I have no idea how to troubleshoot this. Manually suspending works, and it suspends automatically usually about 1 - 2 days after rebooting, then suddenly even the screen won’t turn off.

i use cinnamon. and every suspend option works when done manually in terminal or gui.
That seems like a policy kit issue. Maybe the system doesn’t have the permissions to do it automatically. XFce usually has such problems in other distros, but I haven’t heard one on mint with cinnamon.
Another thing to look at is what graphics card you’re using. With nvidia you can get some weird suspend issues.
Finally, install a newer kernel to see if that fixes the issue.
