When vlc is running, the screen goes blank every 10 minutes. This requires to move the mouse or hit keyboard periodically when watching a movie.This happens even after disabling the screensaver, in vlc:vlc -> tools -> preferences -> show settings 'all' -> video -> disable screensaver
Howto disable screensaver when vlc is running, under kde?
kde;vlc
The problem is that the X screensaver is still enabled, as shown by typing xset q on the command line:Screen Saver:  prefer blanking:  yes    allow exposures:  yes  timeout:  0    cycle:  600The solution has been given in this thread.Just issue xset s noblank -dpms on the command line.But it is more convenient to create a ~/bin/disable_xsc.sh file containing#! /bin/bash# disable the X screensaver# The kde screensaver should still work, though# http://opensuse.14.x6.nabble.com/Disabling-display-power-management-td3039820.htmlxset s noblank -dpmsexit 0Make sure that this script is executablechmod u+x ~/bin/disable_xsc.shotherwise you would get a blinking kwrite in the taskbar, kde hanging, the taskbar responding very slowly, firefox would hang on startup, ...if you forgot to chmod, just kill the offending kwrite process, and issue the chmod command.Finally, going to the kdeconfigure desktop -> system administration -> startup and shutdown -> AutostartAdd scriptin the shell script path, type ~/bin/disable_xsc.sh, leave the Create symlink checked. This script will be run on startup.Note that the kde screensaver will still work correctly, when vlc is not running. Its configuration can be found inconfigure desktop -> Hardware -> Display and monitor -> screen locker
