Bug Description
I am using Ubuntu 16.04 with KDE Neon User Edition on a Lenovo T510. The screen blinks periodically. I describe it as a blink because it seems to switch off and right back on very quickly, as if I had just blinked by eyes. At seemingly random times, the screen will go black except for a tiny sliver of orange or yellow along the left edge, then the machine loses power.
I have searched the logs and it seems that all logging just stops before the power outage without actually logging anything useful.
This problem began shortly after I migrated from Kubuntu 14.04, so I installed a 3.13.0 kernel from the Ubuntu 14.04 repository and the problem went away. I then tried a 4.1.38 kernel from http://
However, all of these kernels have the power outage issue:
Name Version Source
-------
linux-image-generic 4.4.0.78.84 16.04 repository
linux-image-
linux-image-
linux-image-
These kernels are fine:
Name Version Source
-------
linux-image-
linux-image-
So, it seems the problem originated sometime between versions 4.1.38 and 4.4.0.
Here is my lshw information:
