Lucas Clemente Vella, 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> Also, could you 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-rc1 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. ** This bug is no longer a duplicate of bug 765438 8086:2a42 [eMachines E527] On startup, the backlight is off on laptop ** Tags added: bios-outdated-3.10 needs-upstream-testing ** Description changed: I just updated to Ubuntu 11.04 Beta to find that the backlight of my monitor is off (or very low) and I can't turn it on. The backlight intensity control never worked on any previous version of Ubuntu (the Fn key controls responded, and changed a bar on screen, but never really changed the backlight). The Fn key On/Off worked before. In the new kernel, the backlight is off (or very low) by default and the controls does not work, so I can't turn it on. - Now I am using the old 2.6.35-28-generic kernel to report this bug.
