I am using Xubuntu 20.04 LTS on a desktop. I have a wireless keyboard and generally sit away from the computer even when working on it. I have assigned a keyboard shortcut to put the computer in sleep by just hitting Super+F12. I remember when I used Windows, I could wake the system from sleep by hitting enter. Now I cannot wake my system from sleep by using the keyboard. I have to go to the CPU and press the power button to wake it up. I tried the solution given here using dconf-editor. But it didn't help, because I am using Xfce and not Unity/GNOME. How can I do it? Thanks.

    "Now I c"annot wake my system from sleep by using the keyboard. " is a BIOS function. So start there. Make sure power functions do not disable or reduce power to ports. Next: make sure you can use "sleep" (hibernate/suspend) and it is not just turning the system off (find the command line function to hibernate ;) ) – Rinzwind Dec 13 '20 at 09:39
  • sudo systemctl hibernate for instance or sudo pm-hibernate – Rinzwind Dec 13 '20 at 09:45
  • @guiverc I have edited the question to include the version number. It is Xubuntu 20.04 with Xfce 4.14 – LordRishav Dec 13 '20 at 10:04
  • @Rinzwind The sleep here is suspend, triggered by systemctl suspend, and not hibernate. Also, I have Windows in dual boot too, and I can still wake it up by hitting enter – LordRishav Dec 13 '20 at 10:06
