How to do dpms cycle ?
On the console, just wait for the screen to blank. In X: xset dpms force off will force a dpms cycle.
That would valid if we were able to log in X. Is there a way to do it if we are still in the console?
I think you can adjust the console blanking with setterm. Can you start X and force a dpms cycle even if the screen is garbled?
