Ubuntu 20.04 doesn't wake up after suspend or restart

kn flag

I just got a new PC and installed Ubuntu on it, which I'm completely new to (literally installed 3 days ago). I just found out that when I try to either restart or suspend the PC it turns into a black screen that doesn't respond.

I found a lot of similar questions like this or this but they seem to only focus on suspend and my problem seems to also be when I restart, so I wasn't sure if they are related. I tried following the second link and ran sudo ubuntu-drivers autoinstall && apt install gnome-screensaver but that didn't seem help.

As I'm completely new in this community I'm not sure what details to add, but my CPU is AMD Ryzen 9 5900X 12-Core 3.7GHz and GPU Nvidia GeForce RTX™ 3090. When I go to software & updates / additional drivers it seems like it's on nvidia-driver-470 (proprietary, tested). I tried switching to nvidia-driver-470 (proprietary), to nvidia-driver-460 (proprietary), or to X.Org server, but nothing worked.

Running nvidia-smi I get: NVIDIA-SMI 470.86 Driver Version: 470.86 CUDA Version: 11.4

Please do let me know if there is any other information needed to solve this.

Seems like after trying various things only changing the driver to 495 from 470 worked. There might be another solution but this seems to solve it (while apparently not breaking anything else)

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.
