Forgot to add the system info
Operating System: Arch Linux 
KDE Plasma Version: 5.27.3
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8
Kernel Version: 6.2.8-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700X 8-Core Processor
Memory: 15.5 GiB of RAM
Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MS-7A37
System Version: 1.0

I also have this problem on my machine. I will try to gather logs (if it happens again) and versions tomorrow, but here's what I know about my system now:

Operating System: Arch Linux
Graphics Platform: Wayland
Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor
Memory: 31.3 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 3060/PCIe/SSE2
Manufacturer: ASUS

It has been happening for the last 1-2 weeks. Doesn't happen every time, but about 5 times so far. Seems to be more likely to occur the longer I leave the system alone. Disk LED keeps blinking, so system clearly isn't frozen. I haven't tried SSH. Can't switch tty or replug monitors. Must force reset the machine via power button.

Comment 4 Marcelo Bossoni 2023-03-27 23:23:12 UTC

Did a bit more digging... Apparently this is a problem with night colors on wayland since Nvidia doesn't support it.
Apparently if night colors is applied while display is off make it unable to wake again

Try setting it to off

Comment 5 tsweet64 2023-03-27 23:41:43 UTC

Good find. I do indeed have that enabled despite it not working. I will turn it off and see if it fixes.

Comment 6 Nate Graham 2023-04-03 22:16:36 UTC

Cool, so it should already be fixed by https://invent.kde.org/plasma/kwin/-/commit/ec593a23644910a19ec2284aa753678228f19937 in Plasma 5.27.4.
