You have been subscribed to a public bug: I'm on a Lenovo b570e. Since upgrade to kubuntu 13.10 the screen brightness can no longer be altered. Worked fine in kubuntu 13.04 and still works fine in windows 7 (dual boot).
I tried - using the special keys (fn-key + arrow up/down). This was my default way to change brightness in 13.04. In 13.10 it doesn't even show the brightness 'progress bar' (see attachment if you don't know what bar I mean) with the new percentage (fn-key + arrow left/right to change volume still works fine by the way and DOES show the bar) - installed and tried xbacklight -set 50. This shows the brightness 'progress bar' but the screen brightness doesn't actually change. - use the battery widget which also has a slider for the screen brightness. Again, it shows the brightness 'progress bar' but the screen brightness doesn't actually change. I read the instruction below about finding the package but I have no idea. Clearly it's not a GUI level issue since both the widget and xbacklight don't work so it's deeper but I don't know where. other people with the same problem: - http://askubuntu.com/questions/364868/brightness-at-100-since-updating-from-kubuntu-13-04-to-13-10 - http://www.kubuntuforums.net/showthread.php?63855-Problems-upgrading-from-13-04-to-13-10 ** Affects: linux (Ubuntu) Importance: Low Status: Incomplete ** Tags: bot-comment -- can not alter display brightness after upgrade to 13.10 https://bugs.launchpad.net/bugs/1245288 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
