Dave Peck, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5 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 If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER 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 ** Tags removed: bios-outdated-r0170d6 ** Tags added: latest-bios-r0170d6 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in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/1088992 Title: [Sony VAIO SVE1712C5E] Backlight brightness controls not working in 12.10 Status in “linux” package in Ubuntu: Incomplete Bug description: I have recently updated from 12.04 LTS to 12.10 to enable better support for UEFI booting on my machine. Now that I have updated to 12.10 the brightness controls no longer work. They were working fine in Version 12.04 LTS. I have been debugging this problem with a very helpful person (Toz) on the Ubuntu Forums and it would be worth taking a look at this thread to see progress to date http://ubuntuforums.org/showthread.php?t=2092897 As suggested I have created a bug report with "ubuntu-bug linux" in terminal. I am happy to provide any additional information they may help resolve this problem. Regards, Dave.
