Public bug reported: System: Lenovo Thinkpad T530 laptop OS: ubuntu 14.04 LTS, kernel 3.19.0-66-generic 64bit lsb_release -rd Description: Ubuntu 14.04.5 LTS Release: 14.04
With the above configuration the keyboard backlights and screen-top illuminator work as they are supposed to. In August I received the 1404_HWE_EOL update popup. Image taken today is attached. I installed the ubuntu 1404_HWE_EOL which installed (I think) some 4.4 kernel. After installing, the keyboard backlights and screen-top illuminator come on without hitting the special keys. When it returns from screen saver when I hit the return key these lights come on also. If I reboot to the old kernel all is well. So something is broken in the kernel that is installed with the 1404_HWE_EOL So I deleted this new kernel for now. The popup comes up constantly for almost 4 months now, many many times per day. This is a huge annoyance. More seriously is that no other updates are coming in. This poses security issues at a minimum. Accepting the update causes the backlights and screen-top illuminator to go on with every screen saver operation which is just as annoying.
