Screensaver won't turn off. Autostart Chromium

Sat Aug 02, 2014 2:33 pm

Hello,

after i've tried to disable the screensaver with a lot of solutions found here in the forum and on other platforms, i can't figure out my problem.

After 20-30 Minutes i get the weird screensaver, shown in the pictures below.
I start the screen session with "startx" and i run chromium in kiosk mode via autostart in fullscreen mode with a preset website in the file /etc/xdg/lxsessions/LXDE/sutostart.
I've tried all this stuff:
  • Added the line setterm -blank 0 to /etc/rc.local
  • Installed x11-xserver-utils and editet ~/.xinitrc AND /etc/X11/xinit/xinitrc files. Added this:

    Code: Select all

    xset s off
    xset -dpms
    xset s noblank
    
  • Editet /etc/kbd/config and Changed the lines:

    Code: Select all

    BLANK_TIME=30 # changed to
    BLANK_TIME=0
    POWERDOWN_TIME=15 #changed to
    POWERDOWN_TIME=0
    
  • Editet /etc/lightdm/lightdm.conf and inserted:

    Code: Select all

    [SeatDefault]
    xserver-command=X -s 0 dpms
But nothing of this really helps. Even if i put this all together!
Can anyone of you figure out how to completely disable the screensaver?

Or is this a chromium screensaver??

I run debian wheezy on the latest version ...

I really need quick help ... We are showing important alerts of our fire department on this screen and it's really disadvantageous that the screen goes pixelated after 20 minutes.

Hi,

I'm using just about 50% of your settings (set just in /etc/xdg/lxsession/LXDE/autostart and /etc/lightdm/lightdm.conf) and the display shows expected content all the time. There was also not a single change done in chromium (just default page set).

Does your monitor thinks that it must be smart (have you tried with another monitor) ?
What action is required in order to see again the expected content ?

Try to perform proper testing of the next project, prior to production installation.

I don't think so. I will check it when i'm home. If thats the monitor screen saver, its a really ineffective one ...

I only need to press a key, even if that changes nothing on the Display.

Best whishes, Tim

Hi,

It's a PackardBell Viseo243D Monitor. I've tried it with other monitors and it's every time the same screen saver ....

I don't know what else i can do

Undo the settings except from the two files I listed earlier.

I had a similar issue where the @xset commands were not taking into consideration. I found out I was missing two packages, so I installed them like so and it worked:

Code: Select all

sudo apt-get install x11-xserver-utils unclutter
Try this :)
