[1.] One line summary of the problem: [HP Compaq nx6310] Function buttons for brightness stopped working [2.] Full description of the problem/report: In kernels prior to 3.16 the special function buttons of this HP Compaq nx6310 laptop used to work correctly. I could increase or decrease brightness, invoke the battery settings (mostly useless but it worked), switch to an external display or enter sleep mode. The key functions are invoked using Fn + the key with the designated function as listed below. Fn + F3 - Sleep - button/sleep SBTN 00000080 00000000 K Fn + F4 - Switch to external display - video/switchmode VMOD 00000080 00000000 Fn + F8 - Battery information - button/battery BAT 00000080 00000000 K Fn + F9 - Brightness down - video/brightnessdown BRTDN 00000087 00000000 Fn + F10 - Brightness up - video/brightnessup BRTUP 00000086 00000000 Using 3.16 or a later kernel up to the latest 3.19-rc2 none of these buttons work. Using acpi_listen I found that no events are fired in 3.16 and later kernels, but under 3.15 and earlier these buttons do indeed fire ACPI events and thus work correctly. The ACPI events fired are listed above. As part of the triaging process at Launchpad a mainline kernel bisection was done. As a result the offending commit identified is http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f82bdd0d77b6bf0dea08a1d957ab45d503f328b1 During the bisection I came across something that may be interesting with regard to the issue. While a freshly booted kernel with the issue has the functionality non-working, after going into standby and waking up it works as it did before. I verified that also with the 3.18 release kernel as well as the rc1 and rc2 releases of 3.19. This information may later be helpful when it comes to actually fixing the issue. The following outputs were generated on 3.19-rc1 but I verified the issue persists in 3.19-rc2, since the underlying module/code has not been modified.
