In your terminal :
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
To disabled it for the current session, run:
xset s off
You can put this in your .xsession
file to disable it upon every login.
Disable screen saver/power management?
I was trying to figure out almost the same issue her for a Ubuntu 12.04 client which should run 24/7 without any blank or black screen. Maybe my way to fix things can help you, too:
First of all, I changed a line in /etc/default/grub, in order to switch off power management at all.
Old:
Code:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"New:
Code:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"After a reboot, the terminal command
Code:dmesg | grep -i ACPIinformed me that ACPI has been disabled.
Then I created a new file xset_off.sh in my home directory. Its content is
Code:!#/bin/bash exec xset -dpms s 0 0 s noblank s noexpose s off(Don’t forget to make this file executable with
Code:chmod +x ~/xset_off.sh.)
In order to have this script run everytime when your X window environment is launched, you can either add it to your autostart objects in the GUI desktop. Or you create a new file ~/.config/autostart/xset_off.sh.desktop.
Mine has the following content (autogenerated by the GUI desktop):
Code:[Desktop Entry] Type=Application Exec=/home/XXXXXXXX/xset_off.sh Hidden=false NoDisplay=false X-GNOME-Autostart-enabled=true Name[de_DE]=xset off Name=xset off Comment[de_DE]=Bildschirmschoner aus Comment=Screen Saver OffThe next time when you have booted your system, a simple check of the xset parameters with
Code:xset qshould inform you that both Screen Saver and DPMS have successfully been switched off.
