Need assistance Debugging Suspend issue

Post by 0lzi » Thu Oct 17, 2019 12:02 pm

Hi Everyone,

First of all , I would say im technically savy but in the Linux world fairly new.

OS: Linux Mint 19.2 - Cinnamon
Kernel: 4.15

Issue :

Power button to suspend is intermittent. Sometimes it will suspend properly, and the PC appears to be off ( no fans going, lights in the case off , monitors off etc ) other times it doesn't ( fans spinning, case lights on , monitors off ). When it suspends properly i can wake it fine ( WOL or power button ). When it doesn't suspend properly sometimes it cant be woken and have to force it off to turn it back on.

What i have tried :
  • Checking BIOS for WOL / Wake on PCI / PCIE - Settings are correct here
  • Checking BIOS for S1 / S3 / S5 Sleep state options - Settings seem fine here
  • Running 'suspend' from terminal - 50% of the time would suspend
  • Running 'sudo suspend' - no issues and suspended correctly 3 times out of 3
  • Going to 'Menu' -> 'Power icon' then selecting 'Suspend' from menu - worked again 50% of the time
  • My Alias for suspend = alias bye='echo bye && sudo systemctl suspend' this works most of the time , mainly use this to suspend my machine when i remote ssh to it
