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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313830 Title: [Lenovo ThinkPad X230] LCD Backlight dims completely when disconnecting external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1313830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
