--- Comment #51 from Henrique de Moraes Holschuh <h...@hmh.eng.br> 2009-07-08 02:18:29 --- Ok, I am looking at the DSDT, and the first thing I notice is that you have two new hotkeys in there I have never heard about, so please tell me if thinkpad-acpi has been complaining about unhandled HKEY events on the kernel log. Now, back to this particular issue: As usual with Lenovo DSDTs, when anyone first calls _BCL, it switches to ACPI-controlled brightness mode, by storing 1 to the \NBCF trapdoor. Loading either thinkpad-acpi or ACPI video will do it. After that, the brightness keys will _NOT_ do anything but cause ACPI events. As you guys may have suspected, GPE _Q15 is hotkey brightness-down pressed, and _Q14 is the same for brightness-up. Their handling is pretty normal, the same as it is done in all Lenovo Intel-based thinkpads, so I'd say you have a busted X.org or userspace if it is going weird on you. Zhang-san, I suppose the ACPI brightness stuff in the DSDT was checked and it is sane? If so, then we definately can blame userspace, X.org, or kernel DRI, or something in the OpRegion firmware. Either that, or _ALL_ Lenovo thinkpads with Intel GPUs are broken, but I suppose we'd be getting a lot of reports if that was the case... As for thinkpad-acpi, well, the DSDT will give me the events I need (HKEY 0x1010 and 0x1011), so I can send KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN to userspace. Which is somewhat likely to screw up and not do what you want, but that's not something *I* can fix. I will change the driver to report those input events when in vendor brightness mode on Lenovo thinkpads. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
