I have a Razer 2020 15 base model with manjaro newly installed.
I’ve had some issues regarding two things.
Firstly, after a while in sleep or just a while of use the mouse starts stuttering and I can see large CPU spikes on btm when I start moving the mouse, without the mouse responding. This is when I use my trackpad.
The second problem I have is when i close the laptop manjaro, sometimes, doesn’t go to sleep, i believe it almost keeps the screen on even though I’ve set it so that it should go to sleep in the system settings.
I hope you have some good input on this, literally the only two issues I’ve had with Manjaro on my crisp new razer computer
