Geoff Flarity, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux REPLACE-WITH-BUG-NUMBER If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: bios-outdated-66cn55ww ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: New => Incomplete -- 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/1259369 Title: Built-in display brightness drops to 0 after monitor rearrangment Status in “linux” package in Ubuntu: Incomplete Bug description: I have a Lenovo Ideapad Yoga 13. I use it with an external monitor via HDMI at home and at work. If I re-arrange the monitors in the display settings (which is to the left/right) at home my laptop screen (build- in monitor) goes black. Turns out the backlight brightness gets set to 0. I can just increase the brightness using the hardware button, but this is still super annoying. Note, I had to follow this to get the brightness keys working in the first place: http://askubuntu.com/questions/375621/brightness-0-on-lenovo-g500s-on-startup-boot Thanks!
