Since the beginning, no matter what setting I put, the laptop doesn't always go to sleep and stay asleep. Most often than not, it wakes up to the lock screen. But this also happens after I switch user and land on the login screen, starting from the lock screen. Usually it stays asleep for less than 5 seconds.
I tried many setting combinations:
- Suspend closing the lid
- With the "night key"
- Setting "go to sleep" on the power button
- Changing the time so that the screensaver kick in before or after lock screen
- Disabling the lock screen startup app
I have a new ThinkPad 52 and I only have Mate installed on it, so it's not easy for me to test other OSes.
