Can I resume Ubuntu after suspend by shortcut from keyboard?

I have a docking station with thinkpad and an external monitor. My laptop is always closed, so I need to open it and close again to resume system, it's annoying.

If the external keyboard is USB, you probably can, although it depends on your motherboard.

Check /proc/acpi/wakeup it shows all supported wakeup sources and their states. To toggle the state, simply echo the wakeupsource name back to the same file.

Example, to enable/disable wakeup from a usb device on my system, i do:

# cat /proc/acpi/wakeup |grep HC
EHC1      S4    *disabled  pci:0000:00:1d.0
EHC2      S4    *disabled  pci:0000:00:1a.0
XHC   S4    *disabled  pci:0000:00:14.0
# echo XHC > /proc/acpi/wakeup 
# cat /proc/acpi/wakeup |grep HC
EHC1      S4    *disabled  pci:0000:00:1d.0
EHC2      S4    *disabled  pci:0000:00:1a.0
XHC   S4    *enabled   pci:0000:00:14.0
