Re: Setting screen timeout period on 14.04 clients?

[David Groos]

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

Thanks Alkis!

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.

Hi John,

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


Thanks!

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



A desktop entry file to run the script (and appear in the
Preferences menu):
/usr/local/share/applications/power-mode-toggler.desktop

Hi John,

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

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.
