Ubuntu 20.04 with Nvidia crashes on suspension

cn flag

When I suspend the computer, this screen shows up and I can't do anything except restarting with REISUB or hard reset.

When the system has just booted up, it can go to suspend, but after being used for a while, it crashes on suspension.

System: Ubuntu 20.04 Nvidia GTX 950M Nvidia settings:

  • Prime mode: NVIDIA (Performace mode)
  • PowerMizer: Prefer Maximum Performance

I think the problem comes from NVIDIA driver. I tried almost every version of NVIDIA driver and all of them give the same problem. The issue only stops when I switch to use Intel GPU - power saving mode in NVIDIA settings.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
