I'm running Linux Mint 17 MATE edition and have turned off both the screen saver and Power Manager and the screen still goes blank after 10 minutes. I'm also running Ubuntu 14.04 which does not have this issue.
I believe the problem was addressed earlier in this post from 2008 Fix for screen going blank after 10 minutes and may have something to do with DIsplay flags. However the fix is apparently no longer applicable or at the very least I could not find xorg.conf
I think this thread was having the same issue but went unanswered ... Mint 16 xfce x64- Screen time out on laptop...
Here's the solution: Add these lines to the end of your /etc/X11/xorg.conf:
Code:
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection
Any help would be much appreciated.
Thanxz!
