I recently got an HP Envy x360 with the new ryzen 4500u CPU. After fixing a bunch of different issues and updating to kernel 5.7, there is a few bugs that remain. First, the laptop won't work after I suspend for more than 20 min. When trying to do so. the laptop opens to what was opened before closing the lid, but the cursor shows some kind of artifact and nothing is working. Secondly, the microphone is not working, although this is much less of an issue for me and I can always get an external one later on.

Any tips for suspend issue?

Running Ubuntu 20.04

Not sure about the 20 minutes part, but I wonder if this is related to hybrid sleep mode.

e.g. Laptop goes to sleep/suspend, then a while later it hibernates and flushes memory/state to disk.

It's possible that suspend/sleep is ok, but hibernate is causing issues.

I'm not sure if it's systemd that's responsible for this, but /etc/systemd/sleep.conf seems to indicate that hybrid sleep and hibernation are enabled by default.

There may also be some hibernate-related settings in the gnome power management area that could be worth checking.

As a quick test, temporarily disabling hibernate completely may be worth trying to isolate the issue.

There's a bunch of GPU driver improvements in the 5.8 kernel as well (currently in RC stage): https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc2/

Wish I could tell you something more useful, but mine hasn't been delivered yet. When it is, I'll probably run into the same issue(s) and will have good motivation to try to deal with it.

That is because suspend to RAM (S3) was replaced with "modern-standby" (S0ix). Here is my workaround on how to enable and enjoy S3 again on HP 15s-eq1009 with Ryzen 3 4300U. Hope it will be useful for you too.
