Mantas Kriaučiūnas, please do not change anything on this report as you are not the original report. This is not a "every HP I tested with.." report, and that is not how linux (Ubuntu) bug reporting works.
Despite this, if you have a bug in Ubuntu, the Ubuntu Kernel team, Ubuntu Bug Control team, and Ubuntu Bug Squad would like you to please file a new report by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via: ubuntu-bug linux For more on this, please see the official Ubuntu documentation: Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices Ubuntu Community: https://wiki.ubuntu.com/ReportingBugs When opening up the new report, please feel free to subscribe me to it. Please note, not filing a new report would delay your problem being addressed as quickly as possible. Thank you for your understanding. ** Summary changed: - HP ProBook 4540s and 4740s brightness control problems + [HP ProBook 4540s] brightness control problems ** Attachment removed: "/var/log/Xorg.0.log file when using 3.8.0-29-generic kernel" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1208257/+attachment/3776767/+files/Xorg.0.log ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208257 Title: [HP ProBook 4540s] brightness control problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1208257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
