen saver script. Will be fixed in next image. But you can also just replace content of /usr/local/Repetier-Setup/bin/screensaver with

#!/bin/bash

# Implements commands
# screensaver on - Called when screensaver should activate
# screensaver off - Called when screensaver should be inactive
# screensaver config <0/1> <time> - Set time for screensaver. <0/1> enables/disable function.

export LC_ALL=C
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd $DIR
CMD=$1
P1=$2
P2=$3

case $CMD in
  on)
    # Add code to run on screensaver activation
    if [[ -e "/dev/backlight-1wire" ]]; then
        echo 0 > /dev/backlight-1wire
    fi
    ;;
  off)
    # Add code to run on screensaver deactivation
    if [[ -e "/dev/backlight-1wire" ]]; then
        echo 80 > /dev/backlight-1wire
    fi
    ;;
  config)
     export DISPLAY=:0
     if [[ "$P1" == "0" ]] ; then
        xset s off
        xset -dpms
        xset dpms 0 0 0
        xset s noblank
        xset s reset
        echo "Screensaver disabled"
     else
        xset s on
        xset +dpms
        xset dpms 0 0 $P2
        xset s blank
        xset s $P2
        echo "Screensaver enabled"
     fi
   ;;
esac

which is the source for next image screen saver script.
