Seeing same thing here with Chromecast remote. Half of the buttons are way above 255 and won't map in KWin.

As a workaround, you could use udev to remap these keys to keys that KDE recognize: https://wiki.archlinux.org/title/Map_scancodes_to_keycodes. To support this feature, maybe we can use this: https://doc.qt.io/qt-6/qkeyevent.html#nativeVirtualKey These keys are defined in evdev and I can use them perfectly remapping them to other keys so this shouldn't be an issue. https://github.com/philipl/evdevremapkeys/commit/e5f251720c470f047549b59acff16ef701e28120 devices: - input_name: 'Chromecast Remote' output_name: remap-kbd remappings: KEY_SELECT: - KEY_ENTER 588: - KEY_PHONE KEY_SCREENLOCK: - KEY_POWER KEY_TV: - KEY_LEFTALT - KEY_F4 589: - KEY_MEDIA KEY_BACK: - KEY_BACKSPACE KEY_HOMEPAGE: - KEY_LEFTMETA (In reply to Parker Reed from comment #4) > These keys are defined in evdev and I can use them perfectly remapping them > to other keys so this shouldn't be an issue. Yes, I know that they are defined in evdev. Unfortunately KDE uses Qt::Key to handle these stuff, and since Qt::Key doesn't define these Keys, KDE is having trouble handling these. ok, fair, and I'm guessing we use the evdevkeyboard backend for Qt::Key? or would that be the lbinput backend https://invent.kde.org/qt/qt/qtbase/-/tree/dev/src/platformsupport/input |
