Changing your reboot/logout timeout
Is the reboot /shutdown timeout time excessive. Would you like to change it to something more reasonable for you like 5 or 10 seconds instead. If so then preform these simple steps.
Install the program sd using synaptic .
open a console window and su to the root user
Now enter the following command
sd "30" "15" /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/logout/Logout.qml
This will change the reboot/logout timeout from 30 seconds to 15 seconds. If you would like to use a 5 or 10 second timeout change the 15 in the above command to either 5 or 10
Once you have the command set for the timeout you want press Enter
Now the next time you shutdown or reboot you will ne see your new logout/reboot time.
