Typing the commands manually didn't work either, I also tried disabling LID0 (sudo sh -c 'echo LID0 > /proc/acpi/wakeup')
No luck with that too, I verified the command working with
cat /proc/acpi/wakeup
It shows XHC1 S3 *disabled pci:0000:00:14.0
When I close the lid it suspends, when I open it again I just get a black screen (fans still on, no way to get to another tty)I also tried suspending via the menu / power button: same results
