Setting screen timeout period on 14.04 clients?

[David Groos]

Hi All,

I'm trying to change the settings (on lts.conf?) such that when I'm broadcasting an image/chart/presentation or whatever on student screens (thanks to epoptes) the screen doesn't require a student to move the mouse to keep the screen active. I searched this page: http://manpages.ubuntu.com/manpages/trusty/man5/lts.conf.5.html to no avail.

Thanks,

David G

I'm running Lubuntu and made a script to toggle a pseudo Presentation Mode.  As designed, each student would toggle the setting himself.

Note: The small package libnotify-bin must be installed to use notify-send.
Note: The Presentation Mode settings are not permanent; they expire with the session

#!/bin/bash
# /usr/local/share/applications/xset-mode.sh
# A script to toggle between Presentation and Normal mode and notify the user of the mode
STATUS_MONITOR=$(xset q | grep "DPMS is" | awk '{print $3}')

    if [ "$STATUS_MONITOR" == "Enabled" ]; then

       xset s off
       xset -dpms
       notify-send -t 5000 “The computer is now in Presentation Mode”

    else

       xset s on
       xset +dpms
       notify-send -t 5000 “The computer is now in Normal Mode”

    fi

Hi John,

I'll check this out on the weekend. Not sure what "Presentation mode" is in the context of ltsp?

Thanks!

That's just what I named the state produced by these settings.  It's what you would want if you were giving a presentation, playing a movie, etc. and didn't want the screen to blank.

File a bug report on epoptes so that we include that ability in some
newer version.

For LTSP, you can do that with X_BLANKING=0.

That looks super simple, will try on Fri. Also, will submit the bug report, yeah, seems like a handy feature.

Thanks Alkis!
