How to disable screen blanking?

[Ralf Mardorf]

Hi :),

how can I disable screen blanking for Quantal?

spinymouse at qrc:/mnt/music/quantal/01song$ sudo xset -dpms
[sudo] password for spinymouse: 
spinymouse at qrc:/mnt/music/quantal/01song$ xset s off
spinymouse at qrc:/mnt/music/quantal/01song$ setterm -powersave off -blank
0 setterm: cannot (un)set powersave mode: Invalid argument

I already disabled the screensaver and power settings by GUI.

Regards,
Ralf
