Power save mode

[morind79]

Hi all,

I have Debian on SD Card, and I installed xdm to be able to have X via SSH.
I also have a screen connected to the board via HDMI.
As I have "service xdm start", on the screen attached to A20 I see the login GUI window. But after a while, this screen go to sleep mode, and it is impossible to wake it up (keyboard or mouse attache to A20 works, but screen stays off).
Question -> How I can disable HDMI to go in power save mode ?

Thank you

Best regards
Denis
