One other point of note, is after the Turn off screen when inactive for: duration specified in the brightness lock settings has ellapsed, instead of turning off the screen, it goes black (without turning off), and the mouse cursor is still visible.

[Kernel-packages] [Bug 1392101] Re: Brightness controls not working on intel igfx
I'm not so certian it is a kernel error now after some digging deeper. I've tried all of the following kernels: 3.11.10-03111015-generic 3.12.20-031220-generic 3.14.2-031402-generic 3.14.23-031423-generic 3.16.0-10-generic 3.16.0-14-generic 3.16.0-18-generic 3.16.0-23-generic 3.16.0-24-generic 3.17.2-031702-generic 3.18.0-031800rc4-generic I tried downloading and booting from the currently available Utopic iso, and as well as the latest daily image of Vivid. On the Utopic iso boot, running kernel 3.16.0-23-generic (according to uname -a), the brightness controls function absolutely fine. On the Vivid iso boot, the brightness controls no longer work. Booting my machine from the same kernel version as what was working on the iso, 3.16.0-23, the controls also still don't work. Additionally, I am noticing the following dmesg errors: On brightness down: [ 64.883616] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0.DWBL] (Node 88011a433500), AE_AML_UNINITIALIZED_ELEMENT (20140424/psparse-536) [ 64.883626] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._Q0E] (Node 88011a442c58), AE_AML_UNINITIALIZED_ELEMENT (20140424/psparse-536) On brightness up: [ 64.888952] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0.UPBL] (Node 88011a4334d8), AE_AML_UNINITIALIZED_ELEMENT (20140424/psparse-536) [ 64.888959] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._Q0F] (Node 88011a442c80), AE_AML_UNINITIALIZED_ELEMENT (20140424/psparse-536) Could there have been a userland change that is causing some mismatch or somesuch? ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1392101 Title: Brightness controls not working on intel igfx Status in “linux” package in Ubuntu: Confirmed Bug description: Brightness controls not working for me in Vivid Vervet as of 1-2 weeks ago.
