This just started after installing a fresh copy of tumbleweed a few weeks ago, I then installed Linux mint to see if it was /system partition encryption/ OS / desktop based (KDE/Gnome) with no change. The only thing I can think of is the Kernal version was newer on the freshly installed systems, but I believe Mint might be using an older kernel. I have removed the system volume encryption also with no change.
The only other piece of data that might be relevant is that I have disable sleep and believe it still freezes when the monitor turns off.

Update after much troubleshooting with my Linux admin buddy.
System freezes when the screen turns off every time.
I have used the following to shut off my screen for years, but after running this command, I not only crashed (with a flashing caps-lock light) complete with kernel panic and hard reboot. All this for a simple screen shut off.
Xset dpms force off
So this isn’t a sleep issue its a screen shutdown issue. I may have to open a new support thread.

My Latitude 5591 does and works fine with it and s2idle, but I had a XPS 13 years ago that only advertised Modern Standby/s2idle, didn’t officially support S3, but iirc still advertised it on Linux. Not sure if S3 was problematic, but I just used s2idle on that XPS anyway.
