Title:
Laptop Wake-up bug from Current Ubuntu 18.04 Kernel
Status in linux package in Ubuntu:
Expired
Bug description:
The laptop is thinkpad, and when I use testing version of Ubuntu
18.04, close the lip, and then unable to wake up the linux session
again. 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.
I just confirmed that this bug is from kernel 4.13, and replacing it
into 4.4 from Ubuntu 16.04 will get fixed.
