mykrob, 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. ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => 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/557635 Title: [gm45] Intel GMA X4500HD - LCD Brightness Control no longer works Status in “linux” package in Ubuntu: Incomplete Bug description: Binary package hint: xorg This is on an Asus K50IJ laptop with Intel GMA X4500HD graphics. In the previous release (Karmic), the LCD brightness adjustment both on the keyboard, as well as the auto-dim for power save, worked flawlessly. As of today (April 7th, 2010) with all updates run, this still does not function for me in Lucid. The hotkey press does invoke the onscreen display that shows that an adjustment should be taking place, although it has a definite delay for subsequent presses. The actual screen brightness, however, does not change. Needless to say, this also effects battery life. In Karmic, I was able to run about 3 hours on battery, now I can get right at about 2 hours, presumably due to the extra battery consumption necessary to run the screen without being able to reduce brightness. The output of lshw is attached, hope this helps.
