@bsniche Didn't test that that much. But systemctl suspend works without any problem and it does resume without any problem.
I thought s3 is normal standby (suspend to ram) and s0 is just powered on state?
In the UEFI Settings of the notebook there's a sleep state Option, where you can switch between Windows 10 and Linux. I set it to Linux.
Edit: I have got the live 4.1 Plasma Live Iso to work. I'll post a guide probably tomorrow. In short, i needed to configure fbdev driver to use a specific pci bus. sddm didn't want to launch, but I could run a plasma session using startx and then install it. Maybe it's easier on budgie and lightdm, will test that later too.
