Rebind extra mouse buttons

I currently have a Trust Evo Advanced wireless mouse, which has some extra buttons. A "windows" button and a "zoom" button. These worked out of the box on Arch Linux, being bound to the windows and ctrl keys respectively. But I was wondering if I could somehow rebind these buttons to other key combinations, such that I can use them in Openbox's rc.xml to bind bash commands to them.

I found that the regular mouse buttons are registered in /dev/input/event5, while the two extra buttons are registered in /dev/input/event3. There the extra buttons give the following events (I'm pressing and release the windows key, and then pressing and releasing the zoom key).

Event: time 1535101633.370696, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e3
Event: time 1535101633.370696, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 1
Event: time 1535101633.370696, -------------- SYN_REPORT ------------
Event: time 1535101633.498699, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e3
Event: time 1535101633.498699, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 0
Event: time 1535101633.498699, -------------- SYN_REPORT ------------
Event: time 1535101634.322720, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e0
Event: time 1535101634.322720, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1
Event: time 1535101634.322720, -------------- SYN_REPORT ------------
Event: time 1535101634.482724, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e0
Event: time 1535101634.482724, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 0
Event: time 1535101634.482724, -------------- SYN_REPORT ------------

Is there any way to rebind these two keys, such that I can bind a bash command to them?

Re: Rebind extra mouse buttons

Does xev show their button numbers? Then, can use openbox bindings.

Re: Rebind extra mouse buttons

These are the events that xev shows when pressing the windows button on the mouse:

KeyPress event, serial 50, synthetic NO, window 0x1e00001,
    root 0x6c2, subw 0x1e00002, time 17531878, (47,35), root:(1968,861),
    state 0x10, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 50, synthetic NO, window 0x1e00001,
    root 0x6c2, subw 0x1e00002, time 17532006, (47,35), root:(1968,861),
    state 0x50, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

I don't know if you mean and actual "button number" entry, but it only shows "keycode 133 (keysym 0xffeb, Super_L)".
Super_L is the windows key (same as on the keyboard), so I think this already registers it incorrectly.
To clarify, I want the windows button on my mouse to have different functionality than the windows button on the keyboard.

I started working on a bash program to try to get something working.
It listens to /dev/input/event3, and runs a bash command whenever it receives a keypress there.
Then I will create a systemd script to keep this running, and it should work.
It isn't the best solution though, so I'm still hoping to find some way to rebind the mouse buttons.

Re: Rebind extra mouse buttons

The device likely shows up as mouse and keyboard (see "xinput")
In that case, you could write a custom xkbmap and match it by product/vendor using a dedicated "InputClass" configlet for xorg.

https://wiki.archlinux.org/index.php/X_ … c_examples

Section "InputClass"
    Identifier          "Mouseboard"
    MatchIsKeyboard	"yes"
    MatchProduct "the product as listed in xinput"
    Option	        "XkbLayout" "yourlayout"
EndSection
