kblankscrn.kss

[Tom_ZeCat]

When Kubuntu boots I get a bunch of windows open named "kblankscrn.kss". I researched this problem before and found how to kill them all with this terminal command:

killall -9 kblankscrn.kss

That works, but it would be nice if I could boot up my computer without having to bother with this. I keep thinking one of the updates will finally solve this glitch, but it persists.

After you have killed them.

System Settings > Startup & Shutdown > Session Management > On Login > Start with an empty session

Thanks. I just put that in. I'll see what happens when I reboot.

Edit: I'm back after the reboot. It worked! Thanks.

Noticed this bug since about ±5 days ago. Snowhog's tip works but is no satisfactory solution for me because I then need to re-add my superkaramba widget stuff to the desktop.
So, until there is a fix, I will just continue to close the 2x kblankscrn windows after logging in.

Add a 'daemon' /1/ to clean the process list

Simple infinite loop - kill the older '.kss' processes if there are more than 1.

#!/bin/sh

while true; do
   howMany=`ps -ef | grep -v grep | grep '.kss' | wc -l`

   if [ $howMany -gt 1 ];  then 
      pkill -f -o '.kss'
   fi
   sleep 30 
done

Start the 'daemon' with the KDE System Settings > Startup and Shutdown > Autostart
