Where to start to debug KDE suspend/sleep problems?

I have many problems that can occur after sleep:
1. Screen is turned into random patches of rainbows after waking up from sleep
2. Black screen with cursor if system woke up from sleep while 2 users are logged in
3. Screen keeps going randomly black for 1 second after I wake up from sleep.

How can I begin to dissect these problems and find their root causes?

system journal, start with figuring what hardware you're actually using.
https://wiki.archlinux.org/title/NVIDIA … er_suspend - though that's enabled by default in most recent versions.

Re: Where to start to debug KDE suspend/sleep problems?

I have already followed the whole page. I have the following hardware:
0a:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070 Ti] (rev a1)
    Subsystem: ASUSTeK Computer Inc. Device 861e
    Kernel driver in use: nvidia
    Kernel modules: nouveau, nvidia_drm, nvidia

Would I also need to look in kde specific or logs specific to the GPU itself?

Post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st
