After about 10 minutes, Xubuntu 14.04 goes to sleep all by itself. I've set up the shuffle on the music player and it only gets through 3 songs before I have to sign in again. There is no screensaver installed and the power setting for AC is set to never shut down. So, what do I need to do?
light-locker is the new screen locking program in Xubuntu 14.04. If you disable light-locker, it should stop locking your screen.
How to disable lightlocker
- Go to settings manager > session and startup > application autostart and disable light-locker, which is titled “Screen Locker (Launch screen locker program).”
- Reboot your machine and it should stop locking. Alternatively, start up Terminal with Ctrl+Alt+T and run
On my Xubuntu 14.04 install, even when I had Light Locker completely disabled, my screen still blanked after about ten minutes. The solution to my problem was to run the following command:
sudo xset s 0 0
Make sure you run this command from your desktop session and not through an ssh session, or the DISPLAY variable will not be set and this command will not work.
a bug report has been filed: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/498366
even more info: http://www.shallowsky.com/linux/x-screen-blanking.html
This worked for me:
sudo mv /etc/xdg/autostart/light-locker.desktop /etc/xdg/autostart/light-locker.desktop.bak
It was based on some info in this bug report: https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1287255
You can edit the file at
/etc/xdg/autostart/light-locker.desktop and add the line
as documented here. This will disable
light-locker globally, which is nice if your family starts complaining that they cannot unlock their desktops. You can copy the file to
~/.config/autostart first to disable it for a specific user only.
If you use nvidia xorg drivers and have gone as far as to nuke light-locker and gnome-screensaver from your system,
sudo xset s 0 0 doesn't work for you (your screen still blanks),
xorg.conf wherever you saved it (typically saved in
/etc/X11/) like so:
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
save, and reboot
your screen should no longer blank after 10 minutes
