LinuxQuestions.org - [SOLVED] Disable KDE4 screensaver while watching a movie

Disable KDE4 screensaver while watching a movie

My KDE screen saver is set for 15 minutes and this bash script is in my Autostart for KDE4.

It simulates user activity every 10 minutes vice disable/enable the screensaver.

It uses a single line of program names separated by spaces. Enjoy. ;)

Nice script!

But I'm replying on the subject of the copyrights.
I've done a similar set of scripts (with the help of äxl) and posted it here: http://www.linuxquestions.org/questi...ns-4175468270/ (current scripts at post #5).
They're meant to be used with XFCE, not KDE and intended to prevent the computer from suspending (not blanking the screen, for my purposes kepping the screensaver active is actually a good thing). But the rational is basically the same as for your script.

I can still work a lot on it and one thing I was thinking about is the way it checks for active programs that should prevent the computer from suspending. I'm doing it through an "if ( pgrep -l program1 ) || ( pgrep -l program2 ) || ..." condition but your way seems much more efficient.

So my question is: can I just take that part of your script (the "programs="prog1 prog2" + modified "for" loop) and add a modified "copyright" notice after what I currently have, such as (proposed addition in bold):

Code:

# Script suggested by user "äxl" at LinuxQuestions.org in reply to a question of mine (JDAckle):

# « XFCE (or related) Power Management "Inactivity" Settings/Exceptions »

# http://www.linuxquestions.org/questions/linux-desktop-74/xfce-or-related-power-management-inactivity-settings-exceptions-4175468270/

# 02/07/2013 to 07/07/2013

# Process-running check modified according to the way Jack S. Lai coded his own  "Disable KDE4 screensaver while watching a movie" script, posted at http://www.linuxquestions.org/questions/linux-desktop-74/disable-kde4-screensaver-while-watching-a-movie-4175471090/#post4997687 (27/07/2013, 06:06 GMT

Thank you kindly,

You can take any PART of the script as needed w/out copyright inclusion. The script as a whole is the only thing copyrightable. But I do appreciate the mention :)

Thank you!
Will be glad to make the mention! ;)

EDIT: Done!

v1.1 10/31/13 - added "--sort -pcpu" to make the search quicker.
