So, ever since I switched to xfce, I have been having some issues with suspending my system.

My system wakes from sleep normally most of the time, but every once in a while, my computer will turn on, and my status lights will turn on, but my screen won't initiate. I really have no idea why this happens, and it's been bothering me for too long.

I have a sneaking suspicion it has to do with xscreensaver. This is because I have disabled it, but I managed to wake my computer immediately one time and was greeted both to the lightdm login screen, then afterwards the xscreensaver login, which shouldn't be there.

  • I have similar problem. As a workaround, I press Ctrl+Alt+F1 then Ctrl+Alt+F7. After this, X11 session will be reactivated in a few seconds. – Dávid Horváth Sep 2 at 14:02
  • @DávidHorváth ah, you posted this right after it started happening again. I guess its another bug? Ill try that next time. – SpecialBomb Sep 2 at 18:48

Some kernel version have problems waking from a deep-sleep. Go into your BIOS and search for "C States" or "Sleep states" or similar. Change the maximum value to 1, or even to off, and see if that removes the problem. These "C States" are used to moderate the CPU power consumption, so you want to allow the highest-value state that your kernel will wake up from.

  • alright, ill look at that. It will take a bit to test it, as the chance that my computer will wake properly is seemingly random. – SpecialBomb Jan 16 '18 at 0:01
  • That didn't seem to work. I only had full power mode and ram power only mode, and I still had issues with either one of them. – SpecialBomb Jan 17 '18 at 18:54
