Thanks for the tip! I have tried to use evtest and here are results.
Key I: ------ I still get two key press events for this button and it is puzzling how I could use it to get a single action. Event: time 1331919071.656104, type 4 (EV_MSC), code 4 (MSC_SCAN), value db Event: time 1331919071.656109, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 1 Event: time 1331919071.656110, -------------- SYN_REPORT ------------ Event: time 1331919071.656913, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2d Event: time 1331919071.656917, type 1 (EV_KEY), code 45 (KEY_X), value 1 Event: time 1331919071.656918, -------------- SYN_REPORT ------------ Event: time 1331919071.658889, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2d Event: time 1331919071.658892, type 1 (EV_KEY), code 45 (KEY_X), value 0 Event: time 1331919071.658893, -------------- SYN_REPORT ------------ xEvent: time 1331919071.661927, type 4 (EV_MSC), code 4 (MSC_SCAN), value db Event: time 1331919071.661932, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 0 Event: time 1331919071.661932, -------------- SYN_REPORT ------------ If I press left meta key or 'x' on the keyboard, they produce identical events: Event: time 1331919098.264146, type 4 (EV_MSC), code 4 (MSC_SCAN), value db Event: time 1331919098.264151, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 1 Event: time 1331919098.264152, -------------- SYN_REPORT ------------ Event: time 1331919098.368375, type 4 (EV_MSC), code 4 (MSC_SCAN), value db Event: time 1331919098.368379, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 0 Event: time 1331919098.368380, -------------- SYN_REPORT ------------ Event: time 1331919136.502868, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2d Event: time 1331919136.502873, type 1 (EV_KEY), code 45 (KEY_X), value 1 Event: time 1331919136.502874, -------------- SYN_REPORT ------------ xEvent: time 1331919136.569219, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2d Event: time 1331919136.569223, type 1 (EV_KEY), code 45 (KEY_X), value 0 Event: time 1331919136.569224, -------------- SYN_REPORT ------------ I noticed that key I, left meta an 'x' has these scancodes: 0xe0 0x5b 0x2d 0xad 0xe0 0xdb Key I 0xe0 0x5b 0xe0 0xdb left meta 0x2d 0xad 'x' Is there a way to tell apart key I from the combination of the other two? Or the only way to make use of that button is to assign some function to LEFTMETA+x? Key II: ------- Event: time 1331919857.440828, type 4 (EV_MSC), code 4 (MSC_SCAN), value 85 Event: time 1331919857.440832, type 1 (EV_KEY), code 224 (KEY_BRIGHTNESSDOWN), value 1 Event: time 1331919857.440833, -------------- SYN_REPORT ------------ Event: time 1331919857.440839, type 1 (EV_KEY), code 224 (KEY_BRIGHTNESSDOWN), value 0 Event: time 1331919857.440840, -------------- SYN_REPORT ------------ Event: time 1331919857.443935, type 4 (EV_MSC), code 4 (MSC_SCAN), value 85 Event: time 1331919857.443937, -------------- SYN_REPORT ------------ If I use Fn+F4 no event is reported, but display brightness is reduced. Can I somehow assign different function for key II? Key III: -------- Event: time 1331920020.869582, type 4 (EV_MSC), code 4 (MSC_SCAN), value 84 Event: time 1331920020.869587, type 1 (EV_KEY), code 163 (KEY_NEXTSONG), value 1 Event: time 1331920020.869588, -------------- SYN_REPORT ------------ Event: time 1331920020.872227, type 4 (EV_MSC), code 4 (MSC_SCAN), value 84 Event: time 1331920020.872231, type 1 (EV_KEY), code 163 (KEY_NEXTSONG), value 0 Event: time 1331920020.872232, -------------- SYN_REPORT ------------ If I use keyboard for the same action (Fn+F10), I get the same keycode, but different MSC value: Event: time 1331920028.157210, type 4 (EV_MSC), code 4 (MSC_SCAN), value 99 Event: time 1331920028.157215, type 1 (EV_KEY), code 163 (KEY_NEXTSONG), value 1 Event: time 1331920028.157216, -------------- SYN_REPORT ------------ Event: time 1331920028.162232, type 4 (EV_MSC), code 4 (MSC_SCAN), value 99 Event: time 1331920028.162236, type 1 (EV_KEY), code 163 (KEY_NEXTSONG), value 0 Event: time 1331920028.162237, -------------- SYN_REPORT ------------ Can I somehow make X recognize that key III is different from Fn+F10 by using this difference in MSC value? Another question is - How do I assign the function I want to the key? E.g. I want for the key III to turn off display backlight (equivalent to "xset dpms force off"). In Gnome key bindings it looks that I can use only normal keyboard functions together with control keys (e.g. <Alt>) to set them to execute a predefined function. Is there a way to set it to an arbitrary key - my key III? In X11/xkb/keycodes/evdev I found this: <I253> = 253; // #define KEY_DISPLAY_OFF 245 Would it be the same as "xset dpms force off"? How could I assign key III to <I253>? Any help would be appreciated.
