One more topic about : monitor won't wake up

[Zant]

Hello,
I'm running Zorin OS 18 Core on a mini computer : GMKtec NucBox_G10
My graphic card is : AMD Radeon™ Vega Mobile Gfx

As you got it from the title, when I set my computer on sleep mode, I can't get the monitor to wake up, only the computer wakes up ( as I can infer from the glow of the power button : it stops flickering when I press the power button )

I've already done some research on the forum, I've tried a few things, including the BIOS settings : nothing worked.

In particular, I've tried to type xset -dpms in a terminal.
I've deactivated secure boot, etc... I've done several things I found on the forum.

This problem is really annoying...

I haven't tried to modify the kernel ( pretty afraid of that ).

Do you have an idea what I could try ?

Thank you in advance : I like Zorin OS a lot, but that problem is ruining everything

By the way : I got that info :

and about kernel :

And I forgot to say that it works fine with Windows 11.

Welcome to the Forum!

@Zant

And I forgot to say that it works fine with Windows 11.

Does this mean, that Windows is still installed? If yes: Is Fast start-Up in Windows disabled?

@Zant

and about kernel :

Did You installed the Kernel because the nwer one didn't worked on Your Machine?

Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE

When it runs in Wayland, You could try it with switching to X11/Xorg. To do that, go to the Login Screen. Click there on Your Profile so that the Passsword Field appears. When it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose Zorin Desktop on Xorg''. Then log in.

Hi, thank you for your answer.

@Ponce-De-Leon

echo $XDG_SESSION_TYPE

it returned X11 but it was Wayland before, I've tried to change for Xorg ( it displays X11 as a result ), but it didn't work.

@Ponce-De-Leon

Did You installed the Kernel because the nwer one didn't worked on Your Machine?

Sorry I didn't understand ; I've tried to update Grub but I'm afraid of modifying Kernel... Maybe I've modified it without knowing ?

I forgot to say I have dual boot windows 11 / Zorin, one disk ( 256 Go ) each, and it boots on Zorin as first choice.

@Zant

When You want Xorg, X11 is the right Output. It belongs together.

@Zant

Do You remember what You have done? Because the 6.8 Kernel is an older one. Currently, there would be 6.14 and the newst 6.17 on Zorin 18. Do You have now a displaying GRUB Menu at Start-up?

@Zant

I forgot to say I have dual boot windows 11 / Zorin, one disk ( 256 Go ) each, and it boots on Zorin as first choice.

Then, some Questions:

• Are Secure Boot and Fast Boot in BIOS disabled?
• Is Fast Start-Up in Windows disabled?
• Is Your BIOS in UEFI or Legacy Mode?
• What Tool did You use to create the Bootstick?

@Ponce-De-Leon

...Because the 6.8 Kernel is an older one.

FYI. Z17.3 is using kernel 6.8.

But the User wrote:

@Zant

I'm running Zorin OS 18 Core

That was the Reason why I asked.

[Zant]

I've reinstalled Zorin OS 18 and now the kernel is : 6.17.0-14-generic, but the problem remains.
( I will answer your previous questions soon )

[Zant]

It seems the problem ( monitor won't wake up after computer being set to sleep mode ) was coming from the AMD Radeon graphic card, because I received my new GMKtec mini computer today and it works fine : I don't have the same problem I had with AMD ; the new one has an Intel processor and graphic unit, it will wake up just fine.

So, now, I will send back the AMD computer and ask for refund.

[Zant]

This is the answer I got from the GMKtec support :

" Try using the "shallow sleep" (s2idle) mode instead of the "deep sleep" mode.

To set this mode:

Open a terminal and edit the GRUB configuration: sudo nano /etc/default/grub

Locate GRUB_CMDLINE_LINUX_DEFAULT "quiet splash".

Add mem_sleep_default=s2idle within the quotes, making it look like this:

`GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=s2idle"``

Save (in the nano editor, press Ctrl+O, Enter, Ctrl+X).

Update GRUB: sudo update-grub Reboot and test sleep mode.

If the above steps are ineffective, it is recommended that you switch to a Windows system.

Thanks for your patience and cooperation.

Warm regards,

I hope it will help someone.

edit : the monitor will wake up, now, but the computer is NOT in sleep mode, it won't "stop running", so... That's not exactly what I want, this is not sleep mode.

The instructions ask your to apply S2Idle, rather than S3 - deep sleep.
So it is a "sleep" state, but a shallow one.

What this shows is that the ACPI firmware is likely incomplete and the recommendation they gave to use S2IDLE demonstrates that they know that it is.
Second possibility is that the firmware does not actually fully support S3 deep sleep - but this also would mean that they are aware that it does not.
