Basically .kde/share/config has some rc files that control screen saver power management of monitor - upon update krunner needs to be restarted
(this is all done via automated script below which runs on crontab and disables - screensaver powermanagement whilst u watch listen to audio)
You can modify as you like
I need to make a new version so it only stops locking screen for amarok this way I can still use remote control to control sound without having to enter password but I don't mind screen saver - for films it can remain in this current script so the new script would be a different if loop for amarok and films would remain as they are...

back to script...


As a default setup i preusme powerdevil and kscreensaver are used:

feel free to remove config for krandtray and kpowersave they are there just incase you use different methods to control PM.

in your home folder open a shell
mkdir scripts
cd scripts
first do
env|grep DISPLAY (ensure the display number matches first line of script also update username to match your username and make sure home folder paths etc match up to your setup)
then

vi watching-film.sh
esc i [ insert mode copy paste below into it then :wq then chmod 755 ./watching-films.sh and follow crontab entry below]

add above crontab entry and screen saver is now controlled via this script

thanks

I kind of wish I had not continued this in shell and written it in perl.

anyways this is the updated version..

There is a section for audio then a section for video

The reason for the devision is I don't mind screen saver for audio - it means one extra press on remote control to get screen back - but if it locks it requires a password to allow remote to control again. this can be annoying if you have it set to every minute.

Anyways feel free again to add or alter things you wish to disable for each mode I have removed kpowersave and krand since as standard its powerdevil and kscreensaver.

Here is updated script - only change is audio stuff still screen saver but no locks again update the media list to other applications or remove if you only wish actions for specific apps.
