Hello,
I have a Raspberry Pi B+ running under raspbian.
Usually it is run as a "headless" device.
That is:
- In the morning the Raspberry Pi B+ gets booted and starts Samba so that other machines can access files stored on external usb-hard-disks attached to the Raspberry Pi B+.
- When something needs to be done on the Raspberry Pi B+ itself (e.g., updates, setting new passwords, configuring Samba), this is done via Windows Remote Desktop and xrdp or via putty/ssh and the ssh server.
But the Raspberry Pi B+ is also attached via a kvm-switch to usb-keyboard/mouse and hdmi-monitor.
The Raspberry Pi B+ boots into console mode.
When nothing is typed on the console within let's say 15 mins, the Raspberry Pi B+ will go into power saving mode which means that when switching the kvm-switch to Raspberry Pi B+, the hdmi-monitor will show blackness and the Raspberry Pi B+ will neither react on keystrokes from the keyboard nor react on mouse-movements.
(After entering power saving mode, the Raspberry Pi B+ is still accessible from other machines, e.g., via Windows Remote Desktop/xrdp and via putty/ssh. Accessing the samba-shares provided by the Raspberry Pi B+ is also not a problem after entering power saving mode.)
Is there a method, e.g., a combination of keystrokes or the like, for switching power on again via (the kvm-switch's) keyboard/mouse after the Raspberry Pi B+ has entered power saving mode?
(I don't like to disable the power-saving features completely as usually the Raspberry Pi B+ is run as a "headless" device.)
Sincerely
Timo
