After that, I have met two similar bugs: 1. Every time I suspend my computer and re-activate it, I will get a black screen with a bleaking cursor. 2. Every time I close my laptop's LID and reopen it, I will get an empty black screen (without anything). These bugs really trouble me. It will be very helpful if you fix it. UPDATE at 2022/01/25: After I upgraded the "core" package using "snap refresh", the first bug has been fixed. However, the second bug related to laptop devices is still there.
