Christopher, thank you for quick response. As you suggested I start filling new report and while searching info for it (as I changed default configuration) I accidentally found working solution here: http://askubuntu.com/a/589100 . I downgraded Nvidia drivers (that installed earlier) from 352.x version to 304.128 and brightness controls start working like a charm. So I believe there's no need in new report now. If not or if I can help with something else please let me know. Anyway thank you for triggering me with that additional research. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1349002 Title: Screen brightness cannot be changed on HP EliteBook 8560w To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As the command - 'uname -a' reported the version of the upstream kernel and currently - reports the version of the mainline kernel, I assume that I ran the - upstream kernel and I am currently running the mainline kernel. - Unfortunately, I cannot report this bug with the command 'ubuntu-bug - linux', because I do not know how to boot my system with the original - kernel.] + [Unfortunately, installing the "upstream" kernel and the "mainline" kernel did not create additional entries in the boot menu so that I cannot choose the kernel when I (re)boot my system.
