Suspend/Resume stopped working on my Dell 7375 2-in-1

Hi all,
Here's the deal, suspend has stopped working on my laptop. It used to work fine. Not sure why it quit working (kernel update, maybe?). What happens is, when I close the lid or suspend in any other way, the screen will go black but I can tell by listening that it did not suspend. At this point it has crashed and will not respond to any type of input.

Update: I am pretty sure this is a KDE issue.

Here is my inxi output:

Well... Installed Manjaro-Gnome and suspend now works. Will see what happens as time goes by. Not a big Gnome fan but I'll use it for a while.

If you would like to test KDE again try disabling KDE's compositor before suspending. The KDE compositor has been found to be preventing proper suspend on some help threads recently.

Also test different kernels with KDE as the kernel can also in combination with other things cause this type of issue. Your inxi has kernel 5.2 listed. I would test more recent kernels, as well as the LTS kernels 4.19 and 4.14.

I did read that suggestion about disabling compositor and tried it, no luck. I also tried different kernels, as well. When i originally installed Manjaro KDE suspend worked fine. I believe it was 4.19 kernel. Just not sure what caused the issue in the first place.

I'll try reinstalling KDE again after I do a BIOS update (which means installing Win 10... ick). Thanks for the response.
