waking suspended desktop box by hitting keyboard key??

[robert]

Hi there

I am running ubuntu 20.04 (since a couple of months, so it was gradually updated 
..).

Now I would like my box to go to sleep when idle for some times.

This can easily be done from the power settings.


What I did not find, was a way to wake it up by hitting a keyboard key.

Can anybody of you give me instructions on how to set that up?


Thanks a lot

stay save

Robert
