mageia 9 - plasma (( suspend & sleep )) features not working

[sameeeer]

hello again people ..... hope you enjoy the last version of mageia which currently is 9
...........................................................

anyway , i am here just to ask , if anyone faced what i am facing now

my system now is running plasma-desktop and till now is working fine but these two features (( suspend & sleep ))

if i put the system in one of them it will respond and go either as i want in sleep state or suspend state

but if i try to wake the system up , the system will not respond and and cannot be woken from that state

so what is the problem here ..... i hope i explained may point here correctly for all you ..... and i hope to you all to have a good time

Is there no sign at all of it waking up, i.e power LED?
No reaction at all on screen?

[sameeeer]

no the screen will still be black till it get a signal to start again which it didnt happend .... on the other hand when the system goes in lock screen state and screen become black (( standby state )), then i can easlly wake it up by either mouse movment or keyboard buttons


quoting the previous post is not appropriate. ~Germ

What I meant to ask is if the computer wakes up but not the screen.

I have that problem on my old workstation with Intel P55 chipset, when using nvidia proprietary driver with GTX750 GPU and desktop kernel, monitor is Philips 436M6.

Workarounds is in my case is to either
* power cycle the monitor
* use graphics driver xorg modesetting
* use our linus kernel

Hello! I had the same problem with the black screen after suspending using Mageia Gnome.
I found a very simple solution following the link below:

"Turning off 'Screen Blank' under power settings solves the issue. power settings window"

farnas, that appears to be a Gnome-specific fix. I'm sure the user went through the power options in Plasma.

Hello everyone, the problem still persists here even with Gnome, when it goes to sleep/suspend automatically, screens remains black after trying to wake it up.
I have to completely shutdown the laptop by pressing turn off button. So, in my case I can't use "Screen Blank" and "Automatic Suspend". It looks like that the problem beyond Gnome/Plasma in something else... Probably a bug!

Same as this?

Not waking up from hibernate at all, and waking up but failing to turn on the monitor again are pretty different I'd say.

@farnas: Please create a separate thread for your issue, and also provide some more details about your hardware (laptop or not, maker/model ...) and how your monitor is connected.

[farnas]

Yes, very similar, I think.

Hello @doktor5000,

I don't know how to create a separate thread yet, but I would like to share how I solved the problem:
I installed newer kernel 6.5.11 from the Cauldron/Testing repository and the problem with Suspend/Sleep is gone.
Anyway I'll test few more days until I can make sure that it's working and no other issues came up.
I use this laptop:
