Keybinds that contain XF86* keys don't work when combined with a modifier

Description

When I create a keybind that contains only a XF86* key (like XF86MonBrightnessUp) and no modifier key, the keybind works. But if I add a modifier like WLR_MODIFIER_SHIFT to the keybind containing the XF86* key, the keybind no longer works.

Hi Kerberoge,

The Shift modifier tends to modify what you have to put in the keycode field as well. Try using the command xkbcli interactive-wayland to see exactly what is being sent when you press your desired key combination.

Ive also wondered about this, running xkbcli interactive-wayland doesnt say anything is modified. Ive also tried doing with other Modifiers, like ctrl or logo or modkey but they all dont seem to work, let me know if should provide any further detail.

Hm, I get this while pressing shift+XF86MonBrightnessDown:

seat0: keycode [ LFSH ] keysyms [ Shift_L          ] unicode [   ] layout [ Spanish (Latin American) (0) ] level [ 0 ] mods [ Mod2 ] leds [ Num Lock ] 
seat0: keycode [ FK02 ] keysyms [ F2               ] unicode [   ] layout [ Spanish (Latin American) (0) ] level [ 1 ] mods [ Shift Mod2 ] leds [ Num Lock ] 

@Hiqqup, can you paste the output you get from it?

[Kerberoge]

@sevz17 It seems that you have fn-lock disabled. Could you please try enabling fn-lock and running xkbcli interactive-wayland again?

Here's the output of xkbcli interactive-wayland:

seat0: keycode [ LFSH ] keysyms [ Shift_L          ] unicode [   ] layout [ English (US) (0) ] level [ 0 ] mods [ ] leds [ ] 
seat0: keycode [ I233 ] keysyms [ XF86MonBrightne  ] unicode [   ] layout [ English (US) (0) ] level [ 0 ] mods [ ] leds [ ] 
seat0: keycode [ I232 ] keysyms [ XF86MonBrightne  ] unicode [   ] layout [ English (US) (0) ] level [ 0 ] mods [ ] leds [ ]

sorry for the inactivity, so i get the same xkbcli interactive-wayland output as you:

[main !]~/projects/wayland/dwl xkbcli interactive-wayland
seat0: keycode [ LFSH ] keysyms [ Shift_L          ] unicode [   ] layout [ English (US) (0) ] level [ 0 ] mods [ ] leds [ ]
seat0: keycode [ I232 ] keysyms [ XF86MonBrightne  ] unicode [   ] layout [ English (US) (0) ] level [ 0 ] mods [ ] leds [ ]

but only when i comment out my configuration for those keys in my config.h:

 static const Key keys[] = {
    { 0, XKB_KEY_XF86MonBrightnessDown, spawn, { .v = darker } },
    { WLR_MODIFIER_SHIFT, XKB_KEY_XF86MonBrightnessDown, spawn, { .v = darkest } }
}

otherwise i get no output from xkbcli interactive-wayland because its intercepted by dwl. Idk maybe there is something i am not getting right about the config but the second keybinde for darkest doesnt apply.
