Error in sleep mode

I run Manjaro KDE for 2 weeks now. Before that, I used Pop!_OS.
My laptop is the 2020 Acer Swift 3 (ryzen edition).
When I put my laptop in sleep mode, (i.e., closing and opening the lid) the screen goes black. TTY doesn’t work. I have to restart to use my laptop. Even hibernate does the same thing. So everthing in energy saving settings that was set to sleep,I set them to Lock screen. But this kills my battery very soon. Does someone know what to do? I am ready to provide whatever information necessary.

Quick Update: After I upgraded to Linux 5.8 kernel, sleep mode works twice (sometimes thrice) and then the same black screen is back. But this time I can see the cursor and it can move around.

As you’re using the

What you did is the right course of action: update to the latest kernel as AMD’s drivers are built into the kernel and they’re good at fixing bugs.

Another thing to do is to install the latest Long Time Support (LTS) kernel in case the 5.8 would break something…

The best thing to do is to file a bug with the AMD kernel team
