I have a fresh installation of Ubuntu 19.04 on an Asus Vivomax laptop. It has Intel Celeron N3350 and nvidia GF 810m running in Prime mode. Suspend just turns off the screen for a moment and then takes me to the lockscreen - and for some reason the desktop image fails to load after that. As for hibernation, I couldnt find any button or setting to enable it. When I try "sudo pm-hibernate" it says there is no swap partition, even though I created and turned on a swap partition in gparted.. can you help me plz? I need the ability to at least suspend my leptop, otherwise I will be forced to use another OS... thanks in advance!
EDIT: After updating to the latest BIOS (My model number is ASUS X541NC) suspend works, but "sudo pm-hibernate" still gives the "Swap header not found" error
