Hello all,
I have Sapphire EDGE-HD Mini PC, attached to a LG TV with HDMI cable. The OS is Fedora18, from live CD.
After 1 hour, the TV turns off. I have tried several things:
1) /usr/bin/gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
2) editing /etc/X11/xorg.conf.d/10-local.conf and adding:
Section "ServerLayout" Identifier "ServerLayout0" Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" EndSection
Section "Monitor" Identifier "Monitor0" Option "DPMS" "false" EndSection
However, it does not help. When I grep DPMS in /var/log/Xorg.0.log, it says:
[ 26.451] Initializing built-in extension DPMS [ 26.654] (II) RADEON(0): No DPMS capabilities specified [ 26.709] (==) RADEON(0): DPMS enabled
Can someone give me a hint how to disable it completely?
Thanks in advance,
