Can’t resume after suspend with 515 driver on Ubuntu 20.04

I’ve seen several variations on this question, but might as well ask my own up-to-date version.


  • Ubuntu 20.04
  • GPU: GeForce RTX 3090
  • Driver: 515.43.04

System boots with no issues - running graphics off of motherboard integrated graphics, only using GPU for compute (DL research).

Problem: I’m unable to resume from suspend. Only way I’m able to get the system back up is by doing a hard power off, power on. Don’t get the POST beep when I attempt to resume from suspend.

Looking at previous answers, this is not an upgrade from 470. Already purged all sytemctl processes related to suspend / hibernate / etc.

I’ll take any advice I can! Novice to linux and Nvidia.
