How do you let Linux power off the monitor after xx minutes of inactivity? Here's the scenario:
I have two Linux boxes connected to one monitor. The monitor has two inputs, so that's no brainer. It has a button on the front panel to switch between the inputs.
One (A) is the Linux workstation I use every day. The other (B) is the Linux server. I use graphical login (gdm) on A, and text login on B.
The problem is, A is power management aware and shuts down the monitor after 30 minutes (the value I set) of inactivity., but B doesn't do that. As the result, the monitor is always on since it will automatically switch to input B when there's no signal coming from input A.
What can I do to make B aware of energy saving?
