[Kernel-packages] [Bug 1313830] Re: [Lenovo ThinkPad X230] LCD Backlight dims completely when disconnecting external monitor
This seems to be a regression, that had happened not long ago. Currently I am experiencing this bug with 3.13.0-44-generic (backported to Ubuntu 12.04) on a T420s. It applies to the VGA port too. However, I used external displays from time to time, and do not experience this bug about two month ago. So for me, it appears to be added by the last two moths. However, the backported kernels may be a little delayed, so others may experience this bug earlier this year. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1313830 Title: [Lenovo ThinkPad X230] LCD Backlight dims completely when disconnecting external monitor Status in linux package in Ubuntu: Fix Released Status in linux source package in Trusty: Confirmed Bug description: After undocking with external DVI monitor connected to dock the laptop's internal LCD dims all the way (backlight still on, but as dim as it goes).

[Kernel-packages] [Bug 1313830] Re: [Lenovo ThinkPad X230] LCD Backlight dims completely when disconnecting external monitor
It's too hard to reproduce this bug because I have not the same hardware. I have tested it on three types of laptop, but can't reproduce this bug. They are: 1. T540P with Displayport monitor 2. T440s with Displayport monitor 3. x230S with Displayport monitor. We have no external dock to touch DVI monitor. All the laptop are installed with ubuntu 14.04 and the kernel is 3.13.0-24-generic. I note that Yaiza Bailen has the bug on T420 and T420s with Displayport monitor, which may be similar with my #2 laptop, but it can't be reproduced. It seems that I need to get the same hardware to reproduce the bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1313830 Title: [Lenovo ThinkPad X230] LCD Backlight dims completely when disconnecting external monitor Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Confirmed Bug description: After undocking with external DVI monitor connected to dock the laptop's internal LCD dims all the way (backlight still on, but as dim as it goes).
