apport information ** Tags added: apport-collected saucy
** Description changed: After upgrading to Saucy, on my Lenovo IdeaPad Z570 with Intel HD Graphics 3000, it is no longer possible to control the LCD brightness using the hardware brightness control keys. Likewise for the KDE power management settings or the battery icon on my Kubuntu Plasma tray. (I don't use GNOME/Unity.) Until Raring I did not have this problem. There is a workaround available from http://askubuntu.com/questions/362894/changing-the-brightness-stopped- working-in-13-10-saucy-salamander i.e. doing the following command on a terminal: echo 150 | sudo tee /sys/class/backlight/intel_backlight/brightness where 150 is on the scale of 0 to whatever is given within /sys/class/backlight/intel_backlight/max_brightness. Based on this I wrote a GUI which however needs to be run using sudo/kdesudo/gksudo. I have attached it. - Bug #1241745 also relates to the same problem on Saucy but apparently - relates to an NVidia driver and I was asked to track this as a separate - bug - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241745/comments/17 + Bug #1241745 also relates to the same problem on Saucy but apparently relates to an NVidia driver and I was asked to track this as a separate bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241745/comments/17 + --- + ApportVersion: 2.12.5-0ubuntu2.1 + Architecture: amd64 + DistroRelease: Ubuntu 13.10 + InstallationDate: Installed on 2013-10-19 (38 days ago) + InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) + MarkForUpload: True + Package: xserver-xorg-video-intel 2:2.99.904-0ubuntu2 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 3.11.0-13.20-generic 3.11.6 + Tags: saucy + Uname: Linux 3.11.0-13-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1255428/+attachment/3918407/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1255428 Title: LCD brightness control keys and widget do not work on Intel Graphics on Saucy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1255428/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
