    I'm having a strange problem while using the Lock Screen function.

    1. When I lock my screen and leave my computer idle, it sometimes straight-up restarts the computer.
    2. When I lock my screen and leave my computer idle, it sometimes shows that the power and num-lock LED's are on; but I'm unable to wake it up from that state - so I have to use the power button to shutdown and start it again.
    3. When I lock my screen and leave my computer idle, it sometimes just shuts down. This happens only when the flap/lid is closed.

    Barring a few times, when I check immediately after locking the screen if everything is fine; the lock-screen shows up properly - with an option to unlock with my password. But, after a while; after the second time it goes dark; the lock-screen stops working and one of the above three scenarios occur.
    Sometimes though, right after locking, the touchpad and the keyboard become non-responsive and I realise that I'm in scenario 2 mentioned above.

    I have tried everything that I could find - using tweaks to ignore the lid-switch; using the settings to turn-off auto lock-screen, screen-dimming, etc.; adding MUTTER_DEBUG_KMS_THREAD_TYPE=user to my /etc/enviroment file; but absolutely nothing works! The unreliable behaviour of the lock-screen function remains.

    I'm in dire need of help! I implore somebody to help! Please!
