Hey thanks Maligree.
and sure enough the screen went blank after 3 seconds.
Next I added:
to the monitor
section of xorg.conf.
After restarting X, the screen no longer went blank after 3 seconds, but still went blank after 10 minutes.
I then again did:
and the screen started blanking again after 3 seconds.
I then did:
and noticed that while the DPMS is disabled, the built in screensaving of X is still working uless we do:
So I then put the following line into the .bashrc file:
But the screen still blanks after 10 minutes, although judging from the output of xset -q below, there should not be any more screen blanking:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 0
default colormap: 0x20 BlackPixel: 0 WhitePixel: 65535
Bug Mode: compatibility mode is disabled
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Disabled
Is there another underlying system external to X which could be blanking the screen after 10 minutes?
