I have a laptop with Neon installed and after you close the lid, or manually make it sleep. You cannot make it wake up again, no matter what buttons you press or what do you, it won't wake up. The thing i've been doing so far is to hold down the power key and then restart the computer, which is slightly annoying since it takes a while for the laptop to complete restart.
I've heard that others have the same problem but I have yet to see a fix for it. Does anyone know a solution?

I have this same problem! Please, please help!

I'm using a new Lenovo Yoga 6 13". The system information from System Settings say:

KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.3
Kernel Version: 5.11.0-36-generic (64 bit)
Graphics Platform: X11

Processors: 12 x AMD Ryzen 5 4400U with Radeon Graphics
Memory: 7.2 Gib of RAM
Graphics Processor: AMD RENOIR

I've seen some forums suggest that I should get an Nvidia driver, while others say that causes problems, and still others say that it won't do anything. What additional information can I provide so any of you can suggest some solutions? (And how do I find that information? I'm still a relative noob to Linux and very new to KDE Neon.)

Many, many thanks in advance!

UPDATE: I've been fiddling with the settings and found that I can get it to go to sleep now if I tick the box "Inhibit automatic sleep and screen locking" (ironically...). HOWEVER, it only goes to sleep once before crashing. In other words, it can go to sleep once and seems to be fine waking up, but if it falls asleep a second time, then I have to hard boot it.

It will also completely avoid sleeping if I turn off the lock screen and keep the laptop open.

When it does wake up (if it does), I get a bizarre, pixelated screen that a friend suggested might be an issue with the graphics driver. This issue seems to be in keeping with what others online have said about the sleep issues being related to a graphics driver.

I currently have amdgpu as the driver and everything seems to be working except for this sleep issue. Not sure what other driver to use, as I have an AMD graphics card and it doesn't seem to want to let me install amdgpu-pro. It seems like the start/wake-up process doesn't think there's a graphics driver, perhaps?

Happy to provide more information if needed. Welcome any suggestions and solutions!

Thanks!

Hello !

Did you ever manage to solve your issue ?

I just bought a new-for-me laptop for school and suspend is super important since i'm constantly moving between classrooms. I also got KDE Neon now with kernel v5.15, i also upgraded to 5.19.3, but I have this same exact issue, laptop sleeps properly but then the screen remains black.

Greetings,

Alex

No i did not, although I moved to Kubuntu for a while before switching back to Neon and then the problem was gone. I'm still not sure what actually caused the issue, but a full reinstall of the newest version worked for me. That might not be a viable option for you though.
