Brightness events should be generating KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN - is that not happening? No, they are not generating those events (can't see in xev). On enabling CONFIG_ACPI_PROC_EVENT (by recompiling the kernel), at least acpi_listen generates correct output. But xev never shows KEY_BRIGHTNESSUP or KEY_BRIGHTNESSDOWN, in either case. You won't see them in xev if you have a power manager that's taken a grab. Can you install evtest and run it against the Sony Vaio keys device and see whether they appear there? evtest does show that key events are caught. I had a talk with the maintainer of this module (Mattia Dongili). He told that the problem may be occurring because X protocol can't handle keys with scancodes > 255 (http://bugs.freedesktop.org/show_bug.cgi?id=11227). Is there any way I can key scancode 470 and 471 to KEY_BRIGHTNESSDOWN and KEY_BRIGHTNESSUP respectively? I am attaching the output of evtest (event8 is the Sony Vaio Keys event handler). Created attachment 457467 [details]
evtest output
Ah, in that case we just need to fix up the keymap. I'll look into that, thanks! Hello.. Any updates on this? Will this be fixed for Fedora 14? Thanks. Bump I can confirm that brightness control keys work for me on the Fedora 15 alpha release. |
