It goes into a black screen and then the only option left is to force shutdown (using the power button) and turn on again. Please help as it is really annoying and I have to shut down every time I need to close the laptop or transport it.
Laptop Model: Acer Aspire E 15 (E5-573-5108)
As discussed in this answer, the problems about suspend features in Ubuntu are actually a bug. I don't know if it is related but Linux Mint disabled the suspend feature as well.
My advice is to wait till they solve before trying it, since only specific hardware devices are affected by this issue. There is a discussion in here talking about that.
