Zorin OS 16.3 Pro, Standby Mode not working

Hi to all,
if my machine is switching into standby mode, it is not possible to wake up the machine! The only one possibility is to hold the power button and starting the machine again!
The same trouble than before in the 16.2 Version.
In Ubuntu with Kernel Line 5.19.0-x no problem at all.
My machine: Minisforum Neptun Series HX99G, AMD Ryzen 9 6900HX with RX6600M GPU.
Any idea?

Greetings from Cologne, Germany,

You might try the TuxInvader 6.2 kernel:

sudo add-apt-repository ppa:tuxinvader/lts-mainline

sudo apt update && sudo apt install linux-generic-6.02

Thank you for your tip, but it still found something to try:
I installed the Mainline Kernel Package and installed the 6.09 kernel.
After that i change in the bios "Secure Boot" and restart the machine.
The machine switching in stand by mode, i can wake up my machine but no the monitor doesn't wake up!


This change - was it to disable Secure Boot?


Yes, that was the change, but the monitor doesn't wake up, so i had to do the same from befor: hold the power button to shut down and restart the machine over the power button!

Still, I suggest trying the other kernel I suggested or also the sudo apt install linux-generic-6.03

This is a common issue, usually caused by Graphics driver. You have AMD, which is wrapped in the Linux kernel.
You might also try the 5.19 kernel - since you already confirmed that as working.


I tried the 15.9 Kernel, but the same than before; i think i have to wait for Zorin 17, in hope that these problems are fixed!

Computer not waking from sleep is a pretty common issue. If you do a net search on it, you will see the hits.

Just be mindful to exclude the search hits that center on Windows instead of Linux.

The causes can be quite diverse so it can take a lot of persistence to resolve it.
