Hi,
Up until recently, in order to be able to use the zoom slider on my MS Natural Ergonomic Keyboard 4000 I used a patched version of include/linux/input.h, in which a few definitions were changed so several special keys produced keycodes <= 255, like
#define KEY_ZOOMIN 0x0f6 /* AC Zoom In == 246 */ #define KEY_ZOOMOUT 0x0f7 /* AC Zoom Out == 247 */
Now X is able to process these keycodes.
Earlier this month, I upgraded the kernel and made sure that input.h still contained these changed values. However, when I use showkey I get the following output
keycode 418 press keycode 418 release keycode 419 press keycode 419 release
instead of the lower values I provided. I flipped through the latest kernel changes, but was not able to find a change that might have influenced the keycodes, only one change about the inclusion order inside linux/input.h [1]. I am currently using commit d31bf2883542cd3414674238f94123bd1d9c0b9f.
I know that the actual problem resides in the way how X handles keycodes [2] and it can (also) be circumvented using a patched xf86-input-evdev [3], but I still think this case is a bug.
Kind regards, Marcel
