The screen is fully black. I found it not a bug from any desktop session managers because all desktop environments (openbox/mate) will encounter this issue without exception. Once I accidentally close the laptop lip, I have no way to wake it up (e.g. press power button, ..) but to request for a FORCE-shutdown. ===================================================================== ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-generic 4.13.0.17.18 ProcVersionSignature: Ubuntu 4.13.0-17.20-generic 4.13.8 Uname: Linux 4.13.0-17-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version k4.13.0-17-generic.
