poetzmij, 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 CD images are available from http://www.ubuntu.com/download/desktop .
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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in 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 and remove the tag: needs-upstream-testing This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: needs-upstream-testing 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. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER 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 Please let us know your results. Thank you for your understanding. ** Description changed: When changing the brightness on my Dell XPS 14" some incremental states of brightness are broken(leave the screen brightness completely off, and i cant see at all) on mine there are 16 states, the first 9 work then 10,11,12,13 are broken 14 works , and 15,16 are broken. (these numbers are going from max brightness going down so 1=max brightness) This is extremely inconvenient for me, I cannot set the screen to dim in power savings because of this, and even worse in 11.10 because so far i don't see an option to turn that off at all in settings. I am using the Nvidia binaries if that is important. - --- + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
